The severity is low because misuse would at worst expose package structure information, posing minimal risk to systems or data integrity.

Attacks that exploit this kind of access
The rule that runs package-show-dependencies safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Http, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For package-show-dependencies, this is the rule to start with:
package-show-dependencies 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 Http, apply this rule, and every package-show-dependencies call is checked against it from then on.
