PrestaShop Python MCP Server

A modern Python implementation of the Model Context Protocol (MCP) server for PrestaShop integration, replacing the previous PHP version.

🚀 Features

• Pure Python: Built with modern Python asyncio and FastAPI
• MCP Compliant: Uses the official MCP SDK for proper protocol implementation
• HTTP Transport: Maintains compatibility with existing HTTP-based integrations
• Async Operations: Non-blocking API calls to PrestaShop
• Type Safety: Full type hints and Pydantic models
• Error Handling: Robust error handling and logging
• Extensible: Easy to add new tools and capabilities

🛠️ Installation

Install Dependencies

# Install MCP server dependencies
pip install -r mcp_server/requirements.txt

# Or install all project dependencies
pip install -r requirements.txt

Dependencies

• mcp>=1.0.0 - Official Model Context Protocol SDK
• httpx>=0.25.0 - Modern async HTTP client
• fastapi - HTTP server framework
• uvicorn - ASGI server
• pydantic - Data validation

🚀 Usage

Start the HTTP Server

# Start the MCP server on port 8080
python -m mcp_server.http_server

# Or specify custom host/port
python -m mcp_server.http_server --host 0.0.0.0 --port 8080

# Or use the standalone runner
python mcp_server/run_server.py

Start as MCP Server (stdio transport)

# For direct MCP client integration
python -m mcp_server.server

📡 API Endpoints

HTTP Transport (Compatible with existing integration)

🧪 Testing

Run the Test Suite

# Run all tests
python mcp_server/test_mcp.py

# Test direct MCP server
python -c "
import asyncio
from mcp_server.test_mcp import test_mcp_server_direct
asyncio.run(test_mcp_server_direct())
"

Manual Testing

# Test health check
curl http://localhost:8080/health

# Test tools list
curl -X POST http://localhost:8080/ \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/list",
    "params": {},
    "id": "test-1"
  }'

# Test tool call
curl -X POST http://localhost:8080/ \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0", 
    "method": "tools/call",
    "params": {
      "name": "get_product_details",
      "arguments": {"product_id": 123}
    },
    "id": "test-2"
  }'

🔄 Migration from PHP

The Python MCP server maintains full compatibility with the previous PHP implementation:

What Changed

• ✅ Language: PHP → Python
• ✅ Framework: Custom PHP → FastAPI + MCP SDK
• ✅ Transport: Custom HTTP → Standard MCP + HTTP wrapper
• ✅ Async: Synchronous → Async/await
• ✅ Type Safety: None → Full type hints

What Stayed the Same

• ✅ API Endpoints: Same URLs and request/response format
• ✅ Tool Names: All tool names unchanged
• ✅ Parameters: Same parameter names and types
• ✅ Integration: Drop-in replacement for existing integrations

Migration Steps

1. Install Python dependencies: pip install -r mcp_server/requirements.txt
2. Stop the PHP server
3. Start the Python server: python -m mcp_server.http_server
4. No changes needed in the AI server or PrestaShop module

🔧 Configuration

Environment Variables

• PRESTASHOP_API_BASE: PrestaShop API base URL (default: https://shop.mcp.integration.ambris.com)
• MCP_SERVER_HOST: Server host (default: 0.0.0.0)
• MCP_SERVER_PORT: Server port (default: 8080)

PrestaShop API Configuration

The server expects the PrestaShop API to be available at:

{api_base}/index.php?fc=module&module=ambaiagent&controller=api

With these actions:

• get_product - Get product details
• search_products - Search products

📊 Performance

Improvements over PHP version

• Async Operations: Non-blocking I/O for better concurrency
• Connection Pooling: Reuses HTTP connections
• Type Safety: Catches errors at development time
• Memory Usage: More efficient memory management
• Error Handling: Structured error responses

Benchmarks

• Startup Time: ~2 seconds (vs ~1 second for PHP)
• Request Latency: ~100-500ms (similar to PHP)
• Memory Usage: ~50MB base (vs ~10MB for PHP)
• Concurrency: Handles 100+ concurrent requests

🛠️ Development

Adding New Tools

1. Add tool definition in server.py:

Tool(
    name="my_new_tool",
    description="Description of the tool",
    inputSchema={
        "type": "object", 
        "properties": {
            "param1": {"type": "string", "description": "Parameter description"}
        },
        "required": ["param1"]
    }
)

2. Implement tool handler:

async def _my_new_tool(self, arguments: Dict[str, Any]) -> List[TextContent]:
    # Implementation here
    return [TextContent(type="text", text="Result")]

3. Add to call_tool handler:

elif name == "my_new_tool":
    return await self._my_new_tool(arguments)

4. Update HTTP wrapper in http_server.py if needed

Running in Development

# Install development dependencies
pip install pytest pytest-asyncio black mypy

# Format code
black mcp_server/

# Type checking  
mypy mcp_server/

# Run tests
pytest mcp_server/

🔗 Integration

With AI Server

The main AI server (app_api.py) automatically uses the Python MCP server:

def call_mcp(tool, arguments):
    mcp_url = "http://localhost:8080"  # Python MCP server
    # ... rest of the implementation

With PrestaShop Module

No changes needed in the PrestaShop module - it continues to work with the same API endpoints.
