run can trigger actions in Docker, with no limits today. PolicyLayer puts allow, deny, and rate-limit rules on every call. Live in minutes.

AI agents invoke run to trigger processes or run actions in Docker. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

run can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access run gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so run only ever does what you allow.

Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.

What does the run tool do? +

Runs a Docker container from an image and returns structured container ID and status.. It is categorised as a Execute tool in the Docker MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run? +

Register the Docker MCP server in PolicyLayer and add a rule for run: 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. Nothing to install.

What risk level is run? +

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

Can I rate-limit run? +

Yes. Add a rate_limit block to the run 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 run completely? +

Set action: deny in the PolicyLayer policy for run. 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 run? +

run is provided by the Docker MCP server (@paretools/docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Docker tool call.
