Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account shaag7967 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Reads live temperature and Pt100 resistance from a Senseca PRO 111/115 USB thermometer, with sampling and device info.

What you can do: Read the current temperature with its unit and UTC timestamp, or the Pt100 probe resistance in ohm
Record readings over a period (up to 600 s, interval at least 0.5 s) and get min/max/mean/stdev plus all samples
Inspect the instrument: model, serial number, firmware, clock and battery level
With write mode enabled, set the instrument clock or rename one of the 20 location labels
When to use it: Useful when an assistant should work with real measurements from a Senseca PRO handheld thermometer over USB — for example logging a temperature series, checking probe resistance, or reading device status during lab or field work.
Requirements: Local process run with uvx; Python 3.10 or newer and uv. The instrument must be switched on and connected via USB-C (PRO 115 set to COM interface mode). Optional SENSECA_PORT to pick the serial port, otherwise auto-detected; on Linux the user must be in the dialout group. SENSECA_PIN only if the instrument's protected mode is on.

Before you install

Write tools (clock, location labels) are off unless SENSECA_ALLOW_WRITE is set to 1; enabling them lets the assistant change instrument settings. SENSECA_PIN is a secret for protected mode. Only one program can use the serial port at a time, so close ProXware or terminal programs. The USB port is not galvanically isolated and can shift readings with grounded media. Unofficial project, not affiliated with Senseca.

Installation

In SourceWeft

Open Senseca PRO thermometer in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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:

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….

{  "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

bash

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

To check a real instrument, connect it and run:

bash

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

uv run python scripts/hardware_test.py               # read-only checks, no interactionuv 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.
