WHAT IT DOES

What create_issue does on Ncp

AI agents use create_issue 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_issue is rated Medium

This tool creates a new issue, which is a write operation that modifies state in GitHub. It is reversible (issues can be deleted or closed), so it does not qualify as Destructive. There is no financial impact, code execution, or data retrieval involved. The severity is medium because creating issues could be abused to spam a repository, but the impact is limited and contained to one repository's issue tracker.

From the tool's definition Tool description states 'Create a new issue in a GitHub repository' — this creates new data in an external system (GitHub) in a reversible manner.

RECOMMENDED RULE

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

create_issue Rate-limited

create_issue 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 Ncp, apply this rule, and every create_issue call is checked against it from then on.
