WHAT IT DOES

What youtube_add_comment does on ScopeGate

AI agents use youtube_add_comment to create or update resources in ScopeGate, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScopeGate environment.

RISK

Why youtube_add_comment is rated Medium

This tool creates new data (a comment) on YouTube, which is reversible (comments can be deleted by the user or removed by moderation). It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition Tool name is 'youtube_add_comment' and description states 'Add a comment to a YouTube video'. The 'add' verb and action of creating new content (a comment) on a third-party platform classifies this as a Write operation.

RECOMMENDED RULE

The rule that runs youtube_add_comment safely

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

youtube_add_comment Rate-limited

youtube_add_comment 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.
