WHAT IT DOES

What list_servers does on Coolify

AI agents call list_servers to retrieve information from Coolify without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_servers is rated Low

This tool retrieves and displays information about servers without creating, modifying, deleting, or executing any operations. It is a standard query operation with no side effects, fitting the Read category. Severity is low because listing servers provides inventory information but does not directly expose sensitive capabilities or enable destructive actions without further tool usage.

From the tool's definition Tool name is 'list_servers' and description states 'List all servers registered in Coolify.' The verb 'list' and action of retrieving/querying server information with no modification indicates a read-only operation.

RECOMMENDED RULE

The rule that runs list_servers safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Coolify, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_servers, this is the rule to start with:

list_servers Allowed

list_servers 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": {
    "list_servers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Coolify, apply this rule, and every list_servers call is checked against it from then on.
