What You'll Need

Set these up before or after installing:

Serial port of the instrument, e.g. /dev/ttyACM0 or COM3. Auto-detected if not set.Optional

Environment variable: SENSECA_PORT

Instrument PIN, only needed if its protected mode is enabledRequired

Environment variable: SENSECA_PIN

Set to 1 to enable tools that change instrument settings (clock, location labels)Optional

Environment variable: SENSECA_ALLOW_WRITE

How to Install

From the project's GitHub README.

mcp-server-senseca-pro

An MCP server that lets AI assistants read live measurements from a Senseca PRO 111 / PRO 115 handheld Pt100 thermometer connected via USB.

Unofficial project, not affiliated with or endorsed by Senseca. Tested with a PRO 111, firmware V1.4.3.0, interface protocol V1.0.0.1.

Tools

Tool	Description
`read_temperature`	Current temperature with unit (°C/°F/K, as set on the instrument) and UTC timestamp
`read_resistance`	Current Pt100 resistance in ohm
`sample_temperature`	Readings over a period (max 600 s, interval ≥ 0.5 s) with min/max/mean/stdev
`get_device_info`	Model, serial number, firmware, instrument clock, battery level

With --allow-write two more tools are available:

Tool	Description
`set_device_clock`	Set the instrument clock (default: this computer's time)
`set_location_name`	Rename one of the 20 location labels

The server cannot change calibration or adjustment data; the instrument does not offer that over its serial interface.

Requirements

Python ≥ 3.10 and uv
The instrument switched on and connected via USB-C. On the PRO 115 set Settings → USB mode to COM interface.
Linux: your user must be in the dialout group (sudo usermod -aG dialout $USER, then log in again).
Windows / macOS: no extra setup; the port shows up as COMx or /dev/cu.usbmodem….

Configuration

Claude Code

claude mcp add senseca-pro -- uvx mcp-server-senseca-pro

Claude Desktop and other clients

{
  "mcpServers": {
    "senseca-pro": {
      "command": "uvx",
      "args": ["mcp-server-senseca-pro"]
    }
  }
}

Options

Option	Environment variable	Default
`--port PORT`	`SENSECA_PORT`	auto-detect
`--allow-write`	`SENSECA_ALLOW_WRITE=1`	off
`--log-level LEVEL`	`SENSECA_LOG_LEVEL`	`WARNING`
—	`SENSECA_PIN`	none; needed only if the instrument's protected mode is on

Auto-detection looks for USB ID 0483:5740 and only accepts a port whose device reports manufacturer senseca. If several instruments are connected, set the port explicitly; on Linux prefer the stable /dev/serial/by-id/… path.

Only one program can use the serial port at a time. Close ProXware or terminal programs while the server is running.

Measurement notes

Instrument accuracy: ±0.05 °C or ±0.06 % of reading (whichever is higher) ±1 digit, probe not included.
The USB port is not galvanically isolated. With a probe touching a grounded medium, the USB connection can shift the reading. Compare readings with and without USB, and use a USB isolator if they differ (see the instrument manual, section 7.2).

Development

uv sync
uv run pytest                                   # tests use a simulated instrument
npx @modelcontextprotocol/inspector uv run mcp-server-senseca-pro   # try the tools interactively

To check a real instrument, connect it and run:

uv run python scripts/hardware_test.py               # read-only checks, no interaction
uv run python scripts/hardware_test.py --reconnect   # also unplug/replug USB when asked

The script only sends read commands. See --help for the PIN test.

The serial protocol is described in docs/protocol.md.
