exa-search

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 . This repo's current Exa setup documents the tool surface exposed here: web_search_exa and get_code_context_exa . If your Exa server exposes additional tools, verify their exact names before depending on them in docs or prompts. Core Tools web_search_exa General web search for current information, news, or facts. web_search_exa(query: "latest AI developments 2026", numResults: 5) Parameters: Param Type Default Notes query string required Search query numResults number 8 Number of results type string auto Search mode livecrawl string fallback Prefer live crawling when needed category string none Optional focus such as company or research paper get_code_context_exa Find code examples and documentation from GitHub, Stack Overflow, and docs sites. get_code_context_exa(query: "Python asyncio patterns", tokensNum: 3000) Parameters: Param Type Default Notes query string required Code or API search query tokensNum number 5000 Content tokens (1000-50000) 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 or People Research web_search_exa(query: "Vercel funding valuation 2026", numResults: 3, category: "company") web_search_exa(query: "site:linkedin.com/in AI safety researchers Anthropic", numResults: 5) Technical Deep Dive web_search_exa(query: "WebAssembly component model status and adoption", numResults: 5) get_code_context_exa(query: "WebAssembly component model examples", tokensNum: 4000) Tips Use web_search_exa for current information, company lookups, and broad discovery Use search operators like site: , quoted phrases, and intitle: to narrow results Lower tokensNum (1000-2000) for focused code snippets, higher (5000+) for comprehensive context Use get_code_context_exa when you need API usage or code examples rather than general web pages
