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

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

## Why docker_ps is rated Low

This tool performs passive information retrieval about running Docker containers. It is analogous to the standard 'docker ps' command, which lists containers but does not execute code, modify containers, or cause destructive actions. The blast radius of misuse is minimal—an attacker could gain visibility into the container environment but cannot directly compromise it through this tool alone.

From the tool's own definition: "Tool name 'docker_ps' and description 'List Docker containers with their status, image, and port information' indicate a read-only query operation that retrieves container metadata without modifying, executing, or deleting anything."

## Use case

AI agents call docker_ps to retrieve information from Terminal Guardian 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 Terminal Guardian:

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