What lookup_packagist does on GoCreative Agent API
AI agents call lookup_packagist 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.

pkg | string | Yes |
Parameters from the server's own tool schema.
Why lookup_packagist is rated Low
This is a pure read operation that queries a public package registry (Packagist/Composer) for metadata about PHP packages. It has no side effects, does not execute code, and does not alter any state. While the server charges per call (a financial model), the tool itself performs only a data retrieval operation.
From the tool's definition Tool description explicitly states "Get Packagist (PHP) package metadata" and the example call queries package information. The use case is "PHP-dependency audits," which are information-gathering activities.
Attacks that exploit this kind of access
The rule that runs lookup_packagist 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_packagist, this is the rule to start with:
lookup_packagist 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_packagist call is checked against it from then on.
