mcp-openapi converts any OpenAPI/Swagger spec into MCP tools for Claude, Cursor, and Windsurf. Just provide a URL — no config files, no boilerplate code. Supports Swagger 2.0, OpenAPI 3.x, built-in auth, and flat parameter schemas for better LLM accuracy. 800+ weekly npm downloads.
Hey PH! I built mcp-openapi because I was tired of writing MCP server boilerplate for every API I wanted Claude to use. Now it's one command: `npx mcp-openapi https://your-api-spec.json`. It handles auth, flattens nested schemas so LLMs don't hallucinate, and works with Claude Desktop, Cursor, and Windsurf. Would love to hear what APIs you'd connect first!
