WHAT IT DOES

What list_service_envs does on Coolify

AI agents call list_service_envs 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_service_envs is rated Low

This tool retrieves environment variable information for a service without creating, modifying, deleting, or executing any actions. It is a pure read operation with minimal blast radius—the worst outcome is exposure of sensitive environment variable names or non-secret metadata, but the tool itself performs no destructive or side-effect operations.

From the tool's definition Tool name 'list_service_envs' and description 'List environment variables for a service' indicate a query/retrieval operation with no modification of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_service_envs 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_service_envs, this is the rule to start with:

list_service_envs Allowed

list_service_envs 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_service_envs": {}
  }
}

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_service_envs call is checked against it from then on.
