1037: WebMCP is here (and you should care)

Scott and Wes talk about WebMCP with Sarah Drasner and Dominic Farolino from the Chrome team, which is the new W3C standard that lets your site hand real tools to an agent. They cover the security model, headless and multi-tab agents, and how to wire it into an app you’ve already shipped.

  And I think, Wes, you make a really good point about the multimodality of it. Not everybody's going to be using the web the same way. Like, we've known this forever. I think some people are like, oh, the web will go away. It'll just be people using it in a headless way. And then people go, no, nothing's going to change. And I think the truth is, like, these experiences are going to be done all sorts of ways. Like, even a shopping. I'm shopping as like a leisurely activity. Then I'm going to be a human in the loop in that activity because that's part of the point. But if I'm just trying to get some shirts for my son that he knows the size of and he knows what he wants, then that, you know, I'm okay with an agent doing that for me.

• 0:46Wes Bos?

  Welcome to Syntax. Today, we're talking about Web MCP. We've got two folks from Google here to talk about Web MCP. And I personally am really excited about this. It's starting to make its way into clients. And I don't think a lot of people really understand what it is or as a developer, how you should be integrating this into your site if this becomes a thing that everybody implements. So I'm stoked to talk about it. With me, we have Dominic Farolino and Sarah Drasner. They are both from Google, working on Chrome. Most people listening to this, I would say, everybody listening to this episode knows what an MCP and MCP server is, right? Everyone's slapping them into their agents. Can you just give us a rundown of like, what is Web MCP? And how is that different?

• 1:28Speaker 00

  Yeah, I mean, I think people get confused a little bit because of the name. Web MCP is on the client, not the server. And a lot of the kind of similarities are when we are thinking about the principles, like exposing tools to agents, things like that. But they're actually pretty dissimilar. The governing bodies are dissimilar. One is the Agentic AI Foundation in Linux. That's the MCP. For Web MCP, it's W3C, like other standards bodies. For Web MCP, you are really only working on it on the client. But that doesn't mean that it can't negotiate or create server actions, like kickoff arrest or GraphQL API interaction. And then also the way that people are using it agentically.

• 2:12Speaker 00

  You do have headless scenarios that you can use Web MCP. But we're also thinking about a new surface area of co-brows. And co-brows is where we're spending a lot of time, which is when you have like a human and agent on the loop collaborating on a web experience together. Dom, is there?

• 2:28Speaker 02

  Yeah, no, I think that was perfect. Like, I think the way I try to describe it to people is, you know, when you, when you give like MCP tools, traditional MCP tools to your agent, it allows you to just like enable the agent to do better capabilities inside the chat. But like, we don't have a really like an MCP for UI, like for like using the site. Like, I'm on Google Sheets. I want to do this complicated thing in the UI. I can't remember where all the 10 clicks, the functionality is hidden behind. Sorry, my cat's in the background here. And, uh, and so like, I want to be able to talk to my agent and say like, okay, I really want to, I want to like add conditional formatting to this column. And like, can you, can you do that for me? Like, if we've ever seen agents interact with websites like DOM and UI right now, it's like really, really slow. They're like screenshotting.

• 3:12Wes Bos?

  It sucks. It's awful.

• 3:13Speaker 02

  It's such a terrible experience. And it's expensive, actually, too, right? It re-enters the inference loop every time you got to click a button and do anything. But all the, the agent is thinking in terms of sort of atomic tasks. Like, I want to add a video track to this YouTube editor. I want to do something in this column at Google Sheets. And all that code actually exists in the client. And Web MCP is sort of like finally a way to let the agent get access to it and actually get, get to that code and, you know, translate its atomic tasks that it's thinking of into actual tasks that the platform or sorry, that the client app is capable of handling.

• 3:45Wes Bos?

  Yeah, it's like, like, if you look at like where we're at right now, right? Like, like you said, if you have an MCP server for something and you want to interact with it, you're typically just getting like chat back and forth. And in a lot of cases, that, that's awful. So now we have like, like MCP UI, where like you can like have these little widgets that make their way into the chat. And that's okay in some cases. But in some cases, like, you know what the best UI is? The existing app is the best UI for that, you know? So, uh, so in that case, or if there's not, then you're like, okay, well, like, hey, agent, use this browser. Or like, the site owner will strap some crappy little chat box onto the side. I don't want that either, you know?

• 4:29Wes Bos?

  And like, I've been, I've been like beating my drum, saying like, this is like clicks and clankers, meaning that like, I just want to use the UI myself, like I'm normally doing. But then I also want to just be able to do agentic stuff with that, with that application, with that website, with my own agents.

• 4:47Scott Tolinski?

  With that same functionality, yeah.

• 4:48Wes Bos?

  With the same functionality. I want to see it. I want to say, like, another example is like, if I have like six expenses in my bookkeeping software, I don't want to click them all and edit them all and select the taxes for every single one. In some cases, I do want to click things and drag them into wherever they want. But if it's like a batch job, I just want to say like, find all the expenses from my cell phone carrier and mark them as having Canadian taxes. And then it will just go off and do that for me. And then I can visually see what is happening in the UI.

• 5:18Scott Tolinski?

  Yeah.

• 5:19Speaker 00

  Well, and I think like, one thing that people don't often compare it to, which they should, is DOM actuation. Like, if you don't have something like Web MCP tools exposed, the agent is inferring what it should be doing from the DOM, from the accessibility tree, from screenshots and things. This actually gives tools to developers to be able to say, hey, this is what I want an agent to be doing with my site, instead of it just happening to them.

• 5:44Speaker 02

  It definitely lets the developer kind of express the capabilities that it knows an agent is going to want to get at from its app directly to it, so that it doesn't have to constantly do this like inference thrashing and the DOM actuation and the accessibility tree reading for every repetitive action and check if the button moved. And oh, it did. And then what happens? It can kind of let it, let it think in atomic actions and also act in them too.

• 6:05Scott Tolinski?

  And if you want to see all of the errors in your application, you'll want to check out Sentry at sentry.io/synthesis. You can sign up today and get two months for free. Sentry is just a really incredible tool for not only tracking your performance, making sure your application has no bugs, but even just seeing what goes wrong when something goes wrong. Because things go wrong all the time when we're coding. And you don't want a production application out there that, well, you have no visibility into in case something is blowing up and you might not even know it. So head on over to sentry.io/synthesis. Again, we've been using this tool for a long time and it totally rules. All right. Yeah, that's such an important thing. You, one thing I, when I've talked to some folks about Web MCP

• 6:50Scott Tolinski?

  and it arriving in Chrome, people say, is this a Chrome thing? Is this another Google thing? You had mentioned that it's involved with the standards board. So can you touch on the status of all that? And is this just a Google thing?

