List Docker containers
AI agents call docker_list_containers to retrieve information from Cargoshipper 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 Docker containers without modifying, deleting, or executing anything. It is a read-only operation equivalent to running 'docker ps'. While the cargoshipper-mcp server as a whole has access to infrastructure management APIs (some of which are destructive, like cf_delete_zone and cf_delete_dns_record), this specific tool performs only data retrieval.
From the tool's definition Tool name is 'docker_list_containers' and description states 'List Docker containers' — a query operation with no side effects.
Attacks that exploit this kind of access
List Docker containers. It is categorised as a Read tool in the Cargoshipper MCP Server, which means it retrieves data without modifying state.
Register the Cargoshipper MCP server in PolicyLayer and add a rule for docker_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 Cargoshipper. Nothing to install.
docker_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 docker_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 docker_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.
docker_list_containers is provided by the Cargoshipper MCP server (scarr7981/cargoshipper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
