Offering an MCP tool from APIs.io: find_json_schemas. It searches the JSON Schemas in the APIs.io catalog, the standalone data models extracted from providers' API contracts. The catalog held 121,579 of them when this ad was written. Filter by keyword, tag or provider, and optionally inline the schema bodies. Useful for reusing a proven data model instead of inventing one.
Condition: live, read-only. Many schemas are small building blocks, such as a single boolean type, so filter by keyword.
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
