Lista todos los contenedores Docker activos
AI agents call list_containers to retrieve information from Docker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves information about existing Docker containers without creating, modifying, deleting, or executing any operations. It is purely informational, making it a Read category tool with low severity since listing containers poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'list_containers' and description 'Lista todos los contenedores Docker activos' (Lists all active Docker containers) indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Lista todos los contenedores Docker activos. It is categorised as a Read tool in the Docker MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Docker MCP 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 Docker MCP 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 Docker MCP Server MCP server (rodrigouc/docker-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
