OpenAPI to MCP

Converts any OpenAPI or Swagger specification into callable tools with zero configuration.

Point at any OpenAPI 3.x or Swagger 2.0 spec URL and it automatically generates callable tools for every API endpoint. Features LLM-optimized flat parameter schemas, built-in authentication (API key, Bearer, OAuth2), automatic retry with exponential backoff, and response truncation for context window efficiency. Supports both stdio and SSE transports.
