Get manifest of a particular image in docker hub
AI agents call docker_get_manifest to retrieve information from MCP Docker Hub Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves Docker image manifest metadata from Docker Hub, which is purely informational with no side effects. It does not create, modify, delete, or execute operations. The manifest is publicly available image metadata (layers, configuration, digest). Even if an AI agent misuses this by querying manifests it shouldn't access, the blast radius is minimal—no data is modified, deleted, or executed.
From the tool's definition Tool description states 'Get manifest of a particular image in docker hub' - a retrieval operation with no modification or destructive capability. Manifest retrieval is a read-only query of image metadata.
Attacks that exploit this kind of access
Get manifest of a particular image in docker hub. It is categorised as a Read tool in the MCP Docker Hub Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Docker Hub Server MCP server in PolicyLayer and add a rule for docker_get_manifest: 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 Hub Server. Nothing to install.
docker_get_manifest 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_get_manifest 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_get_manifest. 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_get_manifest is provided by the MCP Docker Hub Server MCP server (sirsambhav221/mcpdcoker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
