Get Docker system information
AI agents call docker_system_info 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 metadata (version, storage driver, running containers count, etc.) without modifying state, executing commands, or triggering container actions. It is purely informational and read-only, making it a Read category risk with low severity.
From the tool's definition Tool name 'docker_system_info' and description 'Get Docker system information' indicate a query/retrieval operation. The verb 'get' combined with 'system information' suggests passive data retrieval with no modification or execution of containers.
Attacks that exploit this kind of access
Get Docker system 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_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. Nothing to install.
docker_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 docker_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 docker_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.
docker_system_info 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.
