FAQ from DuckDuckGo Search MCP Server

What does this server do?

It provides two tools: search to query DuckDuckGo and return formatted results, and fetch_content to retrieve and clean webpage text.

How do I install and run it?

Use uvx duckduckgo-mcp-server in your terminal, or add it to your MCP client configuration with the command uvx duckduckgo-mcp-server.

How can I configure SafeSearch or default region?

Set the environment variables DDG_SAFE_SEARCH (STRICT, MODERATE, OFF) and DDG_REGION (e.g., us-en, cn-zh) in the server startup configuration.

What is the backend for bypassing bot detection?

The server supports an optional curl backend via the [browser] extra that impersonates Chrome’s TLS handshake. Use --fetch-backend or --search-backend flags to enable it.

Which transport protocols are supported?

The default transport is stdio. You can also run with --transport sse or --transport streamable-http and optionally set --host and --port.