• 7:03Speaker 02

  No, it's definitely not a Google thing. We, we're working with, with other folks in the community, other model vendors. We're working with Microsoft on this. We're developing the API as an open web standard in the W3C. It's managed in the, what is currently the Web Machine Learning Community Group, where some other agentic kind of APIs are for the web platform. And we've been in close contact with model providers and also developers who are going to have to use the API and other browsers that we'd love to have implement the APIs. So there's been lots of discussions in the normal standards bodies gauntlet of consensus and controversy with other vendors and developers to get that pushed forward. And so I think that's, we're still early stages in all of that, all of that sort of thing. But so far, it's going really well and we've gotten a lot of good developer feedback.

• 7:48Speaker 02

  And clearly, I think the community has proven the need for something like this. Like, every time we present this to, you know, a model vendor or like an extension provider that, you know, augments Chrome with some agentic capabilities, they're always like, this is what we, what we want. Like, we want an actual, like, clear capability layer to talk to the site instead of have to like burn the user's wallet through inference loops and screenshots and all this stuff that takes way too long.

• 8:12Wes Bos?

  Yeah, and I know you guys work at Google, but like, the idea was, is that like, whatever client you're using, right? Like, if you're using, like, it's in ChatGPT Desktop right now. If you use the built-in ChatGPT Desktop browser, or I think the Chrome extension or whatever, it will surface those tools via like, we'll talk about the API in just a second of how you as a developer can implement it. But it's, it's any client, right? This, hopefully eventually will work in like the Claude Desktop or Gemini or like any client that wants to be able to do this. It should be able to just open up a browser and say, ah. Here are the tools that I have available to me.

• 8:52Speaker 00

  Yeah, if people haven't seen already, ChatGPT, ChatGPT and OpenAI came out with a big announcement that they're supporting WebMCP as a first-class citizen. There's a big hackathon. We're involved in that, even though, you know, it's across many different companies like Fersell and CloudFlare and a few others. So, yeah, it's more an ecosystem thing. Edge is definitely proponents of the spec. They're worked on the first versions of it and things like that.

• 9:20Speaker 02

  And I think the ChatGPT sort of hackathon that they've announced with WebMCP is going to be a really good way, along with the origin trial that we're running in Chrome. It's a really good way for us to pressure test the API and understand like how developers are actually using it. What granularity of tools are they writing? And then it also puts a lot of importance on the ability for the ecosystem to adapt and come up with like real evaluation metrics and determine like, I made this tool. Did it help the agentic path on my site or did it hurt it? And like, I made this change to my tool. Did that help or did that hurt? And so we're thinking in terms of like ecosystem activation to understand what it takes to write a good tool and what the API needs to do to expose tools, you know, in the most effective way to the to the agent brain so that it can it can have a really effective experience on the site.

• 10:04Speaker 02

  And so we've seen a lot of feedback from our origin trial and this hackathon coming up. That's going to help inform the API shape and all of that stuff.

• 10:12Wes Bos?

  So the API is, and the last time I implemented it was both in HTML API and a like a declarative and imperative API and like a JavaScript API. So how, if somebody has a website, they are a JavaScript developer. How do they implement this into their site so that agents can use their website?

• 10:35Speaker 00

  Yeah, I mean, I try to think about it a couple of different ways, but this is also why system design is really important. You want kind of task level milestones. I think a failure mode can here can be that people kind of attach to every little micro interaction on a DOM element. That's not exactly what's intended here. We're thinking about more like stateful or or potentially effective kind of tasks that an agent can use. We're actually collaborating with some large frameworks to investigate how we might infer tools just from your existing application authoring. So you could just write JSX, TSX. And then there's a separate potentially like reconciler pass that infers some of those tools that you can look at. But if you're working with frameworks like most of us are,

• 11:17Speaker 00

  you want to expose tools potentially via hook. I made a WebMCP tool hook that's on NPM that us in Chrome will keep up to date with the API. So don't leverage the existing DOM structure. Think in agent actions. I would also want to leverage existing APIs in your application like REST or GraphQL. If you have those, you can, those can be invoked with a tool with a really good description. We have a lot of annotation hints and those are also really important. So one really important part of the spec for me is that you, the ability to keep your site secure. So you kind of also want to go through and look at, are you exposing user-generated comments

• 12:01Speaker 00

  somewhere on your site? If so, you want to read only hint. You'd want like user-generated content hints because the agent can then say, okay, I shouldn't look at any of those and take action. That can guard against things like prompt injection attacks or, you know, agent traps or things like that. So you might want to think through, if you're a site developer, like where are you taking content that you're not sure somebody might be doing some of those harmful actions in?

• 12:30Speaker 02

  Yeah, the security side of it is is pretty, pretty vast. I mean, like, you know, historically, when we work on web platform APIs, we kind of have like two consumers. There's the browser and then there's the developer, which is, you know, writing experiences for the user. And WebMCP is unique in that like whenever we adjust the API or add new things, we have to make sure it works well for developers. Like, does it make sense for you to add this attribute on your tool? Or like, is it okay if it tools un-register at this point? But then we also kind of have to ask the inverse questions to models where, you know, it's like, can you, does your security harness like benefit from consuming this attribute? Does having a tool mark itself as read only or untrusted? Is that useful for for a security harness and an agent? And, you know, if a tool unregisters here, is that too much thrashing? Or do you guys have a caching mechanism?

• 13:15Speaker 02

  And so there's kind of like two different halves of this API and getting feedback from both sides has been has been super important. And like Wes mentioned, there's the imperative API, which is just ordinary JavaScript allows you to basically pipe in a JavaScript callback as the implementation of a tool so that the model can sort of call directly into JavaScript that the developer chooses to expose. And then there's the declarative API, which is like annotations, like like attributes on on existing forms. It's probably no surprise we find developers most interested in the imperative API so far, where most of the site code lives. But I think declarative also may have an important place because it's an easy lift

• 13:55Speaker 02

  for your like, you know, crappy local like government car registration website that is like from 1995 and has a bunch of forms on it to just like sprinkle a couple of things on and then kind of become a little more agentified and allow like those kinds of use cases. So, yeah, we're trying to collect feedback from developers on both API shapes and see what sticks.

• 14:14Scott Tolinski?

