What is OpenAPI to MCP Server Generator?

This tool helps developers quickly create a Model Context Protocol (MCP) server that connects Large Language Models (LLMs) with your existing APIs. It automatically converts OpenAPI specifications into a ready-to-use MCP server implementation.

How to use it?

Simply provide your OpenAPI specification (either local file or URL), and the tool will generate all necessary files for an MCP server. Then just install dependencies and start the server.

Use Cases

Ideal for developers who want to: 1) Quickly expose existing APIs to LLMs 2) Create AI-powered API interfaces 3) Build automated API testing tools with LLMs

Key Features

Automatic Tool GenerationConverts each API endpoint in your OpenAPI spec into an MCP tool automatically
Multiple Transport OptionsSupports stdio transport (with SSE support through mcp-proxy)
Complete Project SetupGenerates all necessary files including server implementation, package.json and configuration
Easy ConfigurationSimple environment-based configuration using .env files
Nested $ref SupportSupports nested $ref in OpenAPI specifications

Pros and Cons

Advantages
Saves development time by auto-generating MCP server code
Standardizes API access for LLM integration
Easy to update when API specifications change
Supports common OpenAPI features including security schemes
Limitations
Currently doesn't support OpenID Connect security
OAuth2 support requires manual token handling
Limited to OpenAPI 3.0 specifications
Websocket transport requires additional proxy setup
