WHAT IT DOES

What upload_video does on Ncp

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

RISK

Why upload_video is rated Medium

This tool creates new data (uploads a video) on an external platform. While the upload itself is a write operation that modifies YouTube's state, it is reversible (the video can be deleted or made private). It does not move money (not Financial), does not execute arbitrary code (not Execute), and does not irreversibly destroy data (not Destructive).

From the tool's definition Tool name: 'upload_video'. Description: 'Upload video to YouTube'. The tool creates/adds new media content to a platform (YouTube), which is a reversible write operation.

RECOMMENDED RULE

The rule that runs upload_video safely

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

upload_video Rate-limited

upload_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.
