Get Docker version information
AI agents call docker_system_version to retrieve information from Docker MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves Docker system version information, which is a read-only query with no side effects. It does not create, modify, delete, or execute arbitrary commands—it simply fetches and returns metadata about the Docker installation.
From the tool's definition Tool name 'docker_system_version' and description 'Get Docker version information' indicate a query operation that retrieves version metadata without modifying state or executing arbitrary operations.
Attacks that exploit this kind of access
Get Docker version information. It is categorised as a Read tool in the Docker MCP MCP Server, which means it retrieves data without modifying state.
Register the Docker MCP server in PolicyLayer and add a rule for docker_system_version: 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. Nothing to install.
docker_system_version 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_system_version 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_system_version. 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_system_version is provided by the Docker MCP server (sondt2709/docker-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
