Ocean Insight Spectrometer MCP Server

Let an AI agent acquire spectra, set or auto-tune the integration time, store dark and reference spectra, and measure absorbance and transmittance with peak positions and FWHM on Ocean Insight (Ocean Optics) spectrometers. It works through the open-source python-seabreeze library. Its 16 documented tools cover detector, integration, time, cooling.

People who work with detector, integration and time 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 Ocean Insight Spectrometer

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-c -- uvx labmcp-ocean-spectrometer

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-c": {
      "command": "uvx",
      "args": [
        "labmcp-ocean-spectrometer"
      ]
    }

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-ocean-spectrometer - 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 Ocean Insight Spectrometer can do

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

What you can build

An agent gets 16 documented tools spanning detector, integration, time, cooling, including acquire_spectrum, auto_integration_time, detector_cooling_off, find_peaks.

Tools grouped from the project's README - what Ocean Insight Spectrometer lets an agent do.

Limitations (from the README)

- Raw counts. Intensities are detector counts, not irradiance. Radiometric calibration is out of scope. - Saturation is judged on the raw ADC counts of every averaged scan: a pixel is saturated at ≥ 98 % of max_intensity. Saturated pixels are flagged, and they're excluded from absorbance/transmittance (with boxcar smoothing, so are the pixels within the boxcar half width of them). seabreeze notes that some detectors

06 · Ocean Insight Spectrometer FAQ

Is Ocean Insight Spectrometer still maintained?

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

What can Ocean Insight Spectrometer do?

An agent gets 16 documented tools spanning detector, integration, time, cooling, including acquire_spectrum, auto_integration_time, detector_cooling_off, find_peaks.

How do I install Ocean Insight Spectrometer?

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

Does Ocean Insight Spectrometer 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.
