What lookup_dockerhub does on GoCreative Agent API
AI agents call lookup_dockerhub to retrieve information from GoCreative Agent API without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
Why lookup_dockerhub is rated Low
This tool performs a straightforward data retrieval operation against Docker Hub's public API. It gathers metadata about published container images for analysis purposes. While Docker Hub queries could theoretically be used for reconnaissance (identifying vulnerable images to target), the tool itself has no capacity to execute, modify, or destroy data.
From the tool's definition Tool retrieves Docker Hub image metadata (last push, pull count, tags, size) with no modification or execution capability. The description explicitly states it is "for container audits and supply-chain research," which are informational queries.
Attacks that exploit this kind of access
The rule that runs lookup_dockerhub safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GoCreative Agent API, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_dockerhub, this is the rule to start with:
lookup_dockerhub 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 GoCreative Agent API, apply this rule, and every lookup_dockerhub call is checked against it from then on.
Questions about lookup_dockerhub
Get Docker Hub image metadata (last push, pull count, tags, size). Use for container audits and supply-chain research. Example call: {"image": "library/postgres"} Cost: $0.005–$0.05 USDC on Base per call. It is categorised as a Read tool in the GoCreative Agent API MCP Server, which means it retrieves data without modifying state.
lookup_dockerhub accepts 1 parameter: image. Required: image. The full parameter table on this page comes from the server's own tool schema.
Register the GoCreative Agent API MCP server in PolicyLayer and add a rule for lookup_dockerhub: 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 GoCreative Agent API. Nothing to install.
lookup_dockerhub 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 lookup_dockerhub 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 lookup_dockerhub. 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.
lookup_dockerhub is provided by the GoCreative Agent API MCP server (https://api.gocreativeai.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
