## 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 own 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."

## Use case

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.

## 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_servers": {}
  }
}
```
