Web search, fetching, and deep research for your Pi Agent. Powered by Exa

No API key needed for web search and fetch. Works out of the box, just install it and your agent starts using it.

Free - 1000 requests/month, via the Exa MCP server
Semantic search - understands intent, not just keyword searches
LLM-friendly results - Exa returns clean snippets instead of dumping entire sites that nuke your context window
Get what you want - Your agent can make sense of Exa's multiple search filters to get you narrowed results
