Frequently asked questions
Can I trigger auto-transcription for a video using the agent?
Yes! Use the transcribe_video tool with the Project ID. Your agent will trigger CaptionHub's AI engine to start transcribing the video content instantly.
How do I get the download link for finished subtitles?
Simply ask the agent to export_captions and provide the Project ID and the language code (e.g., 'fr' or 'es'). It will return the export URL for your finished caption set.
Does the integration allow approving captions via the workspace?
Yes. Use the approve_captions tool with the Project ID and Language. This will mark the specific caption set as approved in your CaptionHub workflow.
How does Google ADK connect to MCP servers?
Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.
Can ADK agents use multiple MCP servers?
Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.
Which Gemini models work best with MCP tools?
Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
