List Docker containers with detailed information.
AI agents call list_containers to retrieve information from MCP Docker Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about existing Docker containers without modifying, executing, or deleting anything. It is a passive read operation with minimal risk even if misused by an AI agent, as it only returns metadata about container state.
From the tool's definition Tool name 'list_containers' and description 'List Docker containers with detailed information' indicates a query/retrieval operation with no modification or execution capability.
Attacks that exploit this kind of access
List Docker containers with detailed information. It is categorised as a Read tool in the MCP Docker Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Docker Server 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 MCP Docker Server. 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 MCP Docker Server MCP server (tenda-chi/mcp-docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
