Ultrahuman MCP Server

A Model Context Protocol (MCP) server for fetching health and fitness metrics from the Ultrahuman API, including heart rate, sleep data, steps, temperature, HRV, and more. The ultrahuman mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Its toolset

Everything the assistant can do here goes through one of these:

• Email — Send a request to support@ultrahuman.com
• ultrahuman_metrics — Fetches health and fitness metrics from the Ultrahuman API for a specific date. The user email is configured via environment variable, so you only

Configuration

You will need 2 environment variables: ULTRAHUMAN_AUTH_TOKEN, ULTRAHUMAN_USER_EMAIL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the ultrahuman mcp mcp server does with a few real requests.

When to reach for it

Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Ultrahuman MCP's toolset — Email, ultrahuman_metrics — is a fair guide to whether it matches your workflow. It is maintained by Monasterolo21; worth a glance at recent repository activity before you build anything load-bearing on it.
