WHAT IT DOES

What docker_stats does on Terminal Guardian

AI agents call docker_stats 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.

RISK

Why docker_stats is rated Low

This tool queries and retrieves runtime statistics (CPU, memory, network I/O) from a running Docker container. It is a read-only operation that observes the state of the container without creating, modifying, deleting, or executing any operations.

From the tool's definition Tool name 'docker_stats' and description 'Get real-time resource usage statistics for a Docker container' indicate retrieval of monitoring data with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs docker_stats safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Terminal Guardian, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For docker_stats, this is the rule to start with:

docker_stats Allowed

docker_stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "docker_stats": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Terminal Guardian, apply this rule, and every docker_stats call is checked against it from then on.
