What update_youtube_video does on Hermoso

Why update_youtube_video is rated Medium

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

RECOMMENDED RULE

The rule that runs update_youtube_video safely

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

update_youtube_video Rate-limited

update_youtube_video 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Hermoso, apply this rule, and every update_youtube_video call is checked against it from then on.

FAQ

Questions about update_youtube_video

What does the update_youtube_video tool do? +

Edit an existing video on the connected channel: title, description, tags, and/or privacy (unlisted | public | private). THIS IS HOW YOU FLIP AN UNLISTED UPLOAD PUBLIC (post_to_youtube is public by default; unlisted only when the user asked for it). Making a video PUBLIC puts it on the channel where anyone can find it, so show the user exactly what will change and get an explicit yes before calling with privacy:. It is categorised as a Write tool in the Hermoso MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on update_youtube_video? +

Register the Hermoso MCP server in PolicyLayer and add a rule for update_youtube_video: 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 Hermoso. Nothing to install.

What risk level is update_youtube_video? +
