The official MCP server from Exa, the search engine built for AI: web search, page crawling/extraction, and research tools exposed over a hosted remote endpoint (or a local stdio server via npx). The strongest option when a Claude agent needs fresh, cited web information beyond the model's training window.

What it does

  • Hosted remote MCP endpoint — no local process to manage, just a URL plus API key
  • Search, crawl/extract, and research tools covering the common web-access needs of an agent
  • Runs locally via npx when you need stdio instead of remote HTTP
  • Built by Exa, whose index is purpose-built for LLM retrieval rather than page rank

When to use it

Best for agents that must ground answers in current web content: competitive research, citation-backed answers, monitoring pages. Pick it over generic search MCPs when result quality and freshness matter more than price.

Getting started

Hosted (recommended):
claude mcp add exa --transport http https://mcp.exa.ai/mcp

Local stdio:
npx exa-mcp-server

Get an API key at exa.ai

Things to know

Search API calls are metered — heavy agent loops can burn quota fast. Results are only as good as the query; teach the agent to reformulate instead of retrying identical queries.