  Yeah. And so many of us think in in interfaces anyways, right? These are the interfaces that the users are interacting with. And if we view an agent as another user, you know, just being able to sprinkle that declaratively on top does feel like a big win.

• 14:29Wes Bos?

  Yeah, I see like there being just like a tan stack query plugin for this type of thing, you know? Because like I already write all my all my mutations, all my queries of like get items, update item, delete item, you know, all that all that crud that we're used to. And then I, in most cases, I probably want like 90% of those also to be available to the agent so they can just programmatically call it. So like, I see a place where you maybe aren't doing a whole lot other than just throwing in like a plugin or a hook or something like that.

• 15:02Speaker 00

  Yeah. And I mean, it also allows us to, you know, if you do exactly what Wes is talking about, you can also return structured errors back to the LLMs, you know, you plug in exactly the what success happens and the reason and so that the agent knows what failed. So you already have existing, you know, mutations, actions, dispatch kind of logic. You can leverage that existing logic for some of your tools.

• 15:26Wes Bos?

  What like what kinds of apps are like, you see like the most obvious benefit from this type of thing? I know it probably can be used for anything, but is there any like specific use cases where like, yeah, that makes a lot of sense?

• 15:38Speaker 00

  Well, we're collaborating with people like Shopify has integrated. So we're seeing a lot of use cases for Shopify. You know, obviously e-commerce is a big one. Right now, we're talking with YouTube about their in-page agent being able to surface. Like if you ask YouTube, all of the things that people might not normally get exposed to that are on the YouTube page, like playback settings. And I mean, that's one that people usually find, but there's all sorts of settings in YouTube that people don't necessarily find easily. So anything where discovery could be limited and an agent can kind of surface those discovery mechanisms. Instacart is another one where people probably want to like agendify or make their shopping experiences a little bit easier, things like that.

• 16:23Speaker 00

  We're seeing a lot of benefit from. So, yeah.

• 16:26Scott Tolinski?

  Yeah. And I'm sure you're going to uncover a lot too with this WebMCP challenge that's going on. So we have this new WebMCP challenge. The deadline is September 3rd. So by the time you're hearing this, the deadline will have passed. But it seems like there's a massive amount of submissions or at least people signing up to be potentially submitting this already. I would imagine you're going to see some really cool stuff. And Sarah, you're a judge for that, right?

• 16:50Speaker 00

  That's right. Yeah. And we're looking at like creative uses for WebMCP. We're looking at for the good of humanity. We're looking at, do you structure your tools well and make sure that everything is, you know, kind of copacetic and easily surfaced by an agent? So there's a number of factors we're taking into consideration with the judging. I am really excited so far. I think last I checked, it was like 5,000 entries had already gone through.

• 17:17Scott Tolinski?

  Yes, one of those will be mine. So hopefully my tools are set up correctly.

• 17:23Wes Bos?

  One of the the demos that you gave was like a 3D modeling software, which 3D modeling software and video editing software, I think, are two huge use cases for this because. Those are UIs where like, I'm not using a chat for that, no chance. But like we, all of us on syntax, we use DaVinci Resolve and we all have the DaVinci Resolve MCP running because in some cases, it's way easier to just type in the box what you want it to do than to figure out what the crazy clicks and whatever that you need to do. And I love, I've been calling it, you're calling it co-browsing. I'm here to tell you, it should be called clicks and clankers. I mean, you know, because we had, we had bricks and clicks when the, like the web was coming, you know,

• 18:06Wes Bos?

  you have the store, but you also have the online thing. Now we have the human and the agent clicks and clankers. Nobody seems to be, it's not catching on, so I'm reaching out to you to, for that help.

• 18:17Speaker 02

  We'll make it happen. But no, I agree with that, that general use case. Like I do a lot of like maker space stuff and like, you know, CAD modeling and like, there's, there's only so many times I'm going to like relearn how to do the same thing and like Fusion 360. And like, I'd really just want the chat to be able to like, okay, I can describe exactly what I want. I can kind of probably get there on my own, but it'll be quicker if you could just, you know, take my intent and map it to actions on the actual site. And so I think that kind of use case where these complicated configuration UIs, but I also still need to be involved because I need to like double check the end result or see the measurements or whatever. That, that's, I think the most, the most like immediately useful. But, but like we said, it's also pretty useful for headless scenarios. Like a lot of times if you're just messaging your, your, you know, Codex Bot on Telegram and telling it to do something, it's going to open up a headless Chrome in the back and talk to it through CDP.

• 19:03Speaker 02

  If every site it, it uses has web MCP tools or can talk to the service worker tools inside web MCP and do some background executions, it's going to make even all of the headless scenarios like just as easily if, if they're, if it's not talking directly to the server. So I really, I think it's a unlock for a lot of different use cases, clicks and clankers and headless.

• 19:20Wes Bos?

  That headless one, because I was talking to some people earlier on in web MCP and there wasn't like any headless thing now, but now you're saying there is. So like, you're saying that I could technically just have like a, like a box running somewhere with like, or, or my, just leave my laptop open. And if I have my websites open or they can open them, then I'll be able to access those sites that have web MCP?

• 19:46Speaker 02

  I think so, yeah. Like if, if you're, if you're messaging your, you know, your bot on some VM somewhere and, and it's really doesn't present a lot of UI to you unless it really needs your intervention or something like that. And I go tell it to, you know, register my car or update my, my license registration or something like that. And it navigates to the, the site, you know, the state of Massachusetts does not have like an MCP server, I'm sorry. And so, but maybe they, maybe we convince them to drop a couple of attributes on their forms on their site. And, and now, you know, my bot, wherever it's, you know, living, headless or not, you know, behind a Telegram VM or not. If it can, if it can actuate the site through web MCP tools exposed through CDP, it feels headless to me. And it doesn't really make a difference from the agent's perspective because it's just interacting with a site in any, in any way. So I think that's kind of the idea.

• 20:32Speaker 00

  I mean, if you never have to go to a site or whatever to register your license or like, I would love that.

• 20:39Speaker 02

  Yeah, exactly. Sarah promised me a promotion if we can get all those, all the details to register to sites to do that, so.

• 20:46Scott Tolinski?

  This is a perfect use case for something I'm working on because right now, every single time it does, pops open DevTools MCP specifically. I have a Mac Mini right here behind me that you might be able to see it flashing occasionally. That's because it's running DevTools MCP to export a video from this application. And this is like such a perfect, that if I, I would never need to see the interface for this. The, the process is just be able to do it headless. So that's really exciting to hear.

