MCP Settings Configuration

Add the server to your MCP settings file (typically claude_desktop_config.json or similar):

{
  "mcpServers": {
    "heygen": {
      "command": "node",
      "args": [
        "/path/to/mcp-servers/heygen/dist/index.js"
      ],
      "env": {
        "HEYGEN_API_KEY": "your_api_key_here"

Or using npx (no installation required):

{
  "mcpServers": {
    "heygen": {
      "command": "npx",
      "args": ["heygen-mcp-server"],
      "env": {
        "HEYGEN_API_KEY": "your_api_key_here"
      }
