NI-DAQmx DAQ Devices MCP Server

Let an AI agent acquire voltages and thermocouple temperatures, read digital lines and (with your permission) set analog and digital outputs on National Instruments DAQ hardware through the official NI-DAQmx driver and its Python API. Its 11 documented tools cover analog, digital, lines.

People who work with analog, digital and lines 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 NI-DAQmx DAQ Devices

Claude Code

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

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-e": {
      "command": "uvx",
      "args": [
        "labmcp-ni-daqmx"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

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-ni-daqmx - 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

Digital

2 tools - e.g. Read the logic level of digital lines.; Drive digital output lines high or low. The lines keep their level after the call until changed or set_outputs_safe is called.

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).

update

1 tool - e.g. Put the device's outputs in a safe state: every analog output to 0 V (or the bottom of its range if 0 V is not in it) and, by default, every digital line this s

set_outputs_safe

Limitations (from the README)

- Every tool call is one short DAQmx task (create channels, configure timing, read or write, close), as in NI's examples, so the server never holds the device reserved between calls. Another program using the device at the same time causes a clear "resource reserved" error (-50103). Output and digital-line tasks are serialised separately from acquisitions, so set_outputs_safe (and write_analog) never wait for a runni

06 · NI-DAQmx DAQ Devices FAQ

Is NI-DAQmx DAQ Devices still maintained?

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

What can NI-DAQmx DAQ Devices do?

How do I install NI-DAQmx DAQ Devices?

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

Does NI-DAQmx DAQ Devices 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.
