Get Docker version information
AI agents call system_version to retrieve information from Docker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves Docker version information, which is a read-only operation with no side effects. It does not create, modify, delete, or execute any operations on containers, images, networks, or volumes. The blast radius of misuse is minimal—an attacker could only learn version information, which may inform further attacks but causes no direct damage. This is classified as Read/low severity.
From the tool's definition Tool name 'system_version' and description 'Get Docker version information' indicate a query operation that retrieves system metadata without modifying any Docker resources.

Attacks that exploit this kind of access
Get Docker version information. It is categorised as a Read tool in the Docker MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Docker MCP Server MCP server in PolicyLayer and add a rule for 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 Server. Nothing to install.
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 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 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.
system_version is provided by the Docker MCP Server MCP server (swartdraak/docker-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
system_version is one line of Docker MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
