WHAT IT DOES

What lookup_uuid does on GoCreative Agent API

AI agents use lookup_uuid to commit financial operations through GoCreative Agent API, usually the final step of a payment, billing, or trading workflow. A call moves real money.

Parameter	Type	Required	Description
`query_string`	string	—

Parameters from the server's own tool schema.

RISK

Why lookup_uuid is rated Critical

Although the functional action (generating UUIDs) is trivially a Read/Execute operation with no side effects on external data, every call incurs a real financial transaction in USDC on Base. Per the rules, Financial is the most severe applicable category when money is committed, regardless of the underlying operation's data impact.

From the tool's definition Cost: $0.005–$0.05 USDC on Base per call. x402 + USDC on Base (server description). Each invocation commits a micro-payment in USDC.

RECOMMENDED RULE

The rule that runs lookup_uuid 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_uuid, this is the rule to start with:

lookup_uuid Approval-gated

Any call to lookup_uuid is blocked until a human approves it. The rest of the server keeps working.

FAQ

Questions about lookup_uuid

What does the lookup_uuid tool do? +

Generate v4 UUIDs. Pass ?count=N as query. Use for ID-generation agents. Example call: {"query_string": "count=5"} Cost: $0.005–$0.05 USDC on Base per call. It is categorised as a Financial tool in the GoCreative Agent API MCP Server, which means it involves financial transactions. Block by default and require explicit approval.

What parameters does lookup_uuid accept? +

lookup_uuid accepts 1 parameter: query_string. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on lookup_uuid? +

Register the GoCreative Agent API MCP server in PolicyLayer and add a rule for lookup_uuid: 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.

What risk level is lookup_uuid? +

lookup_uuid is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit lookup_uuid? +

Yes. Add a rate_limit block to the lookup_uuid 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.

How do I block lookup_uuid completely? +

Set action: deny in the PolicyLayer policy for lookup_uuid. 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.

What MCP server provides lookup_uuid? +

lookup_uuid 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.
