MCP

MCP is how an agent app calls Humanform on your Mac. The server is a local stdio process. Humanform still calculates millimetres on that Mac. The chat app may send tool results to its own cloud. Humanform does not.

On a Mac, open Settings → MCP. That screen can install the server in Cursor, copy a config snippet for Claude Desktop, and copy a Claude Code command. The command is the humanform-cli binary inside the app, with the argument mcp.

humanform-cli mcp

A config for other agent apps uses the same binary. Settings copies the real path on your Mac. The shape is:

{
  "mcpServers": {
    "humanform": {
      "type": "stdio",
      "command": "/path/to/Humanform.app/Contents/MacOS/humanform-cli",
      "args": ["mcp"]
    }
  }
}

Tools

Tool	What it does
`measurements`	Search the catalog. Returns catalog ids, display names, body group, and whether the measurement is included without Pro. It does not return millimetres.
`packs`	List presets and the catalog ids in each.
`predict`	Predict one measurement. Returns millimetres from the on-device grids.
`fit`	Share of an age or age band that meets every limit. Requires Humanform Pro.
`population`	Census-weighted sample for one measurement between a minimum and maximum in millimetres. Requires Humanform Pro.
`accommodate`	Solve limits for a preset or a measurement list so a target percent of people fit. Requires Humanform Pro.

predict needs a measurement. Country, gender, age, percentile, and unit are optional. Age is 1 through 88. Percentile is 1 through 99. Unit is mm, cm, or in. Omit country to use the app preference.

fit takes a list of constraints. Each constraint names a measurement and may set a lower and upper bound in millimetres.

accommodate presets are workstation, standingReach, cockpit, and apparel. Target fit percent defaults to 90. Presets are not standards certificates.

There is also a seated-workstation prompt that solves the seated workstation preset for an age band.

See Command line for the same commands in Terminal, Measurements for names, and Countries for codes.