• 21:13Speaker 00

  Yeah, I mean, the DevTools for Agents stuff is really exciting. If you're working with web MCP, like sometimes people, we get, you know, a lot of people asking us like, how should I be debugging this? I think DevTools, Chrome DevTools for Agents or DevTools MCP is a really great way to like, send an agent off to do a bunch of things. It also invokes Light House for Agents. It also can perform audits for you. And so if you're not using that already, it can integrate with a lot of different models, including the frontier models. So that's a really good debugging journey. I think some people, maybe not everybody knows that there's also a Chrome extension that you can use. So I also tend to use the Chrome extension with, if you look, pop open DevTools in the

• 21:55Speaker 00

  application tab, you can see all of your tools listed. And then you can invoke the tools on the page and automatically see right in the page, feedback for how those tools are getting executed and some observability. So like, there's a number of different ways you can do it. Some are like headless, some are like directly in page and those are cool.

• 22:15Wes Bos?

  And what, what's that Chrome extension called? Is that just the Chrome DevTools MCP extension that's been rolled into that? Or is that a sep, is that the separate web MCP extension?

• 22:24Speaker 00

  Yeah, there's one that's right directly in Chrome DevTools. That's the one that I was mentioning in the application tab. And then the one that Scott is talking about is a more headless model that you can just run in the background and, you know, it kind of operates sort of like Playwright and Puppeteer, which are also good debugging tools as well.

• 22:41Wes Bos?

  Well, that's awesome. Another question I had, I don't know, maybe six months ago, when we first started talking about this was like, like what about multi-tab? And like, I assume that you have two tabs open and both of them expose web MCP tools. Your agent would be able to, to use both of those, right? Like one example I had is I built a shopping list application where you could add stores and you can add items to each of those stores and you can mark them off, yada, yada, right? And then I had another recipe website open and, and I wanted to get all of the ingredients from that and put them into my shopping, right? So that's two totally different websites, two totally, one had web MCP, one was simply just scraping, but like, I should be able to do that, right?

• 23:25Speaker 02

  I think, yeah, like the, you know, the agent will be able to use web MCP tools where they exist and, and make use of that site functionality when it can. But ultimately, yeah, it's the agent's sort of prerogative to understand what, what origins to reach out to, what tabs it makes sense to interact with to fulfill kind of the user journey. And this is actually one thing we've been, we've seen a lot of confusion about with web MCP. When, when folks are reviewing it from like a, a traditional web platform perspective, it looks kind of like a wonky API because it's, it's sort of like the first of its kind, like really facilitating agentic use of traditional web content. And so I think a lot of people mistake it for like, oh, this is the agents on the web API. And I think from our perspective, it's, it's really like, no, this is the like, let's give developers

• 24:09Speaker 02

  a chance at presenting something that's sensible for agents because agents are already on the web API. Like it's, agents are using the web, you know, regardless of whether, whether web MCP exists or, or not. And so, so we've been like really trying to understand, you know, like there's been a lot of confusion, for example, for security.

• 24:28Speaker 02

  It, you know, when people think through what it means for an agent to use a web MCP tool, kind of like, oh, like an agent can use this tool, but what if it has like some, some stuff from another origin like in its brain and it wants to like share that information with this tool? Isn't, and that's kind of like violating the same origin policy, right? Like that's, that's kind of scary. And that's violating cores. Like what is that, what does that mean? And I think it's a little hard to think about because we don't mind users violating the same origin policy. I'm, I'm the user, I can see all my cookies, I can see all my tabs, I can see all my origin data. But that's because the product is, is kind of serving me. And so in one sense, the agent is kind of an extension of the user and sort of punches through the traditional like web sandbox security model. At the same time, like users are not comfortable just like, probably giving the agent its entire

• 25:12Speaker 02

  identity and letting it assume it's, it's full persona like on the, on the web and just browse and do whatever it wants. And so there's only so much of this we can control from the platform perspective, which has like the same origin policy and cores and all that. And we're starting to think about what it might make, what, what it means to produce like an agentic platform like in, in the product. And instead of thinking about like the same origin policy, what is, what does a safe origin policy look like? Some, some agentic model in the browser so that the agent can know like, yeah, I should, I should be able to assume the user's identity on, on these four sites related to this task, but I shouldn't be able to do everything. I can't read all their cookies. I can't go to their bank and start making transactions. And so we're starting to think through what, what a, what a capable agentic web harness

• 25:54Speaker 02

  looks like in a browser that integrates somewhat with the web platform, but somewhat with the product to actually make agents on the web secure and also facilitate the use of web MCP through traditional web platform content. So it's a, it's a complicated model, but.

• 26:09Speaker 00

  Yeah, and like to zoom out for a second. So there's, you know, as Dom said, there's only so much you can do on the platform side and for site developers, but we're also talking to agent developers and our own agents about what's potential there. And I think one thing to get people to really understand is that we, this won't be solved by one thing. It has to be a multi-layered defense, defense strategy because agents can be somewhat non-deterministic and also you need both the site side and the agent side. So some things that we're thinking, we're doing within Google that we're thinking about open sourcing and making more of a standard are things like prompt injection classifiers so they can identify attacker instructions in content before instructions kind of go out.

• 26:52Speaker 00

  Critique LLMs, a lot of people know about like a secondary judging LLM. You can imagine that being applied to like web surface areas. And then also just like restricting origins, like you may want to have like that LLM that's a judge say, okay, you were supposed to go book travel for me and you can go to Expedia and United, but why are you going to my bank? Why are you going to my health site? Like to make sure that we're not going off to origins that they shouldn't. And finally, there's like this kind of special agent containment layer that we're thinking about exposing to the community so that agents can have like more of an identity that's separate from the user. Like so far, the agent is you, but you could imagine that you also, you might want to have

• 27:35Speaker 00

  an agent identity that's separate from you that like can only spend $20 a week, only has access to some information about you, only has some passwords, things like that.

• 27:45Scott Tolinski?

  Here's $20, yeah.

• 27:47Wes Bos?

  I gave my Shopify 20 bucks. There, Shopify has like, if you go to any Shopify website, they have like a forward slash agents.md with all the information about how, how to, to communicate with it. And I, you have to like explicitly give it a little bit of money and let it rep. I thought that was funny.

• 28:05Speaker 02

  Nice.

• 28:05Scott Tolinski?

  That's great.

• 28:09Wes Bos?

