DuckDuckGo Search MCP
DuckDuckGo Search MCP is the community-built privacy-first search server, and the architectural priorities show. Rate limiting is built in for both search and content fetching, keeping the agent within DuckDuckGo's tolerance and the operator's IP outside the block list. Search results are formatted specifically for LLM consumption, in clean text form. Content fetching includes intelligent text extraction so when the agent follows a search result to read a page, the response arrives as parsed markdown. The standout feature is configurability with anonymous access: SafeSearch level (`STRICT`, `MODERATE`, `OFF`) and default region (`us-en`, `cn-zh`, `jp-ja`, etc.) configure via env vars, no API key required. The trade-off is DuckDuckGo's results quality: for general web search, DuckDuckGo's index is solid but smaller than Google's, so research-intensive workflows may want a paid search MCP alongside this one. For agents that need fast, privacy-respecting search out of the box, this is the editorial pick.
