At a glance: nickclyde/duckduckgo-mcp-server — 913 stars, Python, MIT, v0.1.2. 2 tools: search (up to 10 results, regional filtering) and fetch_content (webpage text extraction). No API key, no signup, no cost. Rating: 3.5/5.
What It Does
| Tool | Description |
|---|---|
search |
Search DuckDuckGo. Returns titles, URLs, descriptions. Configurable max results and region. |
fetch_content |
Fetch and parse a webpage URL. Returns cleaned text stripped of ads and markup. |
Two tools. Compare to Brave Search MCP's six (web, local, image, video, news, summarizer). DuckDuckGo gives you essentials for free; Brave gives breadth for money.
The Free Question
| Server | Cost | API Key | Search Index |
|---|---|---|---|
| DuckDuckGo MCP | Free | No | Bing (via DDG) |
| Brave Search MCP | $5/1K queries | Yes | Brave's independent index |
| Tavily MCP | $0.01/query | Yes | Proprietary (AI-optimized) |
| Exa MCP | $0.005/query | Yes | Neural search |
DuckDuckGo is the only option requiring absolutely nothing. But it uses the duckduckgo-search Python library which scrapes DDG's HTML endpoint — no official API, no SLA, rate limits from bot detection.
Rate Limits & Safety
- Search: 30 requests/minute (server-enforced)
- Content fetch: 20 requests/minute
- SafeSearch: Admin-controlled via environment variable — agents cannot override content filtering
-
Region: Configurable per-request (
us-en,jp-ja,de-de, etc.)
DuckDuckGo's own bot detection is the harder constraint. Heavy automated use from a single IP can trigger CAPTCHAs or temporary blocks.
Setup
# Claude Code
claude mcp add ddg-search uvx duckduckgo-mcp-server
# Or with environment variables
DDG_SAFE_SEARCH=STRICT DDG_REGION=us-en uvx duckduckgo-mcp-server
Supports stdio, SSE, and Streamable HTTP transports.
The Ecosystem
Nick Clyde's server (913 stars) is the clear leader. Alternatives: zhsama (71 stars, TypeScript, single search tool), gianlucamazza (13 stars, adds related suggestions), several others with under 5 stars.
DuckDuckGo vs. Brave — Which One?
Choose DuckDuckGo if you need basic search for personal projects, prototyping, or occasional use without API key management.
Choose Brave if you need reliable production search, specialized types (images, local, news), higher throughput, or an independent search index.
Choose Tavily/Exa if you want results specifically optimized for AI consumption.
Bottom Line
Rating: 3.5/5 — The best free search MCP. Zero friction, content fetching included, admin-locked SafeSearch, three transports, active maintenance. Loses points for only 2 tools (no image/news/local search), scraping fragility (no official API backing), rate limit ceiling, and alpha status. For light search needs, the obvious choice. For production, $5/1K queries for Brave is cheap insurance.