  Can we talk about? Something that makes me sad about the web is the performance where we went in like the process of like a year and a half, we went from it really matters how quickly your key ups happen and you should not block the thread and that we have all of these web vitals about making everything super fast. We cared so much about all of that stuff. And then these agents came around and it takes like $4 and three minutes to click a link to do something. And I was like, like this, the experience sucks. If you're, if you're, if you're out somewhere and you don't really care, but when you're waiting on it to do work, that experience is absolutely awful. Is there, is that, obviously web MCP will get that better, but will we bring vitals to agents?

• 28:54Speaker 00

  Yeah, I am actually kicking off a like, what would core web vitals look like for an agentic web thing? So there's things like, you know, if you're using, you know, Claude or Gemini or ChatGPT, that time to first token is a new metric that everybody's kind of looking at. And that kind of, those kind of streaming deltas, because you don't have just like the second it goes, but you also have the second that it like streams all of the possible input. But in co-browse, or wait, what was it? Clicks and clankers?

• 29:26Wes Bos?

  Clicks and clankers.

• 29:27Speaker 00

  Clicks and clankers. Okay, I got it. In clicks and clankers approaches, you, the thing that's fascinating about it is that some of the old Nielsen things still are like, are still some things that we're seeing here. So like, one second per tool call, five seconds before you want to see an entire action go through. If you're not familiar with that, those are some of the earliest human computer interaction things, like people don't wait longer than five seconds for a webpage. That actually has worked in like clicks and clankers approaches as well. But the thing that we didn't have in there is that when you're watching co-browse, you're not just judging the agent and the

• 30:08Speaker 00

  time, you're seeing how fast it is compared to you. Because you don't want to be doing an experience on the web where you're like, watching it and you're like, I could be clicking that faster. I could be doing this whole flow faster. And so that's the first time we're seeing metrics that might be comparative to a human.

• 30:27Speaker 02

  And the real trick is exposing that to developers. Like in the past, like we could let developers do things on their site. And we have like performance observer and that kind of, that kind of thing that lets, lets the developer get access to how long that navigation took and how long that animation transition took. And they can understand when they make changes on their site, if it affects the user experience through real user metrics. But the agentic side of things is a little trickier because like, a lot of times, the, the success metrics are kind of locked up in the agent's brain. It knows like how many model turns it took to fulfill a user, a user journey and how many user journeys, you know, it, you know, were completed with a web MCP tool and how many tools were involved and how many tools confused the agent. And so we're also trying to think through, we're super early in this, but we're trying to think through some ways to expose

• 31:09Speaker 02

  some of those metrics to developers as well. Whether it looks like some agent performance observer or some reporter API or something like that, where we can let developers actually measure the effects of the agentic targeted things that they're doing on their site. So they can know if they're actually having a positive or negative impact. Cause right now, like it's, it's slow for a lot of reasons. And web MCP tool calls make that a lot faster, but some of them are still slow. But one of the like really big challenges here is like, the whole thing's opaque. Like we kind of really have a hard time measuring like how, how changes I make to a tool impact the success rate and how they impact the latency and what's confusing the model or not. And we need the developer to transparently understand that kind of stuff on their site, or else they're flying blind and it's going to be impossible to make changes and, and measure against them.

• 31:53Wes Bos?

  Do you also have a way to like, measure just for like, regular people using it as well of like, like success rates and whatnot? Like I think back, I was booking a hotel on Expedia a couple of weeks ago. And like, I wanted to buy, I wanted to book like a suite that had a separate room and that wasn't like a filter on Expedia. And I was trying to do it entirely agentically. And I was like, this is awful. I need a map. I need photos of it. I need like all of, I need the UI. It's not a very good experience, right? And like, all these tech bros are just like, oh yeah, booked a flight for me and I bought red shoes online. And like that, that's not how regular people do, do their work, right? So like, is there some sort of like measurement that you're doing with like regular people

• 32:35Wes Bos?

  as to like, whether this is something they use and is sticky enough?

• 32:39Speaker 00

  I do think that for some of the like crux things that we're working on for agents, we are invoking like, we have a bunch of UX researchers who are looking into this so that we do these types of studies, both with like real users and then also by doing analysis of the web. And like, we have a lot of data because of Chromium being used by so many people that we can kind of leverage here. I would say that we're pretty early in like full stop, this is the way that everything works. We do have some targets. And like Dom said, I don't think that anybody's at those targets yet because these experiences are so new. People aren't even used to building out a product experience that might incorporate

• 33:20Speaker 00

  something like this flow. Like that, even just like for PMs of a site to like, think through, okay, what does that look like if somebody is going through a co-browse flow? Sometimes we've had these like deeper partnerships, but we do need like site developers and product managers and everything to incorporate that kind of thinking as these, you know, new agentic surfaces evolve. And I think Wes, you make a really good point about the multimodality of it. Not everybody's going to be using the web the same way. Like we, we've known this forever. I think some people are like, oh, the web will go away. It'll just be people using it in a headless way. And then people go, no, nothing's going to change. And I think the truth is like, these experiences are going to be done all sorts of ways. Like

• 34:03Speaker 00

  even a shopping experience, if I'm shopping to like, you know, as like a leisurely activity, then I'm going to be a human in the loop in that activity because that's part of the point. But if I'm just trying to get some shirts for my son that he knows the size of and he knows what he wants, then that, you know, I'm okay with an agent doing that for me.

• 34:24Scott Tolinski?

  And I think a lot of these things are going to evolve as we, you know, XR, whatever experiences involved with it. Like, oh, computer, show me what I look like in this shirt. Okay, now this shirt, you know? I mean, like, who knows with all that stuff? It's going to evolve as we go. Yeah, totally.

• 34:37Speaker 02

  That's definitely one of the challenges of API design and this kind of initial era. Like all of this agentic web space is super nascent. And so it's, it's, it's hard to tease out some of the patterns, you know, we're seeing and, and, you know, derive what experiences we can from, from actual MCP and see what makes sense over in web MCP. And, uh, you know, everything's, everything's new and moving so fast with, with, from the developer side and from the model side. Um, so it's kind of hard to pin this down and understand exactly what, what makes sense. Um, which is why the origin trial and the hackathon and that kind of stuff is, is a really good way for us to collect experience.

• 35:10Wes Bos?

  Have you heard from any site owners who are like resistant to this type of thing? Because like, that's like another weird spot is like, if I'm an airline, I don't necessarily know, and this is more like the MCP server way. If I'm an airline, if you ever tried to book a flight, they try to hard up sell you on absolutely everything. They, oh, what if you get sick? You $20 for, for the insurance and all of like these like, like black tactics.

• 35:41Scott Tolinski?

  GPT about to be defensive about that, right? Oh, we thought you might need this, so therefore we added this. Yeah.

