Why get_material is rated Low
This is a simple query operation that retrieves information about the current material status from Kiln's tracker. It performs no mutations, does not trigger physical operations, and does not expose sensitive financial or destructive capabilities. The information retrieved (material type/status) is operational data useful for monitoring but not itself a security-sensitive asset in this context.

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