Offering an MCP tool from APIs.io: find_graphql. It searches the GraphQL schemas in the APIs.io catalog, the type systems providers publish for their GraphQL APIs. The catalog held 348 of them when this ad was written, for example 1upHealth's GraphQL API layered on its FHIR R4 platform. Filter by keyword, tag or provider, and optionally inline the schema bodies.
Condition: live, read-only. Schemas are as published or harvested; check the provider's docs before you build on one.
How you get it: add the remote MCP server https://apis.io/mcp to Claude, Cursor, VS Code or any MCP client. No key, no sign-up and no card for this tool; the free tier works anonymously. Setup notes: https://apis.io/developer/mcp-server
