Tomo ships WebMCP Registry: open index of agent-ready tools across 100K sites

Tomo initially planned to keep this internal but decided to release the WebMCP Registry (wmcp.ai) publicly — an open index of websites that expose real tools to AI agents via WebMCP, like searchflights or addtocart, letting agents call sites directly instead of clicking through them.

The team loaded the top 100,000 sites in real browsers, recorded every registered tool, and re-checks them daily. The index already includes Cloudflare Docs, ChatGPT Learn, OpenAI developer sites, Sentry, Target, DoorDash, Zapier (10 tools), Vercel, and CircleCI, with many Shopify storefronts registering 11 tools each.
