Wellness CGM
Pair cgm_meal_response with wellness-nourish meal logs to get 'this meal hit a 72 mg/dL spike at 45min — try protein-first next time'. Levels charges $199/mo for this; here it's an MCP. Sandbox mode lets any agent demo without setup.
Biohackers, T2D users, athletes optimizing carb timing, anyone who wants their AI agent to see meal→glucose response in real time.
