Atlas Scientific EZO Sensors MCP Server

Let an AI agent read, calibrate and log Atlas Scientific EZO™ sensor circuits (pH, ORP, dissolved oxygen, conductivity, RTD temperature, humidity, CO2 and pressure) over their documented UART command set. Useful for bioreactors, cell-culture media, fermentation, hydroponics, aquaculture and environmental monitoring. Its 13 documented tools cover calibration, log, compensation.

People who work with calibration, log and compensation 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 Atlas Scientific EZO Sensors

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-b -- uvx labmcp-atlas-ezo

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-b": {
      "command": "uvx",
      "args": [
        "labmcp-atlas-ezo"
      ]
    }
  }
}

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-atlas-ezo - 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 Atlas Scientific EZO Sensors can do

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

What you can build

With this server connected, an agent can delete all stored calibration data (Cal,clear). g. after it was power cycled or a cable was re-plugged), and set the sample temperature used to compensate pH, EC or DO readings (T,n.

Tools grouped from the project's README - what Atlas Scientific EZO Sensors lets an agent do.

read & search

5 tools - e.g. Report how many calibration points are stored and what that means for this circuit type; for pH also the probe slope (acid/base % of ideal and zero offset in mV; Return the most recent raw commands sent…

update

4 tools - e.g. DO circuits only: set salinity compensation (irrelevant below ~2500 µS/cm) and/or atmospheric pressure compensation (default 101.3 kPa; lower at altitude). Neit; Turn the circuit's status LED on or off.…

Calibrate

1 tool - e.g. Store one calibration point. The probe must already be in the named standard (buffer, air, dry, ...) with a stable reading. Point names are validated per circui

calibrate

Clear

1 tool - e.g. Delete all stored calibration data (Cal,clear). pH/ORP/DO/EC/RTD return to uncalibrated; CO2/PRS return to their factory calibration. The probe must be recalibr

clear_calibration

Log

1 tool - e.g. Record a series of readings (e.g. to watch a probe stabilise before calibrating, follow pH or DO in a bioreactor, or log temperature). Returns every point plus

log_series

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).

Limitations (from the README)

- Units per circuit: pH; ORP in mV; DO in mg/L and (if enabled with O,%,1) % saturation; EC in µS/cm plus TDS (ppm), salinity (PSU) and specific gravity when enabled; RTD in its configured scale (°C/K/°F); HUM in %RH plus air temperature and dew point (°C) when enabled; CO2 in ppm (+ internal temperature); PRS in its configured unit (psi, atm, bar, kPa, inH2O, cmH2O). Which outputs are enabled is read from the circui

06 · Atlas Scientific EZO Sensors FAQ

Is Atlas Scientific EZO Sensors still maintained?

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

What can Atlas Scientific EZO Sensors do?

How do I install Atlas Scientific EZO Sensors?

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

Does Atlas Scientific EZO Sensors 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.
