## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_application_envs",
    "arguments": {}
  }
}
```

## 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 own definition: "Tool name contains 'list' and description states 'List all environment variables' — a pure query operation with no modification or execution of any kind."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Coolify:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_application_envs": {}
  }
}
```
