LabJack T-series DAQ MCP Server

Let an AI agent read analog inputs, stream waveforms, read thermocouples, check digital lines and (with your permission) set DACs and digital outputs on LabJack T4, T7/T7-Pro and T8 DAQ devices through LabJack's official LJM library. Its 12 documented tools cover device, analog, inputs, digital.

People who work with device, analog and inputs and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

One of 32 MCP servers published from k-dense-ai/lab-instrument-mcps. Stars and repository activity are shared across all of them. See all 32 →

01 · Install LabJack T-series DAQ

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-e -- uvx labmcp-labjack

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-e": {
      "command": "uvx",
      "args": [
        "labmcp-labjack"

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-09-25 - young repo, little track record yet

license Apache-2.0 - declared in the repository

pypi package labmcp-labjack - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.K-Dense-AI is GitHub-verified and matches the repo owner

03 · What LabJack T-series DAQ can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

g. after it was power cycled or a cable was re-plugged), and set an analog output (DAC0/DAC1) to a DC voltage. The output stays at this value until changed or set_outputs_safe is called.

Capability map

Tools grouped from the project's README - what LabJack T-series DAQ lets an agent do.

read & search

4 tools - e.g. Return the most recent raw commands sent to / replies received from the instrument (newest last). Useful for debugging and for recording what was done.; Report which instrument is connected (identity…

get_command_log · get_connection_info · read_analog_inputs · read_thermocouple

Device

2 tools - e.g. Identify the connected LabJack (model, serial, firmware, connection) and list what it offers: analog inputs, valid input ranges, resolution indices, DAC range, ; Read the LabJack's internal temperature…

get_device_info · read_device_temperature

Digital

2 tools - e.g. Report the logic level and direction (input/output/analog) of digital I/O lines.; Make a digital line an output and drive it high (3.3 V) or low (0 V).

read_digital_inputs · set_digital_output

Reconnect

1 tool - e.g. Close and re-open the connection to the instrument (e.g. after it was power cycled or a cable was re-plugged).

reconnect

update

1 tool - e.g. Put the outputs in a safe state: stop any stream, set DAC0 and DAC1 to 0 V, and release every digital line this server drove (plus the safe_dio option lines) to

set_outputs_safe

Stream

1 tool - e.g. Acquire a hardware-timed waveform on one or more analog inputs (LJM stream mode) and return per-channel statistics plus a downsampled waveform; optionally save

stream_analog

create & write

1 tool - e.g. Set an analog output (DAC0/DAC1) to a DC voltage. The output stays at this value until changed or set_outputs_safe is called.

Limitations (from the README)

- Model differences are enforced. Valid input ranges (AIN_RANGE) and resolution indices come from LabJack's register map: T7 ±10/±1/±0.1/±0.01 V and index 0-8 (T7-Pro 0-12, but 9-12 cannot stream); T8 ±11 … ±0.018 V and index 0-16 (one index shared by all inputs); T4 fixed ranges (AIN0-3 ±10 V, AIN4-11 0-2.5 V) and index 0-5. DAC range: T4/T7 0-5 V, T8 0-10 V. - Settings persist. Range, resolution and differential se

06 · LabJack T-series DAQ FAQ

Is LabJack T-series DAQ still maintained?

Yes - as of 2026-09-30, its last commit was 2026-09-26. We re-verify nightly.

What can LabJack T-series DAQ do?

g. after it was power cycled or a cable was re-plugged), and set an analog output (DAC0/DAC1) to a DC voltage. The output stays at this value until changed or set_outputs_safe is called.

How do I install LabJack T-series DAQ?

Run `uvx labmcp-labjack`. You can also paste the ready-made client config above.

Does LabJack T-series DAQ run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
