THE RISK

Low Risk

Why list-resources needs a policy

This tool retrieves and enumerates existing Coolify resources without creating, modifying, deleting, or executing any operations. The blast radius is minimal—an AI agent misusing this tool could only gain visibility into what resources exist in the Coolify environment, not alter or control them.

From the tool's definition Tool name 'list-resources' and description 'Retrieve a comprehensive list of all resources' indicates a query operation with no side effects.

POLICY

How to control list-resources

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-resources:

policy.json

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

list-resources 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.

Questions about list-resources

What does the list-resources tool do? +

Retrieve a comprehensive list of all resources managed by Coolify. This includes applications, services, databases, and deployments. It is categorised as a Read tool in the Coolify MCP Server MCP Server, which means it retrieves data without modifying state.

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

Register the Coolify MCP Server MCP server in PolicyLayer and add a rule for list-resources: 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-resources? +

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

Can I rate-limit list-resources? +

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

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

list-resources is provided by the Coolify MCP Server MCP server (stumason/coolify-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

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.
