HeyGen guide: wiring Meta's Muse Agent to MCP for automated avatar videos

HeyGen · x · 2026-09-24

HeyGen published a guide to connecting Meta's Muse Agent with the HeyGen MCP. Muse runs as a Mac/iOS app and at muse.ai, backed by an isolated cloud Linux box with its own browser, so it keeps working after your laptop shuts.

Muse acts as a scheduled worker, not a chat window: one standing instruction makes it search daily, pick a story, and write the script in your voice; your single 'yes' fires the HeyGen MCP and puts your avatar on camera. The guide covers setup and workspace connection steps.
