WHAT IT DOES

What network-ls does on Docker

AI agents call network-ls to retrieve information from Docker without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why network-ls is rated Low

This tool retrieves and displays information about existing Docker networks without creating, modifying, or deleting any resources. It is a non-destructive information query operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'network-ls' indicates a list operation. Description states 'Lists Docker networks with structured driver and scope information' — a read-only query with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs network-ls safely

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

network-ls Allowed

network-ls 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": {
    "network-ls": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Docker, apply this rule, and every network-ls call is checked against it from then on.

FAQ

Questions about network-ls

What does the network-ls tool do? +

Lists Docker networks with structured driver and scope information. It is categorised as a Read tool in the Docker MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on network-ls? +

Register the Docker MCP server in PolicyLayer and add a rule for network-ls: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Docker. Nothing to install.

What risk level is network-ls? +

network-ls is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit network-ls? +

Yes. Add a rate_limit block to the network-ls rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block network-ls completely? +

Set action: deny in the PolicyLayer policy for network-ls. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides network-ls? +

network-ls is provided by the Docker MCP server (@paretools/docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
