skcal tracks weigh-ins, body measurements, and nutrition, and gives you a daily snapshot of where you stand against your targets. It’s built to be driven by software: a typed HTTP API, a CLI, and a remote MCP server so your agents can log and query your data.

Quickstart

Sign in and make your first calls.

Install the CLI

@skeptrune/skcal — log and query from your terminal.

Install the MCP server

Connect skcal to Claude, Claude Code, or ChatGPT.

API reference

Every endpoint, generated from the OpenAPI spec.

What you can do

  • Log weigh-ins (with optional body-fat % and notes), body measurements, and meals.
  • Estimate meal macros from a photo or a plain-text description.
  • Track calories and protein against daily targets, and weight against a goal.
  • Ask the agent for a blunt read on what to eat, grounded in your real numbers.
