mcp-api-gateway

Overview

This MCP server acts as a gateway to integrate any REST API with Claude Desktop by automatically converting API endpoints into Claude tools. It uses Swagger/OpenAPI specifications to generate tools dynamically, allowing Claude to interact with APIs without custom integration code. The server supports multiple authentication methods, performance optimization for large APIs, and includes features like automatic retries and cookie-based authentication.
