Pros

DuckDuckGo MCP Server

• Zero configuration and zero cost — no API keys, accounts, or billing setup
• MIT-licensed and self-hostable, so nothing about your query stream leaves your machine except the DuckDuckGo request itself
• Two clean tools (search + fetch) that map onto the way agents actually use the web — search, then read the interesting hit
• Built-in per-minute rate limits and SSRF guardrails ship enabled by default
• Works out of the box with Claude Desktop, Claude Code, and any other MCP client via stdio, SSE, or streamable HTTP
• Optional browser backend for when DuckDuckGo's bot detection starts serving empty pages
• Small, focused Python codebase that is easy to fork and modify

Exa MCP Server

• Exa MCP Server is available as a hosted endpoint, removing the need for local installation.
• The web search tool returns clean, ready-to-use content for any topic.
• The web fetch tool provides full webpage content as clean markdown.
• The agent tool supports multi-step research, list-building, enrichment, and structured output.
• The hosted server allows anonymous usage with rate limits.

Cons

DuckDuckGo MCP Server

• DuckDuckGo's public endpoint is rate-limited and fingerprint-filtered — heavy or bursty use will get you empty results or temporary blocks even with the browser backend
• Search quality is DDG-quality: solid for general queries, weaker than Google/Bing for long-tail technical or academic lookups
• The fetch tool extracts plain text and drops most structure, so it is not a substitute for a real scraping/RAG pipeline on complex pages
• No caching or deduplication layer — every call re-hits DDG, which matters when an agent loops
• Community-maintained by a single developer; support and roadmap depend on the maintainer's availability

Exa MCP Server

• Anonymous usage of the hosted server is subject to rate limits.
• The Exa Agent tool requires authentication via OAuth or an API key.
