Mcp Openapi Proxy

Turns any OpenAPI specification into callable MCP tools by dynamically mapping REST endpoints to functions. Point it at Slack, Fly.io, Notion, or your own API spec and immediately get structured tools for every endpoint. Handles authentication through Bearer tokens or custom headers, supports payload-based auth for APIs like Slack, and includes filtering to expose only the endpoints you need. Perfect when you want to quickly integrate existing REST APIs into Claude workflows without writing custom MCP servers for each service.
