Exa is an MCP server published by ai.exa that provides fast web search and web crawling for agents. It communicates over streamable HTTP transport. Once installed, an agent can use it to run live queries against the web and retrieve page content. The registry description indicates the server includes Exa-code, a context tool for coding. The upstream repository is hosted at exa-labs/exa-mcp-server on GitHub. No environment variables, package identifiers, or tool schemas were listed in the verified registry facts, so setup details beyond the transport type are not available from the source record. This capability is intended for agents that need current information from the internet rather than relying on static training data. It requires a client that supports streamable HTTP. The license and specific version are not recorded in the provided facts. Because the tool list was empty in the facts, the exact names and parameters of the search and crawl interfaces are not known from this record, but the server is described as enabling fast, intelligent web search and web crawling.
