List Docker containers with status, ports, CPU/memory usage, and uptime.
AI agents call docker_containers to retrieve information from RedisNexus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries container metadata only. It performs passive observation of container state without triggering deployments, executing commands within containers, or modifying infrastructure. The action verb is 'list,' which is a classic Read operation. No side effects or blast radius if misused by an AI agent.
From the tool's definition Tool description states it 'List[s] Docker containers with status, ports, CPU/memory usage, and uptime' — purely informational retrieval with no modification, deletion, or command execution.
Attacks that exploit this kind of access
List Docker containers with status, ports, CPU/memory usage, and uptime. It is categorised as a Read tool in the RedisNexus MCP Server, which means it retrieves data without modifying state.
Register the RedisNexus MCP server in PolicyLayer and add a rule for docker_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 RedisNexus. Nothing to install.
docker_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_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_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_containers is provided by the RedisNexus MCP server (rajkumar-madhu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
docker_containers is one line of RedisNexus's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
