calculate_insulin_dosage · T1D Manager MCP: Risk & Policy

WHAT IT DOES

What calculate_insulin_dosage does on T1D Manager

AI agents invoke calculate_insulin_dosage to trigger actions in T1D Manager. 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.

WHY IT NEEDS A POLICY

Why calculate_insulin_dosage needs a policy

Insulin dosage calculation directly influences medical decisions that, if incorrect, could result in life-threatening hypoglycemia or hyperglycemia. Even as a calculation tool (Read/Execute boundary), it triggers external-facing medical recommendations. The empty description lowers confidence, but the server context (T1D Manager, real-time CGM, insulin dosing) makes this a critical-severity tool.

From the tool's definition Tool name 'calculate_insulin_dosage' on a server managing Type 1 diabetes insulin dosing; description is empty and uninformative.
