Why this exists

AI agents are starting to use the web for people: searching, booking, buying. Most sites make them click through pages built for humans. WebMCP lets a site tell agents exactly what it can do, as tools with names, descriptions and inputs.

WebMCP Registry is where those sites are found. Agents and developers can see which sites expose tools, what the tools do, and whether they still work.

How it stays accurate

Nothing here is self-reported. We load every site in a real browser, crawl its pages, and list only the tools we see it register. Every listing is checked again every 24 hours, and tools that disappear come off. How checks work

Who runs it

WebMCP Registry is built by the team behind Tomo, a personal AI in iMessage. We rely on sites being agent-ready, so we keep this index open and free for everyone.
