WHAT IT DOES

What pr-close does on Test

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

RISK

Why pr-close is rated Medium

Closing a PR is a write operation that modifies state reversibly. While branch deletion could be considered destructive if permanent, the tool's primary function is state modification rather than irreversible destruction—most Git platforms allow PR reopening and branches can be recovered.

From the tool's definition Tool description states it 'Closes a pull request' and includes 'optional branch deletion'. These are reversible modifications to repository state (PR can be reopened, branch can be restored from reflog).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-close safely

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

pr-close Rate-limited

pr-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.
