What it does
Exa MCP Server connects an assistant to Exa, a web search engine and API. By default it gives two tools: web search that returns clean, ready-to-use page content, and a fetch tool that reads one or more URLs and returns their full text as markdown. Two more tools can be switched on through the tools parameter on the server URL: an advanced search with filters for domains, dates, highlights, summaries and subpage crawling, and agent_run, which starts an Exa Agent for multi-step research, list-building, enrichment and structured output.
Exa runs a hosted server at https://mcp.exa.ai/mcp over streamable HTTP. It works without sign-in at rate-limited levels; for higher limits and for Exa Agent you sign in to Exa with OAuth or pass an Exa API key as a header or URL parameter. The same server is also published as the npm package exa-mcp-server, which runs locally over stdio with an EXA_API_KEY.
The repository also ships Agent Skills and plugins for Claude, Codex and ChatGPT that load the same tools.
