pr-list

THE RISK

Low Risk

Why pr-list needs a policy

This tool purely retrieves and queries pull request data without side effects. It is a read-only operation that gathers metadata about pull requests. The lack of any write, execute, or destructive operations makes this a straightforward Read category classification. Severity is low because viewing PR information poses minimal security risk even if accessed by an unauthorized AI agent.

From the tool's definition Tool description explicitly states 'Lists pull requests' with optional filters and returns structured information (PR number, state, title, author, branch, labels, draft status, merge readiness). No modification, deletion, or execution capabilities mentioned.

Documented attack patterns abuse exactly the kind of access pr-list gives an agent:

POLICY

How to control pr-list

PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for pr-list:

policy.json

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

pr-list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Make — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about pr-list

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 Make MCP Server, which means it retrieves data without modifying state.

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

Register the Make 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 Make. 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 Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Make tool call.

Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
