WHAT IT DOES

What docker_check_availability does on Code MCP Server

AI agents call docker_check_availability to retrieve information from Code 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_check_availability is rated Low

This tool performs a non-destructive query of the system environment to determine if Docker is present. It retrieves information about system configuration without side effects, making it a Read operation. The severity is low because even if misused, it only returns availability status without affecting any system state, data, or operations.

From the tool's definition Tool name 'docker_check_availability' and description 'Check if Docker is installed and available' indicate a status check operation that queries system state without modifying or executing anything.

RECOMMENDED RULE

The rule that runs docker_check_availability safely

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

docker_check_availability Allowed

docker_check_availability 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_check_availability": {}
  }
}

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

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

How do I block docker_check_availability completely? +

Set action: deny in the PolicyLayer policy for docker_check_availability. 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.
