MCPO: A Simple, Secure MCP to OpenAPI Proxy Server

⚡️ Project Profile

Open WebUI MCPO is a simple and secure MCP-to-OpenAPI proxy server that quickly converts any MCP tool into an OpenAPI-compatible HTTP server. This project was developed by the Open WebUI team and currently has 1.9k starred tags on GitHub, showing its popularity in the developer community.

🌟 Core functions

1. protocol conversion: Convert the MCP server's command line interface to a standard RESTful OpenAPI interface
2. Multi-protocol support: Compatible with SSE (Server-Sent Events) and Streamable HTTP protocols.
3. One-Click Deployment: Support for rapid deployment via Python, uv or Docker
4. Multi-tool management: Simultaneous management of multiple MCP tools via configuration files
5. Automatic Document Generation: automatically generate interactive API documentation for each tool

🎯 Suitable for the crowd

• Developers who need to integrate MCP tools into existing systems
• Technical teams looking to add standard API interfaces to AI tools
• Operations staff who need to ensure secure communication between tools
• Startups that want to streamline the process of deploying AI tools

🔍 Principle of operation

MCPO works as an intermediate agent layer:

1. Receive standard HTTP/OpenAPI requests
2. Convert to MCP protocol to communicate with back-end tools
3. Converts the tool response back to OpenAPI format and returns the

🛠️ Usage

Basic use

uvx mcpo --port 8000 --api-key "your-key" -- your_mcp_server_command

The Docker Way

docker run -p 8000:8000 ghcr.io/open-webui/mcpo:main --api-key "your-key" -- your_mcp_server_command

Configuration file method

{ "mcpServers": { "memory": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"] } }}

💡 Program Advantages

1. Standardized interfaces: Make MCP tools immediately compatible with all OpenAPI tools and SDKs
2. Enhanced Security: Replacing the original stdio communication with HTTP is more secure and reliable.
3. Zero Configuration Documentation: automatically generates complete API documentation for each tool
4. Development Friendly: Support Python 3.8+, provide perfect development and testing process
5. Community Support: active open source community, continuously updated and maintained
