WebMCP (MCP-B) is a protocol and TypeScript SDK that exposes JavaScript functions in web pages to LLMs as MCP tools, via a Chrome extension and npm transports. The API has been accepted as a W3C deliverable and this repository is now maintained for historical reference, with development moved to the WebMCP explainer and org repositories.

Use cases

let ai agents control my web app via mcp tools
expose browser javascript functions to llms
build agent-native single-page apps
register mcp tools from a website with a script tag
safe browser automation for ai agents
add model context protocol support to react or vue apps

When to choose

you want to make a website's functionality callable by AI agents through MCP
you need a browser-based MCP transport or polyfill while the standard matures
you want to experiment with the W3C WebMCP draft API today

When to avoid

you need actively maintained open-source code - the extension is no longer open source and work moved to the W3C explainer repo
you want server-side or desktop MCP integrations outside the browser
you require a permissively licensed dependency - this was AGPL v3
