Heygen

Independent, unofficial connector for Heygen. Not affiliated with, endorsed by, or sponsored by Heygen. "Heygen" is a trademark of its owner, used only to identify the service this connector works with.

Agent-callable tools for HeyGen's AI video platform, over the public HeyGen v3 API (https://api.heygen.com). Generate AI avatar videos from a script or audio, generate short cinematic clips from a prompt, translate and lip-sync existing videos, drive the prompt-to-video Video Agent, synthesize speech, and browse the avatars and voices those jobs need. Video generation is asynchronous: a create tool returns an id, and you poll the matching get* tool until the job is completed and its result URLs appear.

When to use this

• Create AI videos — an avatar (or animated image) speaking a script (createVideo), a short prompt-driven cinematic clip (createCinematicVideo), or a fully agent-authored video from a text prompt (createVideoAgentVideo).
• Transform existing videos — translate into other languages (translateVideo) or replace the audio and re-sync the lips (createLipsync).
• Synthesize speech and pick voices/avatars — text-to-speech (generateSpeech), and browse/clone/design voices and browse avatar looks to resolve the ids the create tools need.
• Track async jobs and account state — poll a video/translation/lipsync/session by id, list past jobs, and check remaining credits (getCurrentUser) before generating.

Setup

This is an agentskills.io skill.

If this connector is already exposed to you as callable tools (e.g. mcp__heygen__<tool>), that's a valid path — call them directly. Everything below is only for standalone terminal use when no such tools are loaded.
