Computes BMI, basal metabolic rate, total daily energy expenditure, and protein targets from height, weight, age, sex and activity level. Uses multiple standard equations and reports uncertainty ranges. Accepts flexible unit formats and rejects implausible values.

Example request: "What's my daily calorie burn and protein target based on my height, weight, and activity level?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Body Metrics to help me. It is a free service with an MCP server at https://body-metrics.gumballtools.com/api/mcp. It does not need an API key. Ask me before you share anything with it."

We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
