Why youtube_transcript is rated Medium

An AI agent can call youtube_transcript faster than any human can review: one bad instruction and it creates or modifies resources in Crawlora by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs youtube_transcript safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crawlora, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For youtube_transcript, this is the rule to start with:

youtube_transcript Rate-limited

youtube_transcript stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
