91 Exa Web Search Free

Free AI search via Exa MCP. Web search for news/info, code search for docs/examples from GitHub/StackOverflow, company research for business intel. No API ke...

Security Scan

The skill's requirements and runtime instructions are coherent with a web/code/company search tool, but it relies on an external mcporter binary and remote Exa MCP service—review those before use.

Purpose & Capability

Name/description (web, code, company search) match the SKILL.md usage. Requiring the mcporter binary is expected because all runtime commands are mcporter calls. Minor metadata mismatch: _meta.json ownerId and version differ from registry metadata; this is an inconsistency in packaging but does not by itself contradict the claimed purpose.

Instruction Scope

SKILL.md instructs the agent to run mcporter commands that configure a remote endpoint (https://mcp.exa.ai/mcp) and then call search/crawl/research tools. That is consistent with a search skill, but these calls will send queries (and, for crawling tools, page contents or URLs) to the external Exa MCP service. The skill also documents people search and crawling tools which can return or process personal/proprietary data — expected for this domain but a privacy/data-exfiltration risk depending on what you send.

Install Mechanism

Instruction-only skill with no install spec and no code files. Nothing in the skill will be written to disk by the package itself. The only runtime requirement is an existing mcporter binary (no instructions here on how to obtain or validate it).

Credentials

No environment variables, credentials, or config paths requested. The absence of secrets is proportional to the described functionality.

Persistence & Privilege

always:false (default) and the skill is user-invocable. It can be invoked autonomously by the agent (platform default); there is no elevated persistence requested and the skill does not modify other skills' configs in its instructions.

Assessment

This skill is internally consistent with a web/code/company search tool, but before installing: (1) verify the origin and integrity of the mcporter binary you will run—mcporter will send data to whatever MCP endpoints you configure; (2) understand that mcporter config add points to https://mcp.exa.ai/mcp, and mcporter call will transmit your queries (and for crawling tools, page contents) to that remote service—do not send secrets, private code, or sensitive documents unless you trust Exa MCP; (3) avoid using the crawling/people_search/deep_researcher tools on proprietary or personal data if you are concerned about exposure; (4) note the small packaging metadata mismatch (ownerId/version) and consider confirming the publisher if provenance matters. If you cannot validate mcporter or the Exa service, treat this as untrusted remote execution and do not use it with sensitive inputs.

Exa Web Search (Free)

Neural search for web, code, and company research. No API key required.

Setup

Verify mcporter is configured:

mcporter list exa

If not listed:

mcporter config add exa https://mcp.exa.ai/mcp

Core Tools

web_search_exa

Search web for current info, news, or facts.

mcporter call 'exa.web_search_exa(query: "latest AI news 2026", numResults: 5)'

Parameters:

• query - Search query
• numResults (optional, default: 8)
• type (optional) - "auto", "fast", or "deep"

get_code_context_exa

Find code examples and docs from GitHub, Stack Overflow.

mcporter call 'exa.get_code_context_exa(query: "React hooks examples", tokensNum: 3000)'

Parameters:

• query - Code/API search query
• tokensNum (optional, default: 5000) - Range: 1000-50000

company_research_exa

Research companies for business info and news.

mcporter call 'exa.company_research_exa(companyName: "Anthropic", numResults: 3)'

Parameters:

• companyName - Company name
• numResults (optional, default: 5)

Advanced Tools (Optional)

Six additional tools available by updating config URL:

• web_search_advanced_exa - Domain/date filters
• deep_search_exa - Query expansion
• crawling_exa - Full page extraction
• people_search_exa - Professional profiles
• deep_researcher_start/check - AI research agent

Enable all tools:

mcporter config add exa-full "https://mcp.exa.ai/mcp?tools=web_search_exa,web_search_advanced_exa,get_code_context_exa,deep_search_exa,crawling_exa,company_research_exa,people_search_exa,deep_researcher_start,deep_researcher_check"

# Then use:
mcporter call 'exa-full.deep_search_exa(query: "AI safety research")'

Tips

• Web: Use type: "fast" for quick lookup, "deep" for thorough research
• Code: Lower tokensNum (1000-2000) for focused, higher (5000+) for comprehensive
• See examples.md for more patterns
