WHAT IT DOES

What docker-logout does on Docker MCP Server

AI agents invoke docker-logout 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-logout is rated High

Logging out from a Docker registry triggers an external authentication operation (removes stored credentials/session for a registry). It is not purely read-only, but it is also not directly destructive to data. It executes an external operation (credential revocation/removal) that affects the system's ability to interact with registries.

RECOMMENDED RULE

The rule that runs docker-logout 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-logout, this is the rule to start with:

docker-logout Rate-limited

docker-logout 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-logout": {
      "limits": [
        {
          "counter": "docker-logout_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-logout call is checked against it from then on.

FAQ

Questions about docker-logout

What does the docker-logout tool do? +

Log out from a Docker 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-logout? +

Register the Docker MCP Server MCP server in PolicyLayer and add a rule for docker-logout: 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-logout? +

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

Can I rate-limit docker-logout? +

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

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

docker-logout 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.
