Why lookup_npm is rated Low
lookup_npm retrieves publicly available package metadata from npm registry. It has no side effects, does not modify or delete data, does not execute code, and does not involve financial transactions beyond the pay-per-call API fee. The tool is a straightforward read operation returning informational fields about a package.
From the tool's definition Tool description states it "Get npm package metadata (latest version, weekly downloads, repo, license, maintainers)" and is used for "OSS health checks or dependency audits".
Attacks that exploit this kind of access
The rule that runs lookup_npm 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_npm, this is the rule to start with:
lookup_npm 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_npm call is checked against it from then on.
