Turn any REST API into an MCP server. No code required.
APIFold reads an OpenAPI 3.x or Swagger 2.x specification and generates a live, production-ready MCP server endpoint. AI agents — Claude, Cursor, Copilot, or any MCP-compatible client — can connect immediately. Tool calls execute real HTTP requests to real upstream APIs with securely stored credentials. No stubs, no mocks, no glue code.
Quick Start
CLI (fastest)
npx apifold serve ./your-openapi-spec.yaml --base-url https://api.example.comOne command. Your spec becomes a running MCP server with SSE transport on localhost:3000. Connect Claude or Cursor immediately.
From the API Registry
npx apifold serve --registry stripe --base-url https://api.stripe.comShips with 8 pre-configured API specs: Stripe, GitHub, Slack, HubSpot, Twilio, OpenAI, Notion, and Petstore.
Hosted Platform
- Sign up at apifold.dev
