Quickstart - skcal

Open app.skcal.fit and sign in with Google or an email magic link. Your data is scoped to your account.

2. Set your targets

On the web app, log a weigh-in and set your daily calorie + protein targets and goal weight. The dashboard tracks everything against these.

3. Log from wherever you are

CLI
MCP (agents)
HTTP API

npm install -g @skeptrune/skcal
skcal login
skcal weight log 158.2 --note "morning, fasted"
skcal meal describe "chicken breast + toum, skipped the salad"
skcal status

See Install the CLI for the full command list.

claude mcp add --transport http skcal https://app.skcal.fit/mcp

Then ask your agent things like “what’s my status today?” or “log 160 lb.” See Install the MCP server for Claude, Claude Code, and ChatGPT.

Every request is scoped to your account (see Authentication). The scale-ingest endpoint takes a bearer token:

curl -X POST https://app.skcal.fit/api/ingest/weight \
  -H "Authorization: Bearer $INGEST_TOKEN" \
  -H "content-type: application/json" \
  -d '{"weightKg": 72.6}'

Browse everything in the API reference.
