HeyGen MCP Server

⚠️ Disclaimer: This is a community fork of the original HeyGen MCP server, which appears to be abandoned. This is not an official HeyGen repository. Use at your own discretion.

Generate AI Videos with Natural Language - A Model Context Protocol (MCP) server for HeyGen API integration with AI assistants.

The HeyGen MCP server enables AI assistants (GitHub Copilot, Claude, ChatGPT) to generate AI avatar videos, manage templates, and work with assets through natural language commands.

🚀 Quick Start (1 Minute)

Requirements: Python 3.10+ | HeyGen API Key (get one here - 10 free credits/month)

⭐ Recommended: VS Code Extension (One-Click Setup)

Fastest way to get started - everything configured automatically:

Install from VS Code Marketplace →

The extension handles server registration and API key configuration automatically!

Installation

Prerequisites

• Python 3.10 or higher
• A Heygen API key (get one from Heygen). Includes 10 Free Credits per Month

Install from PyPI

Install the package directly using pip or uv:

# Using pip
pip install heygen-mcp-sbroenne

# Using uv (recommended)
uv pip install heygen-mcp-sbroenne

# Or run directly without installing (uvx)
uvx heygen-mcp-sbroenne

Install from GitHub Releases

Download pre-built packages from GitHub Releases:

1. Download the .whl or .tar.gz file from the latest release
2. Install with pip:

   pip install heygen_mcp_sbroenne-*.whl
   

For the VS Code extension, download the .vsix file and install via:

• VS Code → Extensions → ... menu → "Install from VSIX..."

Usage

VS Code Extension (Recommended)

The easiest way to use HeyGen MCP with VS Code is through the community VS Code extension:

1. Install the extension:

   • Install from VS Code Marketplace →
   • Or search for "sbroenne.heygen-mcp" in VS Code Extensions (Ctrl+Shift+X)

2. Configure your API key:

   • Use Command Palette (Ctrl+Shift+P)
   • Search for "HeyGen: Configure API Key"
   • Enter your API key

3. Start using it:

   • The HeyGen MCP server will automatically be available to your AI assistant
   • Ask your AI assistant to generate videos, manage templates, etc.

See vscode-extension/README.md for more details.

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:

{
  "inputs": [
    {
      "id": "heygen-api-key",
      "type": "promptString",
      "description": "HeyGen API Key",
      "password": true
    }
  ],
  "mcpServers": {
    "HeyGen": {
      "command": "uvx",
      "args": ["heygen-mcp-sbroenne"],
      "env": {
        "HEYGEN_API_KEY": "${input: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".

Using with VS Code (Manual Configuration)

Add the following to your VS Code settings (.vscode/mcp.json):

{
  "inputs": [
    {
      "id": "heygen-api-key",
      "type": "promptString",
      "description": "HeyGen API Key",
      "password": true
    }
  ],
  "servers": {
    "HeyGen": {
      "type": "stdio",
      "command": "uvx",
      "args": ["heygen-mcp-sbroenne"],
      "env": {
        "HEYGEN_API_KEY": "${input:heygen-api-key}"
      }
    }
  }
}

Using a Local Development Version

If you want to run from a local clone (for development or testing), use uv run instead of uvx:

{
  "inputs": [
    {
      "id": "heygen-api-key",
      "type": "promptString",
      "description": "HeyGen API Key",
      "password": true
    },
    {
      "id": "heygen-mcp-path",
      "type": "promptString",
      "description": "Path to local heygen-mcp repository"
    }
  ],
  "mcpServers": {
    "HeyGen": {
      "type": "stdio",
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "${input:heygen-mcp-path}",
        "python",
        "-m",
        "heygen_mcp.server"
      ],
      "env": {
        "HEYGEN_API_KEY": "${input:heygen-api-key}"
      }
    }
  }
}

For VS Code, use servers instead of mcpServers.

Available MCP Tools

The server provides 7 resource-based tools, each with multiple actions:

user - User Account Management

voices - Voice Management

avatars - Avatar Management

videos - Video Generation

✨ Video Background Support - Generate videos with color, image, or video backgrounds. See Video Backgrounds Guide for details.

templates - Template Management

assets - Asset Management

folders - Folder Management

Example Usage:

# Get remaining credits
user(action="credits")

# List all avatars
avatars(action="list")

# Get specific avatar details
avatars(action="get", avatar_id="avatar_123")

# Generate a video (single scene)
videos(action="generate", video_inputs_json='[{"character": {"avatar_id": "..."}, "voice": {"voice_id": "...", "input_text": "Hello!"}}]')

Development

Setup

# Clone the repository
git clone https://github.com/sbroenne/heygen-mcp.git
cd heygen-mcp

# Install dependencies
uv sync --dev

# Install pre-commit hooks
uv run pre-commit install

Pre-commit Hooks

This project uses pre-commit to run checks before each commit:

• ruff - Linting and auto-fixing
• ruff-format - Code formatting
• pyright - Type checking
• trailing-whitespace - Remove trailing whitespace
• end-of-file-fixer - Ensure files end with newline
• check-yaml - Validate YAML files

Run hooks manually on all files:

uv run pre-commit run --all-files

Running with MCP Inspector

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

uv run mcp 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.

Running Tests

# Run all tests (requires HEYGEN_API_KEY in .env)
uv run pytest tests/ -v

# Skip video generation tests (uses credits)
uv run pytest tests/ -v -k "not video_generation"

LLM Integration Tests

This project includes LLM-based tests using agent-benchmark to validate that AI assistants can correctly understand and use the MCP tools.

cd tests/heygen_mcp_llm_tests

# List available test scenarios
python run_llm_tests.py --list

# Run safe tests (read-only, no credits consumed)
python run_llm_tests.py

# Run a specific scenario
python run_llm_tests.py -s user-credits-test

Requirements: Azure OpenAI endpoint (AZURE_OPENAI_ENDPOINT) and HeyGen API key (HEYGEN_API_KEY).

See tests/heygen_mcp_llm_tests/README.md for full documentation.
