WHAT IT DOES

What pr-view does on Git

AI agents call pr-view to retrieve information from Git without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pr-view is rated Low

This tool retrieves and returns information about pull requests in a read-only manner. It performs no mutations, does not execute code, does not delete data, and does not involve financial transactions. The data returned (state, checks, review decision, diff stats, author, labels, etc.) are all informational outputs from querying an existing pull request.

From the tool's definition Tool name 'pr-view' and description states it 'Views a pull request' and 'Returns structured data' — retrieval and querying operations with no modification or execution capabilities.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs pr-view safely

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

pr-view Allowed

pr-view is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "pr-view": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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