Configuration ⚙️

For Claude Desktop

1. Configure Claude Desktop to recognize the Exa Websets MCP server

You can find claude_desktop_config.json inside the settings of Claude Desktop app:

Open the Claude Desktop app and enable Developer Mode from the top-left menu bar.

Once enabled, open Settings (also from the top-left menu bar) and navigate to the Developer Option, where you'll find the Edit Config button. Clicking it will open the claude_desktop_config.json file, allowing you to make the necessary edits.

OR (if you want to open claude_desktop_config.json from terminal)

For macOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

For Windows:

code %APPDATA%\Claude\claude_desktop_config.json

2. Add the Exa Websets server configuration:

{
  "mcpServers": {
    "exa-websets": {
      "command": "npx",
      "args": ["-y", "exa-websets-mcp-server"],
      "env": {
        "EXA_API_KEY": "your-api-key-here"
      }
    }
  }
}

Replace your-api-key-here with your actual Exa API key from dashboard.exa.ai/api-keys.

For Claude Code

To configure this MCP server with Claude Code, use the following command:

# Install server locally first
npm install -g exa-websets-mcp-server

# Add to Claude Code with environment variable
claude mcp add exa-websets -e EXA_API_KEY=your-api-key-here -- npx exa-websets-mcp-server

# Or if you have built the project locally:
claude mcp add exa-websets -e EXA_API_KEY=your-api-key-here -- node /path/to/exa-websets-mcp-server/build/index.js

After adding the server, you can check its status with:

claude mcp list

Use the /mcp command within Claude Code to verify the server is connected.

3. Restart Claude Desktop

For the changes to take effect:

1. Completely quit Claude Desktop (not just close the window)
2. Start Claude Desktop again
3. Look for the icon to verify the Exa Websets server is connected

Using Prompts 💬

Prompts provide interactive workflows that guide you through complex websets operations. They're especially useful for:

• Understanding the asynchronous nature of websets
• Learning best practices for different use cases
• Getting step-by-step instructions with example commands

To use a prompt in Claude, simply mention it:

• "Use the quick_start prompt to help me create my first webset"
• "Show me the webset_status_check for webset_abc123"
• "Guide me through enrichment_workflow for my completed webset"

Each prompt provides contextual guidance, example commands, and best practices tailored to your specific situation.

Using via NPX

Run the server directly with npx:

# Run the websets server
npx exa-websets-mcp-server

Troubleshooting 🔧

Common Issues

1. Server Not Found

   • Verify the npm package is correctly installed
