Setup

Basic Setup

1. Activate the virtual environment:

   source venv/bin/activate

1. Install dependencies:

   pip install -r requirements.txt

1. Run the application:

   python main.py

Or alternatively:

   uvicorn main:app --reload

MCP Integration Setup

For AI assistant integration with Gemini CLI:

1. Start both services (FastAPI app + MCP server):

   ./start_services.sh

1. Configure Gemini CLI by adding to your Gemini config:

   {
     "mcpServers": {
       "todo-mcp-server": {
         "command": "/path/to/your/project/venv/bin/python",
         "args": ["mcp_server.py"],
         "cwd": "/path/to/your/project"
       }
     }
   }

1. Test with Gemini CLI:

• "Show me all my todos"
• "Create a new todo called 'Learn FastAPI'"
• "Mark todo as complete"
• "What's my completion rate?"

See MCP_INTEGRATION_GUIDE.md for detailed setup instructions.
