About Senseca PRO thermometer

An unofficial MCP server for reading live measurements from Senseca PRO 111 and PRO 115 Pt100 thermometers over USB. It provides temperature and resistance readings, device details, sampling statistics, and optional write operations for clock and location labels.

Key features

  1. 01Read temperature with unit and timestamp
  2. 02Read Pt100 resistance
  3. 03Sample readings with summary statistics
  4. 04Retrieve model, firmware, and battery details
  5. 05Optionally set clock and location labels

Use cases

  1. 01Check a connected thermometer's current temperature
  2. 02Collect readings over a timed interval
  3. 03Inspect device and battery information
  4. 04Set instrument time or a location label

MCP support

Exposes thermometer readings and device information as tools to MCP clients. Clock and location-label tools are available when write access is enabled.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
SENSECA_PORTSerial port of the instrument, e.g. /dev/ttyACM0 or COM3. Auto-detected if not set.
SENSECA_PINSecretInstrument PIN, only needed if its protected mode is enabled
SENSECA_ALLOW_WRITESet to 1 to enable tools that change instrument settings (clock, location labels)

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project 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

ToolDescription
read_temperatureCurrent temperature with unit (°C/°F/K, as set on the instrument) and UTC timestamp
read_resistanceCurrent Pt100 resistance in ohm
sample_temperatureReadings over a period (max 600 s, interval ≥ 0.5 s) with min/max/mean/stdev
get_device_infoModel, serial number, firmware, instrument clock, battery level

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

ToolDescription
set_device_clockSet the instrument clock (default: this computer's time)
set_location_nameRename 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….

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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
