WHAT IT DOES

What pr-review does on Docker

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

RISK

Why pr-review is rated Medium

The tool creates a PR review submission (approve, request changes, or comment), which is a reversible write operation on a code repository. It does not delete data or execute code, but it can influence merge decisions, giving it medium severity if misused by an AI agent.

From the tool's definition Submits a review on a pull request (approve, request-changes, or comment)

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-review safely

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

pr-review Rate-limited

pr-review 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 Docker, apply this rule, and every pr-review call is checked against it from then on.

What risk level is pr-review? +

pr-review is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pr-review? +

How do I block pr-review completely? +

Set action: deny in the PolicyLayer policy for pr-review. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
