Search and summarize recent news on artificial intelligence startups.

The server handles the query, fetches relevant articles, and provides summaries for easy reference.

🔌 Integration with MCP Clients

To integrate the Exa MCP Server with Claude Desktop, follow these steps:

1. Open Configuration File: Locate the claude_desktop_config.json file within either application settings or specified directories.
2. Configure MCP Server: Add the configuration entry as shown below:

   {
     "mcpServers": {
       "exa": {
         "command": "npx",
         "args": ["/path/to/exa-mcp-server/build/index.js"],
         "env": {
           "EXA_API_KEY": "your-api-key-here"
         }
       }
     }
   }
   

Replace your-api-key-here with your actual Exa API key.

3. Restart Claude Desktop: Ensure all changes take effect by completely quitting and restarting the application.
