Exa Search

This gives Claude semantic search capabilities through the Exa API, which is fundamentally different from keyword matching. You'd reach for this when you need to find conceptually similar content, search by entity type like companies or research papers, or do embeddings-based discovery instead of traditional search. The setup is straightforward: install it globally, drop in your Exa API key, and use it conversationally. It's community-maintained by BenedictKing and pairs well with other research tools like Tavily or Firecrawl if you're building out a full research workflow. The documentation is light, so expect to reference the GitHub repo for real examples and troubleshooting.
