The Exa MCP Server connects AI agents to Exa’s search infrastructure for web search, content fetching and multi-step research. Released by Exa Labs as an open-source project on GitHub, it has gathered more than 5,100 stars and was actively updated in 2026. Note that this listing covers Exa Labs’ MCP server specifically; it is a distinct project from other similarly named tools listed on Tooloso.
Exa is a search engine built for AI, and this MCP server exposes it to any assistant that speaks the Model Context Protocol. Agents can run web searches tuned for AI consumption, fetch and extract clean content from pages, search code, and carry out deeper multi-step research tasks. You can connect to Exa’s hosted MCP endpoint in seconds or run the server yourself from the open-source code, and it also works as an agent plugin for compatible clients, including installation through the Claude plugin marketplace.
The MCP server is open source under the MIT license. It talks to the Exa API, which offers a free starting allowance with an API key and paid usage beyond that, so the setup is best described as freemium.
The Exa MCP Server is for developers building agents, research assistants and chatbots that need fresh, reliable information from the live web. It is especially useful for teams already working in the MCP ecosystem who want high-quality search and extraction without building their own crawling stack.
