Usage

Quickstart with Claude Desktop

1. Get your API key from HeyGen.
2. Install uv package manager (see Installing uv section above).
3. Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include the following:

{
  "mcpServers": {
    "HeyGen": {
      "command": "uvx",
      "args": ["heygen-mcp"],
      "env": {
        "HEYGEN_API_KEY": ""
      }
    }
  }
}

If you’re using Windows, you’ll need to enable “Developer Mode” in Claude Desktop to use the MCP server. Click “Help” in the hamburger menu at the top left and select “Enable Developer Mode”.

Available MCP Tools

The server provides the following tools to Claude:

• get_remaining_credits: Retrieves the remaining credits in your Heygen account.
• get_voices: Retrieves a list of available voices from the Heygen API (limited to first 100 voices).
• get_avatar_groups: Retrieves a list of Heygen avatar groups.
• get_avatars_in_avatar_group: Retrieves a list of avatars in a specific Heygen avatar group.
• generate_avatar_video: Generates a new avatar video with the specified avatar, text, and voice.

Development

Running with MCP Inspector

To run the server locally with the MCP Inspector for testing and debugging:

uv --with "mcp[cli]" dev heygen_mcp/server.py

This will start the server in development mode and allow you to use the MCP Inspector to test the available tools and functionality.
