AI agents call get_material_consumption_history to retrieve information from Kiln without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves consumption history metrics from a 3D printer system—a passive, non-destructive read operation. Even if misused by an AI agent, it can only expose historical consumption data without affecting printer operations, material stocks, or system state. No side effects, no modifications, no execution of external commands.
From the tool's definition Tool name 'get_material_consumption_history' indicates retrieval of historical data with no modification capability. The prefix 'get_' is characteristic of read-only query operations.

get_material_consumption_history is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_material_consumption_history rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_material_consumption_history. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_material_consumption_history is provided by the Kiln MCP server (codeofaxel/Kiln). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
