WHAT IT DOES

What list_application_envs does on Coolify

AI agents call list_application_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_application_envs is rated Low

This tool retrieves and displays environment variables without creating, modifying, deleting, or executing anything. It is a read-only information query with minimal blast radius. The only risk would be exposure of sensitive values (API keys, secrets) in the retrieved data, but that is an information disclosure concern inherent to any read operation, not a misuse vector specific to this tool.

From the tool's definition Tool name contains 'list' and description states 'List all environment variables' — a pure query operation with no modification or execution of any kind.

RECOMMENDED RULE

The rule that runs list_application_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_application_envs, this is the rule to start with:

list_application_envs Allowed

list_application_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_application_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_application_envs call is checked against it from then on.
