WHAT IT DOES

What docker-publish does on Docker MCP Server

AI agents invoke docker-publish to trigger actions in Docker MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why docker-publish is rated High

Publishing an image to Docker Hub is an external operation that triggers an outbound network action affecting a public registry. It is not purely a write to a local data store; it executes an external publish/push operation. Misuse could expose sensitive container images publicly, making it high severity.

From the tool's definition 'Publish the Image to the Docker Hub Registry' — pushes a local Docker image to an external public registry

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs docker-publish safely

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

docker-publish Rate-limited

docker-publish stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "docker-publish": {
      "limits": [
        {
          "counter": "docker-publish_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about docker-publish

What does the docker-publish tool do? +

Pubish the Image to the Docker Hub Registry. It is categorised as a Execute tool in the Docker MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on docker-publish? +

Register the Docker MCP Server MCP server in PolicyLayer and add a rule for docker-publish: 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 MCP Server. Nothing to install.

What risk level is docker-publish? +

docker-publish is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit docker-publish? +

Yes. Add a rate_limit block to the docker-publish 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 docker-publish completely? +

Set action: deny in the PolicyLayer policy for docker-publish. 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 docker-publish? +

docker-publish is provided by the Docker MCP Server MCP server (0xshariq/docker-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
