FAQ from DuckDuckGo MCP Server

What does the server do?

It provides a Gradio web interface that searches DuckDuckGo and returns results formatted as Markdown. It can optionally summarize content using an external AI API.

How do I run the server?

Build the Docker image (docker build -t ddg-mcp-server .) and run the container (docker run -p 7860:7860 ddg-mcp-server). The application is then available on port 7860.

What dependencies does it require?

The application runs on Python 3.10 and uses Gradio, the DuckDuckGo Search API, BeautifulSoup4, and Markdownify. For summarization, an OpenAI‑compatible API key is needed.

How do I enable AI summarization?

Set the OPENAI_API_URL and ACCESS_TOKEN environment variables (or use a .env file). The default model is gpt-4.1-turbo, configurable in config.py.

Where does the search data come from?

All search results are fetched live from DuckDuckGo's search API. No local search index or cached data is used.
