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 The API has been accepted as a W3C deliverable and this repository is now maintained for historical reference, with development moved to the WebMCP explainer and org repositories.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
