Frequently asked questions
Can I see all available AI avatars via AI?
Yes! Use the list_avatars tool. Your agent will retrieve the complete directory of stock avatars available in Synthesia for your videos.
How do I check the status of a video being processed?
Run the get_video_details query with your Video ID. The agent will retrieve the real-time status (e.g., in_progress, completed) and the final download link if ready.
Is it possible to generate a video using a custom template?
Absolutely. Use the create_video_from_template tool. Provide the Template ID and a JSON object with the data for your dynamic variables to trigger the generation.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Synthesia tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
