Mcp Exa

2 toolsSTDIOregistry active

Summary

This server connects Claude to Exa's search API without requiring your own API key, which is its main appeal. You get four tools: basic web search, code-specific search that pulls from GitHub and Stack Overflow, URL crawling for full page content, and advanced search with filters. It's a Python package you install via pip and run as a standalone command. Useful when you need Claude to search the web or fetch fresh content during a conversation, especially if you don't want to manage another API key. The code search tool is handy for finding examples when you're stuck on implementation details.
