Overview
Exa is a developer platform for agent-oriented web search and crawling. Its API can retrieve web results, page contents, highlights, and structured outputs, with search modes for general retrieval, deep research, and other application workflows. Developers use Exa through hosted APIs and official client libraries, including Python and JavaScript examples in the documentation. The company also publishes an official MCP server for connecting compatible AI clients to Exa search and crawling. The core hosted product is not open source, so the MCP repository is listed as related rather than as the product repository.
