Summary
Last night's sleep and heart rate arrive in the conversation instead of in an app you have to go and open.
ultrahuman_metrics is the entire server, and it takes a date, so a week's comparison is one call per day and there is no range or aggregate to ask for. That narrowness is also the appeal: one variable pair configured once, and the day's biometrics are available wherever the client is. Nothing writes back to the account.
What it is
A single-tool client for the Ultrahuman API that returns a day's health and fitness metrics for the configured user.
What you get
- Health and fitness metrics for a given date — heart rate, sleep, steps, temperature and other biometric measurements
- Date as the only argument, since the user email comes from the environment
Requirements
An Ultrahuman account with API access, supplied as ULTRAHUMAN_AUTH_TOKEN and ULTRAHUMAN_USER_EMAIL. The email is fixed by that variable, so the server reports on one user.
Setup effort
One command plus a key — npx -y ultrahuman-mcp, then supply credentials
