WHAT IT DOES

What docker-containers does on Docker MCP Server

AI agents call docker-containers to retrieve information from Docker MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why docker-containers is rated Low

This tool queries Docker container information with no side effects. Listing containers is a non-destructive, informational operation. While it could expose information about running services, the severity is low because it performs no actions, creates no data, and cannot be misused to cause damage. Confidence is high due to explicit 'List' language in the description.

From the tool's definition Tool name 'docker-containers' and description 'List Docker containers on the host system' indicate a read-only operation that retrieves container state without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs docker-containers safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Docker MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For docker-containers, this is the rule to start with:

docker-containers Allowed

docker-containers is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "docker-containers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Docker MCP Server, apply this rule, and every docker-containers call is checked against it from then on.

FAQ

Questions about docker-containers

What does the docker-containers tool do? +

List Docker containers on the host system. It is categorised as a Read tool in the Docker MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on docker-containers? +

Register the Docker MCP Server 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 Docker MCP Server. Nothing to install.

What risk level is docker-containers? +

docker-containers is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit docker-containers? +

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.

How do I block docker-containers completely? +

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.

What MCP server provides docker-containers? +

docker-containers is provided by the Docker MCP Server MCP server (0xshariq/docker-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
