docker-stop · Docker MCP Server MCP: Risk & Policy

WHAT IT DOES

What docker-stop does on Docker MCP Server

AI agents invoke docker-stop 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.

WHY IT NEEDS A POLICY

Why docker-stop needs a policy

While stopping a container is technically reversible (containers can be restarted), the tool executes external Docker operations whose effects depend on which container(s) are targeted.

From the tool's definition Tool name 'docker-stop' with description 'Stop Docker containers' indicates execution of container lifecycle operations. This performs irreversible state transitions of running containers, affecting system resources and application availability.

Verdict

docker-stop Rate-limited

docker-stop 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Docker MCP Server, so you can run agents against it safely.

FAQ

Questions about docker-stop

What does the docker-stop tool do? +

Stop Docker containers. 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-stop? +

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

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

Can I rate-limit docker-stop? +

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

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

docker-stop 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.
