Get Docker system information
AI agents call system_info 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 read-only system-level information about the Docker daemon and environment. It has no side effects and cannot modify, execute, or delete any Docker resources. The lack of action verbs like 'create', 'modify', 'delete', or 'execute' combined with the 'Get' verb in the description clearly indicates a Read operation with minimal blast radius.
From the tool's definition Tool name is 'system_info' with description 'Get Docker system information' - describes a retrieval operation with no modification of Docker objects, containers, images, networks, or volumes.

Get Docker system 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_info: 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_info 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_info 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_info. 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_info 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.
