获取容器列表（包括停止的容器）
AI agents call list_containers to retrieve information from ContainerGuard MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists container information without creating, modifying, executing commands, or deleting any resources. It is a read-only operation that gathers container metadata. The low severity reflects minimal blast radius if misused—disclosure of container inventory poses limited direct risk compared to execution or destructive tools.
From the tool's definition Tool name 'list_containers' and description 'get container list (including stopped containers)' indicate a query/retrieval operation with no modification or execution of side effects.
Attacks that exploit this kind of access
获取容器列表（包括停止的容器）. It is categorised as a Read tool in the ContainerGuard MCP MCP Server, which means it retrieves data without modifying state.
Register the ContainerGuard MCP server in PolicyLayer and add a rule for list_containers: 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 ContainerGuard MCP. Nothing to install.
list_containers 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 list_containers 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 list_containers. 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.
list_containers is provided by the ContainerGuard MCP server (rockmelodies/containerguardmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
