docker_container_restart · Infra Ops MCP: Risk & Policy

WHAT IT DOES

What docker_container_restart does on Infra Ops

AI agents invoke docker_container_restart to trigger actions in Infra Ops. 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_container_restart needs a policy

Restarting a Docker container is an Execute action—it runs a command that causes an external system (the container runtime) to perform an operation whose effects depend on the container identifier provided as an argument. While not destructive (data persists), restarting containers can interrupt services, cause downtime, or trigger cascading failures in dependent systems.

From the tool's definition Tool name 'docker_container_restart' and description 'Restart a Docker container' indicate execution of a container management operation that triggers external service state changes.

Verdict

docker_container_restart Rate-limited

docker_container_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.

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

FAQ

Questions about docker_container_restart

What does the docker_container_restart tool do? +

Restart a Docker container. It is categorised as a Execute tool in the Infra Ops 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_container_restart? +

Register the Infra Ops MCP server in PolicyLayer and add a rule for docker_container_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 Infra Ops. Nothing to install.

What risk level is docker_container_restart? +

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

Can I rate-limit docker_container_restart? +

Yes. Add a rate_limit block to the docker_container_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_container_restart completely? +

Set action: deny in the PolicyLayer policy for docker_container_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_container_restart? +

docker_container_restart is provided by the Infra Ops MCP server (skyvanguard/infra-ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
