Q&A

Will the server work with websites that block the default httpx client?

No; sites that block the default httpx client may not be reachable. You may need to adjust the client settings or use a different fetching method, but the out‑of‑the‑box server may fail on such sites.

Asked by Jasper Vermeer · Mar 9, 2026

Which client tools are supported, and how do I set up the server with Claude Desktop?

The server works with Claude Desktop and Claude Code. For Claude Desktop, add a ddg search entry in claude_desktop_config.json with the command uvx duckduckgo mcp server; optionally include the SafeSearch and region env variables as shown in the README.

Asked by Yara Mansour · Mar 8, 2026

What rate‑limiting features does the server provide for searches and content fetching?

The server includes built‑in protection that enforces limits on both DuckDuckGo search requests and webpage fetches, preventing you from hitting DuckDuckGo’s public rate caps and ensuring stable operation for LLM integrations.

How do I configure SafeSearch and region settings for the DuckDuckGo MCP server?

Add environment variables in the MCP server config: set DDG_SAFE_SEARCH to STRICT, MODERATE, or OFF, and set DDG_REGION to a region code like us‑en or cn‑zh. These values are passed in the env section of the Claude Desktop or Claude Code configuration JSON.
