AI agents call recent_events 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 name 'recent_events' is a typical read operation pattern used to query or fetch historical data. Given the empty description, confidence is moderately reduced, but in the context of 3D printer management tools, event retrieval is a standard non-destructive query operation with no side effects. Blast radius is low as it only exposes observational data about printer state and history.
From the tool's definition Tool name 'recent_events' with empty description suggests it retrieves historical event logs or status records from 3D printer control systems (OctoPrint, Moonraker, Bambu, Prusa, Elegoo).
Attacks that exploit this kind of access
recent_events. It is categorised as a Read tool in the Kiln MCP Server, which means it retrieves data without modifying state.
Register the Kiln MCP server in PolicyLayer and add a rule for recent_events: 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.
recent_events 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 recent_events 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 recent_events. 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.
recent_events 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.
