What is the Api To MCP Server?

Generates MCP tool code from OpenAPI specs

What the server does

A tool that creates MCP (Model Context Protocol) servers from OpenAPI/Swagger specifications, enabling AI assistants to interact with your APIs. Create your own branded and customized MCPs for specific APIs or services.

This project creates a dynamic MCP server that transforms OpenAPI specifications into MCP tools. It enables seamless integration of REST APIs with AI assistants via the Model Context Protocol, turning any API into an AI-accessible tool.

  • Dynamic loading of OpenAPI specs from file or HTTP/HTTPS URLs
  • Support for OpenAPI Overlays loaded from files or HTTP/HTTPS URLs
  • Customizable mapping of OpenAPI operations to MCP tools
  • Advanced filtering of operations using glob patterns for both operationId and URL paths
  • Comprehensive parameter handling with format preservation and location metadata
  • API authentication handling
