WHAT IT DOES

What docker-restart does on Docker MCP Server

AI agents invoke docker-restart 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-restart is rated High

This tool executes container lifecycle operations with side effects that cannot be rolled back once the restart completes. While not destructive (data persists if properly configured) or financial, it directly triggers external system state changes. The blast radius is high: restarting a production database container could cause downtime, restart loops, or loss of in-memory state.

From the tool's definition "Restart Docker containers" - this triggers external operations (container restart) whose effects depend on arguments (which containers, timeout settings).

Attacks that exploit this kind of access

RECOMMENDED RULE

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

docker-restart Rate-limited

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

FAQ

Questions about docker-restart

What does the docker-restart tool do? +

Restart Docker containers with optional timeout. 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-restart? +

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

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

Can I rate-limit docker-restart? +

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

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

docker-restart 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.