• 35:46Wes Bos?

  So like, I'm, I'm wondering like, the airlines doesn't just want to be like a, like a straight up utility for just vending out the cheapest flight for this type of thing. Cause they want to be able to make, make more money as well. So have you heard any like pushback from people who own sites? And they're like, nah, we don't want this.

• 36:02Speaker 00

  Yeah, there are a couple of cases that I probably can't disclose on a podcast.

• 36:09Speaker 00

  I do think that there's, um, you know, when I look at the interest, it's far more people wanting to expose web MCP and tools because they want the agents to be able to discover and not fail. And like, I think what they're really worried about is like, oh, okay, if it's just dumb actuation and things like that, then we can't guarantee that they're going to have a good experience. They might go to some other place or something like that. So mainly it's interest. But there have been a couple of outliers of people wanting to be like, maybe we just say, everybody go away. And like abuse in that kind of direction. Um, I think in cases like that, we're still, like Dom said, we're so early

• 36:49Speaker 00

  on in trying to figure out what those loops and experiences might be. Do you empower the user? Do you listen to the site owner? Like if the user really wants to be using an agent, are you going to flat out tell them no? Like, I don't think that the industry has a collective answer for that yet. Um, but typically we try to like, put the user first. Um, and so that, you know, is a little bit of attention. Thankfully it's not that common.

• 37:19Wes Bos?

  That's good. And of those ones that are common, I, I wonder how many of them are just trying to protect their business of like, like, like, either like come along for the ride on the agent world or, or like be left behind. A lot of people are saying. So I don't think that's all of them. I think there's certainly a lot of people who can like, like I guarantee Amazon could say, nope, none of this. And, and that would be a big problem. Same with like Apple Pay at Walmart. Walmart just says, nope, you know? And like, that's a big deal. They, they're big enough to do that. But for a lot of people, they're, they're not big enough to actually to push people around like that.

• 37:55Speaker 02

  I did not know that Walmart does not take Apple Pay. That's, that's news to me.

• 37:59Wes Bos?

  They have in Canada for years, but Canada is, is a great country. But apparently US is just getting it now.

• 38:05Scott Tolinski?

  Yeah, just getting it. Yeah. End of 2026. Well.

• 38:11Speaker 02

  It's a hard space, though, right? Like, should my agent be like watching ads for me if that's like what the site wants? Like, you know, probably, probably not. Or like, should it be clicking on ads that it thinks I'm useful? Like, there's a whole monetization model that's like totally nascent here about like, what, what does agents on the web even look, look like for the traditional funding and attribution and refer and all that, all that kind of stuff model? Like, that is, that's like a whole new space. It's, it's beyond Web MCP. I mean, it's Web MCP plays a role in it. But I think, you know, we see, we see a lot of different corners of the industry rallying to answer similar questions. Like, this is kind of, you know, also related to the UCP, the Commerce Protocol spec. You know, like, there's, there's a lot of upselling there. Like, how does that integrate?

• 38:51Speaker 02

  You know, there's got to be answers with that. Um, I don't know, maybe, maybe someday there'll be like an ad viewing spec where you can view your ad through MCP. No, just kidding. But like, you know, it's, there's a lot of, a lot of new things here. And then, and then obviously, the, the natural thing is for like, large, kind of like, business conservative enterprises to, to maybe resist it and keep their traditional model. But I think ultimately, most, most vendors of that sort will end up figuring out a way to integrate industry solutions to, to, you know, enable new ways of monetization and new ways for agents to interact with their sites. But exactly how is, is unclear yet. But, uh, yeah, it's, it's going to be an interesting future, for sure.

• 39:32Speaker 00

  We are working on some things internally, but I don't think that they're totally ready for prime time. Maybe we, you know, send you all links in the future or something.

• 39:41Wes Bos?

  Send it a star way. I didn't realize this. So like, for people listening, that's ucp.dev, Universal Commerce Protocol. Um, and then I've also been keeping my eyes on the X402 project, which is the like agentic payments. I know CloudFlare is rolling out wallets soon. I know Stripe is, has their wallets in the US, which the, your agent can spend money on. So it's, that's obviously not part of Web MCP, but it is kind of related as to how do agents use the web without bankrupting everybody?

• 40:12Speaker 00

  I mean, we do examine this as part of health of the web, because in order for people to keep the web healthy, they need a way to make money off of it. So if you have like, beyond commerce, if you have a content site that makes money off of ads in order to show and display content, then you're kind of going more towards a subscrib-, uh, subs-, why can't I say subscription? A subscription model for those things.

• 40:39Scott Tolinski?

  Yeah, totally. Yeah. I mean, I mean, because the AI agents are just slurping all that stuff up now, and there goes your, your income. So yeah, yeah, it's a different world, I think, for a lot of sites that are trying to work on that model right now.

• 40:53Speaker 02

  Yeah. And I think it's definitely, I think it's important that the web evolves to try and meet, meet the moment. Like, I think there is a lot of, um, you know, understandable and natural pushback in general about the web evolving too fast, or adding too many AIs that are tailored to agentic experiences. And, you know, these things have a necessary long tail of controversy. We have like the Web MCP and the Prompt API and so forth. But like, I, I think it's ultimately a good thing that, that we're focused on trying to figure out what the web's real place is in this kind of agentic world. Because like, I'd certainly rather us all argue about a healthy web that is still relevant than a dead one that died because we, we didn't keep up with any of the technologies that are, that are coming down the pipeline.

• 41:34Speaker 02

  I think that's like a really important thing to worry about if the web doesn't really meet, meet the AI moment and, and figure out what it means to present kind of, kind of two platforms now, right? Like, traditionally, it's, it's always presented, the web platform to developers and to the user. This is things like readable streams and module scripts and anchor positioning. But like, now we probably need some like agent platform side of sort of things where, you know, I, I kind of envision a future where you can plug any agent brain into your browser. And then that agent brain can sort of get like whatever containerized access of, you know, to your, to your, your site data or things that are useful to you as the user and be constrained by the, the guardrails that the, the browser's agent harness kind of is able to provide.

