WHAT IT DOES

What pr-list does on Github

AI agents call pr-list to retrieve information from Github 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 from GitHub with optional filtering parameters. It returns structured information (PR number, state, title, author, branch, labels, draft status, merge readiness) without creating, modifying, deleting, or executing any operations. The 'list' action is a classic read-only operation with no side effects.

From the tool's definition Tool name 'pr-list' and description 'Lists pull requests with optional filters. Returns structured list...' indicates a retrieval operation with no modification or execution of external operations.

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

What does the pr-list tool do? +

Lists pull requests with optional filters. Returns structured list with PR number, state, title, author, branch, labels, draft status, and merge readiness. It is categorised as a Read tool in the Github MCP Server, which means it retrieves data without modifying state.

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

Register the Github MCP server in PolicyLayer and add a rule for pr-list: 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 Github. Nothing to install.

What risk level is pr-list? +

pr-list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit pr-list? +

Yes. Add a rate_limit block to the pr-list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pr-list completely? +

Set action: deny in the PolicyLayer policy for pr-list. 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-list? +

pr-list is provided by the Github MCP server (@paretools/github). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
