Auto-MCP with OpenAPI Integration

This is a custom Auto-MCP server in Python that:

• Dynamically creates MCP tools from an OpenAPI specification
• Handles SSL verification disabling for internal API requests
• Provides smart default values for required parameters
• Exposes tools to MCP-compatible IDEs like Windsurf via HTTP

Features

• Dynamic Tool Registration: Automatically creates MCP tools from OpenAPI endpoints
• Smart Default Values: Generates appropriate default values for required parameters
• SSL Verification Control: Disables SSL verification for internal API requests
• Enhanced Error Handling: Provides structured error responses
• Detailed Logging: Logs API requests and responses for debugging
• Flexible Configuration: Supports environment variables and command-line arguments

Usage

Configuration Priority

The server determines the OpenAPI specification URL in the following order of priority:

1. Command-line argument (--spec)
2. Environment variable (OPENAPI_SPEC_URL)

Note: You must provide an OpenAPI specification URL using one of the above methods.

Basic Usage

1. Install requirements:

pip install -r requirements.txt

Running the Server

1. Run the server with an OpenAPI spec URL:

python main.py --spec https://example.com/api-spec.json

2. Run with custom settings:

python main.py --spec https://example.com/api-spec.json --base-url https://api.example.com --host localhost --port 8084 --path /mcp

3. You can specify additional options:

python main.py --spec path/to/spec.json --base-url https://api.example.com

Development

1. Run tests:

python -m src.tests.test_openapi_loader

2. Modify configuration in src/config/openapi_config.py to customize:

   • Default headers
   • Authentication methods
   • Logging behavior
   • Default parameter values
   • Tool naming conventions
   • Endpoint filtering

3. Configure in your IDE's MCP settings:

{
  "mcpServers": {
    "auto-mcp-python": {
      "url": "http://localhost:8083/mcp"
    }
  }
}

Docker Deployment

You can easily deploy the Auto-MCP server using Docker:

Using Docker Compose (Recommended)

1. Build and start the container:

docker-compose up -d

2. View logs:

docker-compose logs -f

3. Stop the container:

docker-compose down

Using Docker Directly

1. Build the Docker image:

docker build -t auto-mcp-python .

2. Run the container with an OpenAPI spec URL:

docker run -p 8083:8083 -e OPENAPI_SPEC_URL=https://example.com/openapi.json auto-mcp-python

3. Run with additional configuration options:

docker run -p 8083:8083 -e OPENAPI_SPEC_URL=https://your-api-domain.com/openapi.json -e OPENAPI_BASE_URL=https://api.example.com auto-mcp-python

Note: The environment variable OPENAPI_SPEC_URL is required unless you provide a spec URL via command-line arguments.

4. Configure in your IDE's MCP settings to connect to the Docker container:

{
  "mcpServers": {
    "auto-mcp": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://localhost:8083/mcp",
        "--transport",
        "http-only"
      ],
      "env": {
        "OPENAPI_SPEC_URL": "https://your-api-domain.com/openapi.json"
      }
    }
  }
}

Note: The env section in the IDE configuration passes environment variables to the MCP server, allowing you to specify the OpenAPI specification URL without modifying the server code or container.
