HeyGen and Lovable Integration Brings Prompt Based Video to AI App Building

May 28, 2026

HeyGen, an AI video generation platform specializing in digital twins, launched a hosted Model Context Protocol (MCP) endpoint (a standard for connecting AI models to external tools) that integrates with the Lovable app builder. This "Remote MCP" uses OAuth for authentication, allowing AI agents to access a user's existing HeyGen account.

Protocol: Model Context Protocol (Remote)
Authentication: OAuth
Supported plans: All HeyGen plans
Core capabilities: Video generation, translation, lipsync, and more

The integration expands on HeyGen's agentic CLI and the Granola video generation skill to further standardize video as a programmable asset. This standardization lowers the barrier for adding high-fidelity avatars to functional web applications without writing custom REST wrappers or managing complex production auth flows.

You can now use natural language to prompt talking-head videos and translations directly within Lovable. The service is available on all HeyGen plans and supports tools like create_video_agent for one-shot rendering. To connect a custom agent, point it to the hosted endpoint at https://mcp.heygen.com/mcp/v1/.

You can build an app in an afternoon. Until now, adding video still meant APIs, auth, and production work. HeyGen is now integrated with @Lovable via MCP + OAuth. Prompt avatar video directly into your app and ship with a face and voice. What would you build first? https://t.co/xCMXXtghHH

Still wondering? A few quick answers below.

HeyGen Remote MCP is a hosted implementation of the Model Context Protocol that allows AI agents to create videos using your HeyGen account. Unlike local servers, this remote version runs on HeyGen infrastructure and uses OAuth for authentication, meaning you do not need to manage API keys or run any code locally to connect your agents.

The integration allows the Lovable app builder to connect to HeyGen tools through a hosted endpoint. Once authenticated via OAuth, you can use natural language prompts within Lovable to generate avatar videos, add voiceovers, or perform lip-syncing. This allows you to build and ship functional applications with integrated AI video features in a single afternoon.

Remote MCP is available to users on all HeyGen plans. The video generation performed by your AI agents uses the existing credits included in your current subscription plan, so there are no separate API charges or additional billing requirements to use these agentic features through the Model Context Protocol endpoint.

AI agents gain access to a comprehensive suite of tools including one-shot video generation, video translation with voice cloning, and lip-syncing for existing videos. Agents can also manage avatars by listing groups, creating photo avatars, or generating new digital twins from video footage, all through standardized function calls provided by the protocol.

While the standard HeyGen API provides direct endpoints for programmatic control and requires manual integration code, Remote MCP wraps these capabilities into a standardized format that AI agents can understand. This allows agents to use HeyGen tools conversationally and autonomously without the developer needing to write custom integration logic for every feature.
