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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
