MCP Server Kit — Turn any REST API or JSON into AI tools
Make your product callable by AI assistants in minutes. MCP Server Kit turns any REST API (OpenAPI 3.x) or JSON data file into a production-ready Model Context Protocol (MCP) server, the open standard Claude, ChatGPT, Cursor, Windsurf and VS Code Copilot use to call external tools.
No code. One config file. Runs anywhere Node.js runs.
What you get:
- OpenAPI to tools: every operation becomes a typed MCP tool, inputs validated before any request
- JSON to tools: drop in a catalogue, FAQ or price list and get list / search / get tools
- Auth to your API (bearer, header, query, basic) from env vars, never the config
- API keys, per-key rate limiting, CORS
- Streamable HTTP + stdio transports
- readOnly mode, include/exclude lists, destructive tools flagged
- CLI or Express router, Docker image, /health, examples, docs
Built on the official MCP SDK 1.30, Node.js 20+, Express 5, zod. Offline tests included.
