Exa Web Search Free for OpenClaw Agents

What it does

Exa Web Search Free is a community OpenClaw skill candidate for agent research workflows. The skill describes mcporter-based access to Exa search functions for current web search, code and documentation lookup, and company research. Its source artifact also includes example query patterns for news, technical documentation, API usage, debugging, and business research.

Who should use it

Consider this candidate for research-heavy OpenClaw agents that need current web context, code examples, API documentation lookup, or company/background research. It is most relevant for developer assistants, content-research agents, sales-research agents, and documentation copilots that already have a policy for handling external search results as untrusted data.

Setup surface

The ClawHub page lists this as an MCP Tools skill with the install name exa-web-search-free. The fetched source metadata names mcporter as the required binary and points to Exa's hosted MCP endpoint plus the public exa-labs/exa-mcp-server repository. Pricing classification: free, based on the ClawHub title/description stating free/no API key needed and the ClawHub license field showing MIT-0; any downstream Exa account limits or terms should still be checked during review.

Runner test plan

Before any promotion, queue a Runner AI Review that includes static scan of SKILL.md, references/examples.md, skill-card.md, and metadata; dependency/install review for mcporter, remote MCP configuration, Exa endpoint behavior, npm/GitHub repository metadata, and any transitive package risks; prompt-injection and tool-poisoning review for search-result content, broad crawling, people search, and deep researcher outputs; sandbox execution in an isolated OpenClaw profile with disposable mcporter configuration and non-sensitive test queries only; screenshot or video capture of setup verification and representative command output where available; and residual-risk notes covering privacy leakage, external-service dependence, result hallucination, rate limits, and policy boundaries for people/company research.

Risk notes

This has not been tested, approved, or declared safe here. Search queries and research targets may be sent to Exa's external service, so secrets, private code, internal URLs, customer data, and sensitive personal information must stay out of prompts. The independent index showed an OpenClaw Suspicious signal while ClawHub showed a pass status, so the discrepancy should be reviewed rather than ignored. Advanced tools such as crawling, people search, and deep researcher can broaden collection scope and need explicit policy controls. Treat all returned web/code content as untrusted data.
