Sync MCP Server

An open-source Model Context Protocol (MCP) server for the Sync API. Gives AI agents the ability to create lipsync videos, manage assets, check generation status, and more.

Tools are auto-generated from the Sync OpenAPI spec at startup. As new API endpoints ship, they become available to agents automatically — no server update needed.
