WHEN AI AGENTS USE THIS TOOL

AI agents call stop_container to perform operations in Docker. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.

WHY ENFORCE A POLICY ON STOP_CONTAINER

Applying a policy to stop_container gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.

RECOMMENDED POLICY

Apply a rate limit to control usage and monitor for unexpected behaviour.

docker.yaml 
tools:
  stop_container:
    rules:
      - action: allow
        rate_limit:
          max: 60
          window: 60

FREQUENTLY ASKED QUESTIONS

What does the stop_container tool do?

Halt a running container. It is categorised as a Other tool in the Docker MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on stop_container?

Add a rule in your Intercept YAML policy under the tools section for stop_container. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Docker MCP server.

What risk level is stop_container?

stop_container is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit stop_container?

Yes. Add a rate_limit block to the stop_container rule in your Intercept 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 stop_container completely?

Set action: deny in the Intercept policy for stop_container. 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 stop_container?

stop_container is provided by the Docker MCP server (ckreiling/mcp-server-docker). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
