What estimate_print_progress does on Kiln
AI agents call estimate_print_progress 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.
Why estimate_print_progress is rated Low
The tool name indicates passive monitoring/querying of print progress state rather than control, modification, or execution. Without a description, confidence is moderate, but the name strongly suggests a read operation that would retrieve current or projected print completion data from the printer without causing state changes.
From the tool's definition Tool name 'estimate_print_progress' suggests retrieval of print status information with no side effects. Description is empty, reducing confidence. Sibling tools like 'ams_status' and context of 3D printer monitoring support this classification.
Attacks that exploit this kind of access
The rule that runs estimate_print_progress 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 estimate_print_progress, this is the rule to start with:
estimate_print_progress 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 estimate_print_progress call is checked against it from then on.
Questions about estimate_print_progress

Register the Kiln MCP server in PolicyLayer and add a rule for estimate_print_progress: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kiln. Nothing to install.
estimate_print_progress 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 estimate_print_progress 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 estimate_print_progress. 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.
estimate_print_progress 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.
