WHAT IT DOES

What create_clip does on Ncp

AI agents use create_clip 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 create_clip is rated Medium

This tool creates a new clip on Twitch, which is a reversible write operation (clips can be deleted). It has moderate blast radius as it could be used to create unwanted clips from a stream, but does not irreversibly destroy data or involve financial transactions.

From the tool's definition 'Create Twitch clip' — creates a new clip resource on Twitch

RECOMMENDED RULE

The rule that runs create_clip 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 create_clip, this is the rule to start with:

create_clip Rate-limited

create_clip 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.
