README

OpenAPI to MCP Generator (openapi-mcp-generator)

Generate Model Context Protocol (MCP) servers from OpenAPI specifications.

This CLI tool automates the generation of MCP-compatible servers that proxy requests to existing REST APIs—enabling AI agents and other MCP clients to seamlessly interact with your APIs using your choice of transport methods.

✨ Features

🔧 OpenAPI 3.0 Support: Converts any OpenAPI 3.0+ spec into an MCP-compatible server.
🔁 Proxy Behavior: Proxies calls to your original REST API while validating request structure and security.
🔐 Authentication Support: API keys, Bearer tokens, Basic auth, and OAuth2 supported via environment variables.
🧪 Zod Validation: Automatically generates Zod schemas from OpenAPI definitions for runtime input validation.
⚙️ Typed Server: Fully typed, maintainable TypeScript code output.
🔌 Multiple Transports: Communicate over stdio, SSE via Hono, or StreamableHTTP.
🧰 Project Scaffold: Generates a complete Node.js project with tsconfig.json, package.json, and entry point.
🧪 Built-in HTML Test Clients: Test API interactions visually in your browser (for web-based transports).

🚀 Installation

npm install -g openapi-mcp-generator

You can also use yarn global add openapi-mcp-generator or pnpm add -g openapi-mcp-generator

🛠 Usage

# Generate an MCP server (stdio)
openapi-mcp-generator --input path/to/openapi.json --output path/to/output/dir

# Generate an MCP web server with SSE
openapi-mcp-generator --input path/to/openapi.json --output path/to/output/dir --transport=web --port=3000

# Generate an MCP StreamableHTTP server
openapi-mcp-generator --input path/to/openapi.json --output path/to/output/dir --transport=streamable-http --port=3000

CLI Options

`--input`	`-i`	Path or URL to OpenAPI specification (YAML or JSON)	Required
`--output`	`-o`	Directory to output the generated MCP project	Required
`--server-name`	`-n`	Name of the MCP server (`package.json:name`)	OpenAPI title or `mcp-api-server`
`--server-version`	`-v`	Version of the MCP server (`package.json:version`)	OpenAPI version or `1.0.0`
`--base-url`	`-b`	Base URL for API requests. Required if OpenAPI `servers` missing or ambiguous.	Auto-detected if possible
