Why issue-close needs a policy

Closing an issue is a reversible state change (issues can be reopened), making it a Write operation. It modifies the state of an existing issue and optionally adds a comment. Misuse could disrupt workflows by closing issues prematurely, but the action is not irreversible.

From the tool's definition Closes an issue with an optional comment and reason

Documented attack patterns abuse exactly the kind of access issue-close gives an agent:

POLICY

How to control issue-close

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 issue-close:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "issue-close": {
      "limits": [
        {
          "counter": "issue-close_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

issue-close 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.

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 issue-close

What does the issue-close tool do? +

Closes an issue with an optional comment and reason. Returns structured data with issue number, state, URL, reason, and comment URL. It is categorised as a Write tool in the Make MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on issue-close? +

Register the Make MCP server in PolicyLayer and add a rule for issue-close: 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 issue-close? +

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

Can I rate-limit issue-close? +

Yes. Add a rate_limit block to the issue-close 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 issue-close completely? +

Set action: deny in the PolicyLayer policy for issue-close. 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 issue-close? +

issue-close 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.
