WHAT IT DOES

What pr-list does on Npm

AI agents call pr-list to retrieve information from Npm 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-list is rated Low

This tool retrieves and queries pull request data with optional filters. It performs no creation, modification, deletion, or execution of external operations. The return of structured metadata (PR number, state, title, author, branch, labels, draft status, merge readiness) is purely informational. Misuse presents minimal risk—an agent cannot harm systems or data through listing operations alone.

From the tool's definition Tool is named 'pr-list' and description explicitly states it 'Lists pull requests' and 'Returns structured list'. The verb 'list' combined with 'returns' indicates query/retrieval with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

pr-list Allowed

pr-list 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-list": {}
  }
}

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

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