AI agents call docker_get_container_stats to retrieve information from Homelab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical information (CPU and memory usage) about running containers. It has no side effects, does not modify infrastructure state, does not execute arbitrary code, and does not create financial obligations. It falls squarely into the Read category as a passive data query operation.
From the tool's definition Tool description states 'Get CPU and memory stats for containers on a host' — a read-only retrieval operation that queries monitoring data without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
Get CPU and memory stats for containers on a host. It is categorised as a Read tool in the Homelab MCP Server, which means it retrieves data without modifying state.
Register the Homelab MCP server in PolicyLayer and add a rule for docker_get_container_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 Homelab. Nothing to install.
docker_get_container_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_get_container_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_get_container_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_get_container_stats is provided by the Homelab MCP server (myraffy/homelab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
