About Body Metrics
Convert height and weight, compute BMI, TDEE and protein targets with error bounds
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Tools
1| Parameter | Type | Required | Description |
|---|---|---|---|
| age | number | Yes | Years, 15-100. Outside that the equations do not apply. |
| sex | enum | Yes | Required by the BMR equations, which are fitted separately.male | female |
| height | string | Yes | Height WITH a unit. Accepts 178cm, 1.78m, 5'10", 5 ft 10 in, 70in. A bare number is REFUSED because it is ambiguous. |
| weight | string | Yes | Weight WITH a unit. Accepts 75kg, 165lb, 11st 8lb. A bare number is REFUSED. |
| activity | enum | No | Activity band, default sedentary. This is the LARGEST source of error in the estimate — most people overestimate. If between two bands, take the lower.sedentary | light | moderate | active | extreme |
| targetBmi | number | No | Target BMI, 15-40, to compute a goal weight. |
| proteinGoal | enum | No | Which protein guidance range to report. Default maintenance.maintenance | active | strength | deficit |
| bodyFatPercent | number | No | Optional but worth supplying: adds the Katch-McArdle estimate, which uses lean mass, and moves the protein target onto lean mass. |
| dailyDeficitKcal | number | No | Daily deficit, to estimate a timeline. The timeline is a lower bound. |

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
