mturac Exa Search
Drift-prone skill. Exa MCP tool names, parameters, and account limits can change. Confirm the exposed tool surface and current Exa docs before relying on a specific search mode, category, or livecrawl behavior.
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 ~/.codex.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.

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.

Tips
- Use
web_search_exafor current information, company lookups, and broad discovery - Use search operators like
site:, quoted phrases, andintitle:to narrow results - Lower
tokensNum(1000-2000) for focused code snippets, higher (5000+) for comprehensive context - Use
get_code_context_exawhen you need API usage or code examples rather than general web pages
