Insulin on Board Decay Calculator

Insulin on Board Decay Calculator MCP Connector for Claude

A+

Calculate remaining active insulin and assess stacking risk.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides deterministic tools to calculate Insulin on Board (IOB) using a linear decay model. It helps prevent insulin stacking by assessing the risk of hypoglycemia. Use calculate_iob_metrics to find current insulin levels and predicted blood glucose lowering potential, or assess_stacking_risk to check if a new dose is safe. You can also use get_iob_at_specific_times to project future insulin levels.

I took 5 units of insulin 60 minutes ago. The duration is 240 minutes and my ISF is 50. What is my current IOB and risk?

Your current IOB is 3.75 units. The effective blood glucose lowering potential is 187.5 mg/dL. Your stacking risk is High Stacking Risk.

Check if I can take more insulin. I have 0.2 units of insulin left from a dose taken 200 minutes ago.

Your stacking risk is Low Stacking Risk.

What will my insulin levels be in 30 and 60 minutes if I took 4 units 30 minutes ago with a 240 minute duration?

In 30 minutes (60 mins total), your IOB will be 3.0 units. In 60 minutes (90 mins total), your IOB will be 2.25 units.

The server uses a linear decay model where insulin activity decreases at a constant rate until it reaches zero at the end of its duration of action.
