Exa MCP exposes the following tools to your AI agent: `_ping`, `search`, `get_contents`, `find_similar`, `search_and_contents`. Use these to automate exa workflows directly from Claude, Cursor, or any MCP-compatible client.
Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-exa": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-exa"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.
In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-exa", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-exa"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.
Yes. Exa requires authentication. Check the MCP's documentation for the required credentials.
