About Synthesia MCP Server
Connect your Synthesia AI video account to any AI agent and simplify how you create professional avatar-led videos, manage video templates, and monitor production status through natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with Synthesia through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- AI Video Generation — Create high-quality videos by providing a script and selecting an avatar programmatically via AI.
- Template Automation — Generate videos by filling dynamic variables in pre-defined Synthesia Studio templates.
- Avatar Directory — List available stock avatars and retrieve detailed metadata to choose the right persona for your content.
- Production Monitoring — Check real-time processing status and retrieve final video links directly from the agent.
- History Oversight — List and query all previously generated videos and manage your production library.
- Workflow Webhooks — Manage notification endpoints to receive real-time updates when your videos are finished.
The Synthesia MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
