WHAT IT DOES

What pr-update does on Test

AI agents use pr-update 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-update is rated Medium

This tool modifies PR attributes reversibly (title, body, labels, assignees, etc.) but does not delete data or execute code. The changes can be undone by subsequent updates. While it affects development workflow and collaboration, the scope is limited to PR metadata manipulation rather than code execution, resource destruction, or financial operations.

From the tool's definition Tool description explicitly states it 'Updates pull request metadata (title, body, labels, assignees, reviewers, milestone, base branch, projects)'. The verb 'Updates' combined with listed modification targets indicates data modification capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-update 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-update, this is the rule to start with:

pr-update Rate-limited

pr-update 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "pr-update": {
      "limits": [
        {
          "counter": "pr-update_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Test, apply this rule, and every pr-update call is checked against it from then on.

It is categorised as a Write tool in the Test MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on pr-update? +

Register the Test MCP server in PolicyLayer and add a rule for pr-update: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Test. Nothing to install.

What risk level is pr-update? +

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

Can I rate-limit pr-update? +

How do I block pr-update completely? +

Set action: deny in the PolicyLayer policy for pr-update. 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.

What MCP server provides pr-update? +

pr-update is provided by the Test MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
