Get detailed information about a specific Docker image
AI agents call docker_image_info to retrieve information from Pacman without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves metadata about Docker images without modifying, executing, or deleting anything. It is a read-only operation that returns information to the caller, consistent with the Read category for data retrieval operations.
From the tool's definition Tool name 'docker_image_info' and description 'Get detailed information about a specific Docker image' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access docker_image_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pacman, and nothing reaches the server without passing your rules. This is the rule we recommend for docker_image_info:
{
"version": "1",
"default": "deny",
"tools": {
"docker_image_info": {}
}
}docker_image_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific Docker image. It is categorised as a Read tool in the Pacman MCP Server, which means it retrieves data without modifying state.
Register the Pacman MCP server in PolicyLayer and add a rule for docker_image_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 Pacman. Nothing to install.
docker_image_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_image_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_image_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_image_info is provided by the Pacman MCP server (oborchers/mcp-server-pacman). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pacman, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
