Exa Search

Neural search for web content, code, companies, and people via the Exa MCP server.

When to Activate

• User needs current web information or news
• Searching for code examples, API docs, or technical references
• Researching companies, competitors, or market players
• Finding professional profiles or people in a domain
• Running background research for any development task
• User says "search for", "look up", "find", or "what's the latest on"

MCP Requirement

Exa MCP server must be configured. Add to ~/.claude.json:

"exa-web-search": {
  "command": "npx",
  "args": ["-y", "exa-mcp-server"],
  "env": { "EXA_API_KEY": "YOUR_EXA_API_KEY_HERE" }
}

Get an API key at exa.ai.

crawling_exa(url: "https://example.com/article", tokensNum: 5000)

Parameters:

| Param | Type | Default | Notes | |-------|------|---------|-------| | url | string | required | URL to extract | | tokensNum | number | 5000 | Content tokens |

deep_researcher_start / deep_researcher_check

Start an AI research agent that runs asynchronously.

# Start research
deep_researcher_start(query: "comprehensive analysis of AI code editors in 2026")

# Check status (returns results when complete)
deep_researcher_check(researchId: "<id from start>")

Usage Patterns

Quick Lookup

web_search_exa(query: "Node.js 22 new features", numResults: 3)

Code Research

get_code_context_exa(query: "Rust error handling patterns Result type", tokensNum: 3000)

Company Due Diligence

company_research_exa(companyName: "Vercel", numResults: 5)
web_search_advanced_exa(query: "Vercel funding valuation 2026", numResults: 3)

Technical Deep Dive

# Start async research
deep_researcher_start(query: "WebAssembly component model status and adoption")
# ... do other work ...
deep_researcher_check(researchId: "<id>")

Tips

• Use web_search_exa for broad queries, web_search_advanced_exa for filtered results
• Lower tokensNum (1000-2000) for focused code snippets, higher (5000+) for comprehensive context
• Combine company_research_exa with web_search_advanced_exa for thorough company analysis
• Use crawling_exa to get full content from specific URLs found in search results
• deep_researcher_start is best for comprehensive topics that benefit from AI synthesis