• 42:16Speaker 02

  And then whether that is partition credentials or read-only views of, of certain, you know, parts of the user's persona so that they can actuate on their behalf and so on. Like, all of these kinds of things, like, are going to have to, you know, we're, we're currently working on them and we're currently trying to figure out what they're going to look like in the future and understand what it, what it means for the agent to kind of have a, or for the browser to play a role in sort of like this agent platform, like space. Because that's kind of, that's very new. Like, we've only had platform and product. And now like product is, is kind of containing like a bunch of agent primitives. And we're actually thinking about this from the extensions point of view on, on Chrome as well. Like, um, it's, it's really widely known that like a lot of agents that are living in extensions on, on Chrome,

• 42:59Speaker 02

  like, they, they need like full access to the page. And so they, they get like accessibility tree and screenshots and all this kind of stuff. But to do that, they kind of end up tripping over the debugger API and then it kind of flashes this like scary banner and enterprise clients don't, don't like it. Because the, the agent has so much direct control over the page through an API that was never really designed for agent usage. And so we're kind of stepping back and being like, what does it mean to like refactor and redesign all of these things to provide like an actual agent platform for agents to plug and play straight into your browser, but, but meet the safety standard that the browser is known for through whatever safe origin policy or harness or tool, toolset or read-only view of the user's state or data that, that makes sense.

• 43:42Speaker 02

  And I think that, that's like one really big thing I think is important for browser vendors to, to focus on. It's actually, it's the reason why we see a lot of these new agentic browsers sort of come and go from, from other companies. Like, they're, you know, spinning up their own, their own binaries and trying to encourage users to, to use them as their, as their browser. Not because they're, they differentiate themselves on the, on the web platforms perspective, but it's because they bring with them a bunch of agent tools that traditional browsers might not have thought about, you know, from, from day one. And so I think it's, it's important for all browsers to understand like what it means to kind of be an agent platform and a harness. And I imagine like a, a large suite of plug and play configurable tools and, and security policies in any kind of browser that manages an agent.

• 44:27Speaker 00

  I mean, it's a Dom's point. If you don't think about it, then you can't secure it, then you can't make it private. Like, whether or not you want agents to be on the web, or any individual browser wants agents to be on the web, they are on the web. What security has been talking about is this fourth actor, right? Like, you have the platform, the user and the site. And then all of a sudden, you have the fourth actor, which is AI agents. And they call it, you know, in security, we call it a trust diamond. Um, and that, you can't think through those pathways and actually make them safe and secure unless you're actually paying attention.

• 45:05Speaker 00

  Like, the, "You're not here, me. I can't see you" is not necessarily the approach that's going to allow us to make things safe for users.

• 45:14Wes Bos?

  So Web MCP, supported by OpenAI, Chrome, Shopify, Vercel, CloudFlare. Have you heard any peeps up or down from the, the two boogie monsters, Anthropic and Safari or, or Apple?

• 45:27Speaker 02

  Firefox and, and Safari or, or Anthropic?

• 45:32Wes Bos?

  Well, Anthropic, because this would have to be in Claude in order for it to be, like, everybody to use it, right? They're such a big player, at least right now. Um, and then like Apple and, and Mozilla as well, I guess. Yes.

• 45:45Speaker 02

  Yeah, we, we have heard from all of them. Um, like, we've been talking a lot with, with Mozilla about the imperative API. They're, they're pretty interested in it. Um, and they've expressed some, some public support to the imperative side of things from Web MCP, which is awesome. We've been in discussion with, um, yeah, other, other model providers like Anthropic and browsers like Safari. I think probably we can comment on some of the stuff that's already public. I think there's a lot of enterprise interest from, from both parties, uh, because this is where like a lot of knowledge work happens. Um, and so making sure that there's widespread adoption among developers that, that can help enable Web MCP in these, in these products makes a lot of sense. And, yeah, Sarah, do you have anything to add to that?

• 46:27Speaker 00

  Yeah. So we are talking to all of the people mentioned. Um, they are investigating what it means for them. Um, and so as part of that investigation, are doing due diligence on what they want to be supporting, what they don't want to be supporting and formulating thoughts. And so I would say we're still in the kind of like, uh, meeting with people and talking through things, stage of things. Um, and not in the like, here's what we can formally announce stage of things, uh, but it is covered territory.

• 46:54Wes Bos?

  That's cool. I had used a, um, like, a Web MCPB, um, extension, which basically turned my Web MCP websites into like a, like a proper MCP server. And that was really cool, because then I could just, I could take that MCP server and put it into anything that supported MCP. And, and then I could, I could just chat with it, right? Now, that was cool, because I, I did, I slapped it into Claude. I typed into Claude, but I could see it controlling my browser. So I thought, like, maybe that will be an experience at, at one point as well, even if they don't end up supporting it.

• 47:30Speaker 00

  Yeah, I just talked to him last week. He's really a like, I don't know if you've talked to the creator of WebMCP. I think he does a really good job of like thinking through what people might need because he used to be a consultant for all of these kind of like Salesforce and other companies. So he's kind of good at those like glue layers. We are incorporating a polyfill that, you know, he worked on previously and things like that. So he's a really good community member and I like the work that he's been doing.

• 47:59Wes Bos?

  This is Alex Nehas. Yep.

• 48:02Speaker 02

  Yeah, he's been great. He's been an awesome partner. He was one of the original folks that came up with kind of the original shape and idea of what WebMCP might look like. And he's pretty active in the community group. It's been great working with him and, you know, building polyfills alongside of him and so on. So, yeah. But you can definitely imagine that any model vendor that, you know, has a Chrome extension or really wants to be able to perform knowledge work tasks in user wants, you know, for users really, really wants something like this. Like, it's amazing. I mean, every time we bring it up to people and they're just like, their eyes light up and they see that all the benchmarks go green and they're kind of like, oh, my gosh, yes.

• 48:39Speaker 02

  This is saving time, dollars, latency, everything. And there's already been a bunch of public like benchmarks about this that actually integrate, they kind of build their own harness, sort of like MCPB, that sits in between WebMCP tools and the Claude code harness or the OpenAI extension and so on. So you can actually get a feel for like what it would, what it would look like for these extensions and model providers that don't support WebMCP today. Like what it would look like for them to actually do so from a performance and a usability perspective. And so far, it's been, it's been really good feedback.

• 49:10Scott Tolinski?

  Yeah. Is there anything else that we haven't hit that you all want to make sure we cover?

• 49:16Speaker 02

  I think, I think the one thing I'd love to encourage is the community to keep tabs on the W3C spec. You know, every, every day we get new issues filed, bugs or proposals or additions and so on, straight to the repository. It's a really good way of getting real world developer feedback and real world model vendor feedback. Like we have extensions, you know, folks that build kind of like community DOM actuating extensions. They love to chime in on the repository and help us understand what parts of the API make sense for their harness and what doesn't. And so we would love people to just stay, stay in touch and keep in the loop with the API and also provide their feedback to us because it's all super useful.

