List Docker images.
AI agents call list_images to retrieve information from MCP Docker Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about Docker images (list operation) with no side effects, no code execution, and no data modification. It is a simple data query matching the Read category definition. Severity is low because listing images reveals only metadata about available Docker images, which is typically non-sensitive information in a Docker environment.
From the tool's definition Tool name 'list_images' and description 'List Docker images' indicate a read-only query operation that retrieves and displays Docker image data without modification.
Attacks that exploit this kind of access
List Docker images. It is categorised as a Read tool in the MCP Docker Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Docker Server MCP server in PolicyLayer and add a rule for list_images: 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 MCP Docker Server. Nothing to install.
list_images 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 list_images 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 list_images. 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.
list_images is provided by the MCP Docker Server MCP server (tenda-chi/mcp-docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
