openapi-servers

Why we included this project

These reference servers give developers a working starting point when an agent needs to do something beyond generating text. Each one is a compact FastAPI service that exposes a real capability through the standard OpenAPI spec, so any OpenAPI-compatible client can call it without learning a proprietary protocol. The servers cover file access, Git operations, weather lookup, SQL querying, and even your own RAG pipeline. You can clone a server, strip it down, and run it locally or in the cloud with Docker. Small teams get a ready-made template with sensible security defaults (HTTPS, OAuth, JWT, API keys) and a bridge to MCP if they're migrating between the two tooling worlds.
