WHAT IT DOES

What lookup_gleif_ownership does on GoCreative Agent API

AI agents call lookup_gleif_ownership 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.

RISK

Why lookup_gleif_ownership is rated Low

Even though lookup_gleif_ownership only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs lookup_gleif_ownership 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_gleif_ownership, this is the rule to start with:

lookup_gleif_ownership Allowed

lookup_gleif_ownership is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GoCreative Agent API, apply this rule, and every lookup_gleif_ownership call is checked against it from then on.
