WHAT IT DOES

What label-create does on Docker

AI agents use label-create to create or update resources in Docker, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docker environment.

RISK

Why label-create is rated Medium

This tool creates or modifies data (a repository label) in a reversible manner. Labels can be deleted or modified, so this is a Write operation rather than Destructive. The severity is medium because creating labels in a repository could clutter or confuse the repository structure, but the impact is limited and reversible.

From the tool's definition Tool name 'label-create' indicates creation of a new repository label. Description states it 'Creates a new repository label' and returns structured data about the created label.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs label-create 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 label-create, this is the rule to start with:

label-create Rate-limited

label-create stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "label-create": {
      "limits": [
        {
          "counter": "label-create_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about label-create

What does the label-create tool do? +

Creates a new repository label. Returns structured data with label name, description, color, and URL. It is categorised as a Write tool in the Docker MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on label-create? +

Register the Docker MCP server in PolicyLayer and add a rule for label-create: 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 label-create? +

label-create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit label-create? +

Yes. Add a rate_limit block to the label-create 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 label-create completely? +

Set action: deny in the PolicyLayer policy for label-create. 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 label-create? +

label-create 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.
