WHAT IT DOES

What issue-close does on Npm

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

RISK

Why issue-close is rated Medium

This tool performs an irreversible state change (closing an issue), which is a modification action. While the effect could theoretically be undone by reopening the issue, the primary action is to write/modify issue state. The severity is medium because misuse could disrupt project workflows (spam closing legitimate issues), but the scope is limited to individual issues and the action is reversible.

From the tool's definition Tool explicitly 'Closes an issue with an optional comment' — this modifies state (issue state changes from open to closed) and is reversible (issues can be reopened), and can add comments.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs issue-close safely

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

issue-close Rate-limited

issue-close 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 Npm, apply this rule, and every issue-close call is checked against it from then on.
