WHAT IT DOES

What failure_history does on Kiln

AI agents call failure_history to retrieve information from Kiln without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why failure_history is rated Low

This tool queries and displays existing failure records. It performs no creation, modification, deletion, code execution, or financial operations. The verb 'View' and the retrieval of historical data confirm a Read classification. The low severity reflects that accessing failure history poses minimal risk even if misused by an agent.

From the tool's definition Tool name 'failure_history' and description 'View failure history for a printer or failure type' indicate a read-only operation that retrieves historical data without modification or side effects.

RECOMMENDED RULE

The rule that runs failure_history 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 failure_history, this is the rule to start with:

failure_history Allowed

failure_history is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "failure_history": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Kiln, apply this rule, and every failure_history call is checked against it from then on.
