What images does on Test
AI agents call images to retrieve information from Test without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why images is rated Low
This tool performs a read-only operation that queries Docker image metadata and returns structured information. There are no side effects, no code execution, no data modification, and no destructive actions. The blast radius of misuse is minimal—an agent could only gain visibility into available Docker images, which is informational only.
From the tool's definition Tool name 'images' and description 'Lists Docker images with structured repository, tag, size, and creation info' indicate a query operation that retrieves and returns data about Docker images without modifying or executing anything.
Attacks that exploit this kind of access
The rule that runs images safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Test, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For images, this is the rule to start with:
images is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Test, apply this rule, and every images call is checked against it from then on.
Questions about images
Lists Docker images with structured repository, tag, size, and creation info. It is categorised as a Read tool in the Test MCP Server, which means it retrieves data without modifying state.
Register the Test MCP server in PolicyLayer and add a rule for 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 Test. Nothing to install.
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 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 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.
images is provided by the Test MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
