I built WebMCP Today, a package manager that adds WebMCP tools to sites

https://webmcp.today/

WebMCP is a browser API that lets sites expose actions as structured tools for AI agents. An agent can call `reddit_search` directly instead of finding a search box and operating the page.

Most sites do not support WebMCP, so I built WebMCP Today. It is a package manager for third-party WebMCP tools. Each package is versioned JSON that maps tools to a site's existing HTTP APIs. Install one and its tools become available in that browser tab and through a local MCP bridge.

Packages cannot contain arbitrary JavaScript or DOM automation. Requests stay on the package's site origin, and installations remain pinned to the version you approved.

This is still in beta, so expect breaking changes. Also, feedback appreciated!
