WHAT IT DOES

What napkin_generate_visual does on Freshdesk

AI agents invoke napkin_generate_visual to trigger actions in Freshdesk. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why napkin_generate_visual is rated High

This tool triggers an external AI service (Napkin AI) to perform a generation operation. It is not a simple read; it initiates an external process that produces output. No financial or destructive implications, but it executes an external operation whose effects depend on the input arguments.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs napkin_generate_visual safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Freshdesk, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For napkin_generate_visual, this is the rule to start with:

napkin_generate_visual Rate-limited

napkin_generate_visual stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
