WebMCP Directory: Websites AI Agents Can Use
WebMCP lets a website publish its actions as tools, so an AI agent calls a function instead of guessing which button to press. This directory lists sites that already do it, each with a plain description of what an agent can do there and which tools it offers.

What is WebMCP?
WebMCP is a proposal from the W3C Web Machine Learning Community Group, first published in August 2025 by engineers from Microsoft and Google. A page tells the browser "these are my tools", with a name, a description and the data each one needs. An agent visiting the page can then call those tools directly, instead of clicking through the interface or scraping the HTML.
WebMCP in Chrome: status today
- Chrome lists WebMCP as proposed, not shipped.
- Developers can try it from Chrome 146 by turning on an experimental flag.
- An origin trial runs from Chrome 149 to 156, extended to 162, so sites
can test it with real users.
- The specification is a living draft. It uses
document.modelContext; older
tutorials use navigator.modelContext, the previous name.
How a site exposes a tool
For developers, each tool is one JavaScript call:
document.modelContext.registerTool({
name: "search_products",
description: "Search the catalog by text and maximum price",
inputSchema: {
type: "object",
properties: {
query: { type: "string" },
maxPrice: { type: "number" }
},
required: ["query"]
},
async execute({ query, maxPrice }) {
return searchCatalog(query, maxPrice)
}
})The tool runs inside the page with the code the site already has, so it answers instantly and with the same data the user sees.
WebMCP vs MCP
MCP connects your assistant to services through a server; WebMCP lives inside a page you have open. They complement each other. The full side-by-side is in MCP vs WebMCP: differences, and servers you can use in Claude or ChatGPT today are in the MCP servers directory. Agents that use both are covered in our guide to AI agents.
How sites are listed
We find sites that expose WebMCP tools, read the tools they declare and write each listing with AI from that public information. We do not develop or audit these sites, so check the site itself before you rely on it. Running WebMCP on your site? Email envia@mcpteca.com and we will list it for free.
Frequently asked questions
What is WebMCP?
A proposed browser API that lets a web page expose its functions to AI agents as tools, each with a name, a description and an input schema.
Is WebMCP a W3C standard?
No. It is a draft in the W3C Web Machine Learning Community Group and it still changes often.
Which browsers support WebMCP?
As of November 2026, Chrome supports it as a developer trial from version 146 and as an origin trial from version 149 to 162. It is not enabled for everyone yet.
Does WebMCP replace MCP?
No. It is designed to complement MCP: MCP connects assistants to services, WebMCP lets a page offer tools to an agent that is visiting it.
Which websites use WebMCP?
The sites in this directory. Each listing shows what an agent can do there and the tools the site exposes.
Is WebMCP safe?
Tools run inside the page, with the session you already have on that site, and the browser mediates access. Sites must still validate inputs and permissions.
Is there a declarative HTML version of WebMCP?
Some sites mention registering tools with HTML attributes, but that is not part of the current specification.
How do I get my site listed?
Email envia@mcpteca.com with your site address. Listing is free.
