🚀 Getting Started

Prerequisites

• Python 3.10+

▶️ Running the MCP Server

Start the server

python server.py

By default it runs at:

HOST: 0.0.0.0
PORT: 9393

Override with environment variables:

export HOST_ADDRESS=127.0.0.1
export HOST_PORT=8080
python server.py

🐳 Running with Docker Compose

make dev-compose

Stop the environment:

make dev-down

HOST_PORT=8080 HOST_ADDRESS=127.0.0.1 python server.py

🧑‍💻 Development

Initialize local venv:

make init

Clean development environment:

make clean

🐞 Troubleshooting

I get DuckDuckGo throttling errors

DuckDuckGo sometimes rate-limits requests. Try:

• Slower request frequency
• Changing IP
• Avoiding rapid repeated queries

GitHub returns 403

GitHub rate-limits unauthenticated requests. Wait for reset or reduce frequency.
