DuckDuckGo MCP: Documentation

Updated: 25 July 2026

Connection

Repo: github.com/nickclyde/duckduckgo-mcp-server (1.4k★). Install: uvx duckduckgo-mcp-server (stdio) — SSE/HTTP modes are also supported. No auth needed — the service asks for no key and isn't tied to any account.

Tools

search — web search via DuckDuckGo with a result count and basic filters; fetch_content — extracts readable text from a found page by URL.

Agent flow

"Find a definition for this term in public sources", "compare two sources on a topic and pull out the key points", "fact-check something on the web without a paid search subscription".

Pricing

Completely free — no keys, no pricing tiers, no hard server-side rate limit (DuckDuckGo itself may throttle frequent requests from one IP).

Note

A community project (nickclyde); there's no official DuckDuckGo MCP. Since there's no key, there's no usage metering either — fine for simple tasks, not built for industrial-scale load.
