Retrieve the transcript of a video from supported platforms (YouTube, Bilibili, Vimeo, etc.). Accepts various URL formats and returns the full transcript with timestamps.
AI agents call get-transcript to retrieve information from Video Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing transcript data from video platforms without modifying, deleting, or executing any operations. It has no side effects beyond data retrieval. The blast radius of misuse is minimal—an agent could retrieve transcripts it shouldn't access, but cannot alter or destroy data, nor trigger external actions or financial impacts.
From the tool's definition Tool description explicitly states 'Retrieve the transcript' and 'returns the full transcript with timestamps'. The verb 'retrieve' and absence of any creation, modification, deletion, or execution capability indicate a read-only operation.
Attacks that exploit this kind of access
Retrieve the transcript of a video from supported platforms (YouTube, Bilibili, Vimeo, etc.). Accepts various URL formats and returns the full transcript with timestamps. It is categorised as a Read tool in the Video Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Video Toolkit MCP server in PolicyLayer and add a rule for get-transcript: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Video Toolkit. Nothing to install.
get-transcript is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get-transcript rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get-transcript. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get-transcript is provided by the Video Toolkit MCP server (jamesanz/transcript-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
