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": "<insert-your-api-key-here>"
      }

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.

Development
