Exa Web Search (Free)

**Quick judgment:** Solid, high-utility search skill that brings Exa’s neural search into an MCP/OpenClaw environment without an API key. Very useful for up-to-date web research, code examples, and business intel, with optional advanced tools for deeper workflows. **Strengths & fit:** - Good coverage of common assistant needs: general web search, code search, and company research. - Optional advanced configuration (`exa-full`) unlocks deep search, crawling, people search, and an AI research agent, making it suitable for more serious research pipelines. - Clear mcporter-based setup and usage examples lower friction for technically inclined users. **Key risks / limitations:** - **External dependency:** Fully dependent on Exa’s MCP endpoint; outages, rate limits, or policy changes will directly impact reliability. - **Unfiltered web content:** Results may contain biased, incorrect, or unsafe material; downstream applications must implement their own validation and safety layers. - **Privacy considerations:** All queries and context sent to the tool are transmitted to an external service; not appropriate for highly sensitive or confidential data without additional safeguards. - **Config complexity for advanced tools:** Accessing the richer tool set requires changing the MCP config URL (`exa-full`), which adds a small layer of operational complexity. **Recommended scenarios:** - Assistants that need **live web access** for news, factual updates, and non-static information. - **Developer-focused** assistants that frequently look up code patterns, library usage, and Stack Overflow/GitHub examples. - **Research, sales, and strategy** workflows that benefit from quick company/people intel and high-relevance search over the open web. - As a **general-purpose web search backbone** in OpenClaw projects where a free, keyless, but external search provider is acceptable and where the host system can handle content validation and safety on top.
