List Docker containers running on the current daemon.
AI agents call list_containers to retrieve information from Universal Mcp Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation that retrieves the state of Docker containers. It has no side effects, does not modify system state, does not execute arbitrary commands, and does not delete or manage container lifecycles. It is purely informational and therefore falls into the Read category.
From the tool's definition list_containers: List Docker containers running on the current daemon. The tool retrieves information about running containers without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
List Docker containers running on the current daemon. It is categorised as a Read tool in the Universal Mcp Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Universal Mcp Toolkit 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 Universal Mcp Toolkit. 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 Universal Mcp Toolkit MCP server (markgatcha/universal-mcp-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
