How do I add Exa to Cursor?

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.exa.ai/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.

Does Exa need an API key?

It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
