What docker_stats does on Mcp Control Plane
AI agents call docker_stats to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why docker_stats is rated Low
docker_stats retrieves and queries runtime metrics from Docker containers without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk even if misused by an agent—it only exposes monitoring data that is typically already visible to container administrators.
From the tool's definition Tool returns Docker container statistics (CPU, memory, network, block IO) with no modification capability implied by 'one-shot' retrieval pattern and read-only nature of stats collection.
Attacks that exploit this kind of access
The rule that runs docker_stats safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For docker_stats, this is the rule to start with:
docker_stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every docker_stats call is checked against it from then on.
Questions about docker_stats
Return one-shot Docker container CPU, memory, network, and block IO stats. It is categorised as a Read tool in the Mcp Control Plane MCP Server, which means it retrieves data without modifying state.
Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for docker_stats: 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 Mcp Control Plane. Nothing to install.
docker_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the docker_stats 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.
Set action: deny in the PolicyLayer policy for docker_stats. 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.
docker_stats is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
