Exa

Exa MCP Server connects AI agents and coding assistants to Exa's web search and content tools through the Model Context Protocol. It lets an agent search the web, read the full content of pages as clean markdown, and run multi-step research.

The server is hosted at https://mcp.exa.ai/mcp. Developers can connect to it from clients such as Claude, Codex, ChatGPT, Gemini CLI, Windsurf, Zed and Warp, either through a plugin or by adding the URL to a standard mcpServers configuration. The repository is published on GitHub under the MIT licence, and an npm package is also available.

By default the server offers two tools. web_search_exa searches the web for a topic and returns content ready for use, and web_fetch_exa reads one or more URLs as markdown. Optional tools add advanced search with filters for domains and dates, subpage crawling, and agent_run, which runs an Exa Agent for multi-step research, list-building and structured output. Tools are enabled by appending a tools parameter to the URL.

An optional dynamicHighlights setting returns highlights chosen across all results under one shared budget, so less text reaches the agent's context.

The hosted server works without signing in, with rate limits. For higher limits and access to Exa Agent, users sign in with OAuth or pass an Exa API key in the URL, a header or an x-api-key header. The page does not state a price for the server itself.

The project is aimed at developers and teams building AI agents and tools that need current web information. Its repository includes Agent Skills named search and exa-agent for deep research, lead generation and competitive analysis.
