API 200 is an open source API gateway to simplify 3rd-party integrations. Import endpoints, set up caching, retries, and mocks. Access all services
Connect Api200 to Claude, Cursor or any other MCP client and it stops being a tab you switch to. API 200 is an open source API gateway to simplify 3rd-party integrations. Import endpoints, set up caching, retries, and mocks. Access all services via one URL. Monitor logs, track errors, and get alerts on API incidents. The api200 mcp server is what makes that connection.
API 200 is all-in-one gateway for managing third-party APIs efficiently. Integrate third-party APIs or setup MCP server in minutes with auto-generated code, docs, auth, caching and error handling – so you can focus on what really matters.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Prerequisites — The Prerequisites tool exposed by this serverInstallation — The Installation tool exposed by this serverConfiguration is passed through the environment: USER_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
This sits in the monitoring and observability group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Api200's toolset — Prerequisites, Installation — is a fair guide to whether it matches your workflow. It is maintained by API-200; worth a glance at recent repository activity before you build anything load-bearing on it.
