What is HeyGen CLI?

HeyGen CLI is the official command-line tool and MCP server released by HeyGen, built on the Model Context Protocol. The tool allows developers and AI assistants (such as Claude and Cursor) to directly call the HeyGen API via natural language, enabling functions such as digital human video generation, avatar and voice management, and account querying. After installation, users can directly create AI-generated explanation videos, obtain video status, and manage resources in the terminal or AI dialogue. HeyGen CLI is suitable for developers who need to generate digital human content in batches and for automated workflow scenarios.

Main functions of HeyGen CLI

  • Video generationSupports the creation of AI digital human narration videos, including regular video generation, transparent background WebM format videos (for easy post-production compositing), and converting still photos into talking videos using Avatar IV technology.
  • Resource ManagementIt can list all available AI avatars, view avatar groups (such as default group and custom group), get a list of avatars within a specific group, and query supported voice options.
  • Account InquiryView your account's remaining Credits balance in real time and keep track of its usage.
  • Status monitoringIt supports polling the video generation status to obtain the download link, and can handle Webhook callback notifications to achieve automatic notifications when the video is completed.

How to use HeyGen CLI

  • Environmental preparationInstall Python 3.10+ and uv Package manager.
  • Get KeyCreate an API Key in the HeyGen Dashboard.
  • Configure the clientAdd the HeyGen server to the configuration file of MCP clients such as Claude Desktop and configure it. uvx heygen-mcp Enter the API Key in the command field.
  • Start usingYou can send commands directly in natural language during AI dialogue, such as "generate a product introduction video," which can be automatically invoked.

HeyGen CLI's core advantages

  • AI native interactionBased on the MCP protocol, AI assistants such as Claude and Cursor can be directly invoked, allowing users to generate videos and manage resources using natural language without writing code.
  • Full process automationIt supports fully automated processing of video generation, status polling, and Webhook callbacks, making it suitable for batch content production and unattended workflow scenarios.
  • Multi-scene video outputIt can simultaneously generate standard instructional videos, transparent background WebM videos (for easy post-production compositing), and photo-digital human videos to meet diverse creative needs.
  • One-stop resource managementComplete all resource management operations, such as avatar grouping query, voice list retrieval, and remaining credits monitoring, within a single tool.

Application Scenarios of HeyGen CLI

  • Mass content productionE-commerce sellers and MCN agencies can use the AI assistant to generate hundreds of product introduction videos in batches, automatically poll for status and download them, greatly improving efficiency.
  • AI-assisted creationContent creators can directly instruct AI such as Claude and Cursor to "generate a 30-second product description," and the AI will automatically call the tools to complete the production without switching platforms.
  • Marketing AutomationBy combining the Webhook mechanism, video generation is automatically triggered when product data is updated, enabling automatic updates of marketing campaign content.
  • Multilingual localizationQuickly generate different language versions of the same content by simply changing the voice parameters, suitable for the localization video needs of companies going global.
  • Post-production integrationBy using WebM transparent background video output, digital human footage can be directly imported into software such as Premiere and After Effects for professional-grade compositing.
