THE RISK

Low Risk

Why list-services needs a policy

This tool performs a read-only retrieval of service information. It does not create, modify, delete, or execute operations. The blast radius is minimal as it only exposes metadata about existing services. No authentication bypass or privilege escalation is implied by merely listing services.

From the tool's definition Tool name 'list-services' and description 'Retrieve a list of all services managed by Coolify' indicate a query operation that retrieves data without side effects.

POLICY

How to control list-services

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

policy.json

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

list-services 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 Coolify MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

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

Register the Coolify MCP Server MCP server in PolicyLayer and add a rule for list-services: 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 Coolify MCP Server. Nothing to install.

What risk level is list-services? +

Can I rate-limit list-services? +

Yes. Add a rate_limit block to the list-services 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 list-services completely? +

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

Enforce policy on every Coolify MCP Server tool call.

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