What is HeyGen CLI
HeyGen CLI isHeyGenAn officially launched command-line tool and MCP server, built on the Model Context Protocol. The tool supports developers and AI assistants (such asClaude、Cursor) to directly call the HeyGen API through natural language, enabling digital human video generation, avatar and voice management, account queries, and other functions. After installation, users can directly create AI explainer videos, get video status, and manage resources in the terminal or AI conversations. HeyGen CLI is suitable for developers and automated workflow scenarios that need to generate digital human content at scale.
Main features of HeyGen CLI
- Video generation: Supports creating AI digital human explainer videos, including regular video generation, transparent background WebM format videos (convenient for post-production compositing), and converting static photos into talking videos through Avatar IV technology.
- Resource management: Can list all available AI avatars, view avatar groups (such as default groups, custom groups), get the list of avatars within a specific group, and query supported voice options.
- Account query: View the account's remaining Credits balance in real time and keep track of usage.
- Status monitoring: Supports polling video generation status to obtain download links, and can handle Webhook callback notifications to enable automatic notification after video completion.
How to use HeyGen CLI
- Environment preparation: Install Python 3.10+ and the
uvpackage manager. - Get API key: Create an API Key in the HeyGen Dashboard.
- Configure client: Add the HeyGen server in the configuration file of an MCP client such as Claude Desktop, set
uvx heygen-mcpcommand and fill in the API Key. - Start using: Directly send instructions in natural language in an AI conversation, such as "generate a product introduction video" to call it automatically.
Key information and usage requirements of HeyGen CLI
- Product positioning: An MCP (Model Context Protocol) server officially launched by HeyGen, allowing AI assistants (such as Claude, Cursor) to directly call the API through natural language.
- Core features: Supports digital human video generation, avatar and voice resource management, account Credits balance queries, video status monitoring, and Webhook callback handling.
- Technical foundation: Developed based on Python 3.10+, distributed and run using the
uvpackage manager. - Repository status: The GitHub repository is currently private, and GitHub Token authentication may be required for access or installation.
- System environment: Requires Python 3.10 or later and configuration of the
uvpackage manager.
Core advantages of HeyGen CLI
- AI-native interaction: Based on the MCP protocol, AI assistants such as Claude and Cursor can call it directly, and users can complete video generation and resource management through natural language without writing code.
- Fully automated workflow: Supports fully automatic processing of video generation, status polling, and Webhook callbacks, suitable for batch content production and unattended workflow scenarios.
- Multi-scenario video output: Can simultaneously generate standard explainer videos, transparent-background WebM videos (convenient for post-production compositing), and photo digital human videos, meeting diverse creative needs.
- One-stop resource management: Complete all resource management operations within one tool, including avatar group queries, voice list retrieval, and remaining Credits monitoring.

HeyGen CLI application scenarios
- Batch content production: E-commerce sellers and MCN agencies can use AI assistants to generate hundreds of product introduction videos in batches, automatically poll the status and download them, greatly improving labor efficiency.
- AI-assisted creation: Content creators can directly instruct in AI conversations such as Claude and Cursor to "generate a 30-second product explanation", and the AI automatically calls the tool to complete production without switching platforms.
- Marketing automation: Combined with the Webhook mechanism, video generation is automatically triggered when product data is updated, enabling automatic content updates for marketing campaigns.
- Multilingual Localization: Quickly generate different language versions of the same content by simply changing the voice parameters, suitable for the localization video needs of companies expanding overseas.
- Post-Production Integration: Through WebM transparent background video output, import digital human assets directly into Premiere, After Effects, and other software for professional-grade compositing.