• 49:55Speaker 02

  Like we mentioned a few times, this stuff, it's a really, really early space and we're figuring it all out and we're trying to make sure what, what ways we can impact the security and the usability of the API. And so I would encourage people to stay in the loop and start experimenting. There's been some really, really great tools being built. There's ORA.ai, which is a tool that has been built by one of the MCP apps, MCPUI co-creators. And this, this kind of like helps you measure how agentic journeys are like actually happening on your site and how WebMCP tool calls are being used by real world agents. And it's a good like benchmarking kind of framework that we've been, you know, looking at and thinking through for, as a way to understand how useful tools like really are.

• 50:39Speaker 02

  And so the more, the more feedback like that we get from the community, tools being built to measure how good, how good WebMCP tools and agentic experiences are. All of that like really helps the industry create something measurable and effective from the use of not just WebMCP, but anything agentic on their sites. So we would encourage developers to get as involved in that sort of space as possible because I think it's super useful feedback for the browser engineers and model vendors as well.

• 51:07Wes Bos?

  That's great. Yeah, like seriously, folks, listening to this, try build something, slap it in your site, try build like a little to do app or whatever and like, and like give your feedback now. Cause like, one of my first pieces of feedback was like, I want this to be headless as well. And like, I don't, I don't think that was me, but like now it is, right? And like provide your feedback now so that we can like nail this. Cause even if you look at like the, the journey of MCP, it's had so many high highs and so many low lows. People have been said it's over like six times since it's been released and it's just, because we didn't know what it needed to look like. So like chime in and then that's super helpful.

  That was so funny. I was, I was at the MCP Dev Summit Conference in New York City in March and, you know, the whole, this was like when skills were happening and CLI was kind of popping off and everything was MCP is dead. And so they actually threw an after party on one of the nights at, at some like, kind of like dark, nice cocktail bar in Manhattan. It was called MCP is Dead, the Funeral. And they had like a quartet and they were like singing sad songs. It was like, they went so far. And so I'm like, oh my gosh, but yeah, yeah. It's entertaining to see, see all the community hype and unhype about random things as, as they fluctuate. But yeah, otherwise, thanks for giving us the opportunity to chat about WebMCP and kind of, you know, talk through what, what we think the future of all of this stuff might, might look like.

• 52:30Speaker 02

  You know, we're marching forward as fast as we can, but also a lot of this stuff is, is pretty early and speculative. And so, you know, we'd love to stay in touch and keep, keep an idea on what developers are building with, with these tools and how they work in public.

• 52:44Scott Tolinski?

  Amazing. So now is the part of the show where we give you the opportunity to share something that you're really interested. We call them sick picks. These are things that are just in general that you're enjoying in life right now. Could be literally anything from a TV show, a podcast or a, what did we sick pick? I'd pick, I'd pick some sanding paper. So you can pick whatever you want. So Dominic, Sarah, do you have sick picks for us today?

• 53:07Speaker 02

  What grit?

• 53:08Wes Bos?

  Yeah. Oh, he's got, he's got all the grits. He's got a wet sander.

• 53:13Scott Tolinski?

  Oh, it's, yes. Oh, I got like nine different grits. It was for sanding 3D prints. I had a little 3D printed device that I sanded down and it's so smooth. You can't even tell it's 3D printed. It's beautiful.

• 53:23Speaker 00

  I thought yours would be more about like dancing and breakdancing.

• 53:27Scott Tolinski?

  No, we have tons of these. I

• 53:30Wes Bos?

  Sick picking for eight years now.

• 53:32Scott Tolinski?

  Many, many dance competitions. Absolutely. Yes.

• 53:36Speaker 02

  I'm happy to go. Yeah. Like one thing I was, I love really, really good writing. And so one thing I would love to recommend to people is this, this book I've been reading called The Sense of Style by Steven Pinker. It's a book about writing and it's a kind of a, a style guide to the classical sense of writing, which is like its own, its own style on its own. And it's written, written really, really well. I like to write and I try and, you know, be as good of a writer as I can. And I love reading really persuasive, succinct, concise, impressive prose. And I think this book is filled with that. So I'd recommend it to people for sure.

• 54:11Wes Bos?

  Whoa. I'm going to feed this into my prompt, into my, into my client here.

• 54:21Speaker 00

  I think mine is, if you all like Minecraft or if your kids like Minecraft, there's a game called Vintage Story. It's a harder version of Minecraft and it's sandbox, but it's very survival style. So you're the first human, you have to survive the winter. It has some like Lovecraftian horror vibes and elements and you can mod it to your liking, but it's really hard and really fun. So if you're like, you know, into Minecraft and you want like to level up and some difficulty, me and my kids are just having so much fun playing that.

• 54:54Scott Tolinski?

  Is it, can you play multiplayer or are you just taking turns? Oh, okay.

• 54:57Speaker 00

  Yeah. Yeah. It's actually really fun multiplayer because then everybody can like help with different tasks and things like that. You can do like a kind of collaborative effort.

• 55:05Scott Tolinski?

  My kids are both into Minecraft right now. So perfect, perfect opportunity. Yes.

• 55:10Speaker 00

  Nice.

• 55:10Wes Bos?

  24 bucks too. I love, I love that. You don't have to pay monthly for this thing. You just buy it once. That's great.

• 55:17Speaker 02

  I'm so sick of all the subscription things.

• 55:19Wes Bos?

  Yeah, me too. I'm over it.

• 55:21Speaker 02

  It's too much.

• 55:23Wes Bos?

  All right. Next thing we have is shameless plug. This is, it gives you a chance to plug as many and whatever things you would like. You guys bring your plugs today.

• 55:32Speaker 02

  Yeah, I would say for me, mine's pretty boring. Just feel free to follow me on Twitter or X, just at Dom Farolino. Should be pretty easy to find. I tweet about random web platform API things that I'm working on and stuff and specs and WebMCP. And so I'd love to hear from people over there.

• 55:48Speaker 00

  I'm Sarah Edo on X and other platforms. One shameless plug I do is that we're both speaking at Agent Con in San Jose. That's run by the Agentic AI Foundation of Linux Foundation in October. So they gave us a discount. So you can get 25% discount with Community 25.

• 56:06Scott Tolinski?

  Wow. Awesome. Thank you for sharing that. We'll make sure that's all linked up too.

• 56:10Wes Bos?

  Cool. All right. Well, thank you both for coming on. Appreciate this. Let us know down below in the comments what you think of WebMCP and we'll catch you later.

• 56:18Speaker 02

  Peace. Thank you.
