# Exa MCP Server Exa MCP gives you real-time web searches and can extracts content from any URL. It also finds the best code examples and documentation, searches billions of GitHub repos, docs sites, and StackOverflow to give you fresh coding context. **Tools observed.** Pod connected on 2026-08-31 and the server listed 2 tools directly. Verified. Categorised under [developer-tools](/mcp/for/developer-tools). Published by [exa.ai](https://exa.ai/). ## Status Pod connected to Exa on 2026-08-31. It answered and listed its tools, responding in 412ms. It identifies itself as `exa-search-server` version 3.2.1, speaking streamable-http. That name comes from the server's own handshake, not from the registry entry, so it is the one field here that a mislabelled listing cannot fake. ### Claim mismatch Registry lists get_code_context_exa; the live server exposes web_fetch_exa instead. ## Connect A hosted endpoint at `https://mcp.exa.ai/mcp`, over streamable-http. Nothing to install. ```json { "mcpServers": { "exa-2": { "type": "http", "url": "https://mcp.exa.ai/mcp" } } } ``` ## Known issues **89 problems reported by people outside the maintainer team.** Issues filed by the project's own owners, members and collaborators are excluded — those are release checklists and internal refactors, not things that will go wrong for you.

Claude Code can therefore keep an older `3.3.10` cache indefinitely. 2. The plugin MCP URL is fixed to `https://mcp.exa.ai/mcp?client=claude-code-plugin`.
