LC-MS Worklist Builder MCP Server

Let an AI agent build LC-MS sample queues (worklists, sequences, batches) and export them as import files for Waters MassLynx, SCIEX OS, Agilent MassHunter Acquisition and Thermo Xcalibur. The agent can lay out samples on a tray, insert blanks and QCs, randomise the run order with a recorded seed, check the list for mistakes, convert an existing file from one vendor to another, and write the file for a person to…. Its 12 documented tools cluster into read & search, create & write, export, import.

People who work with worklist 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 LC-MS Worklist Builder

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-c -- uvx labmcp-ms-worklist

Claude Desktop / Cursor / VS Code - add to config

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

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-ms-worklist - 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

Import

1 tool - e.g. Parse an existing MassLynx, SCIEX OS, MassHunter or Xcalibur import file from the output folder into a draft, so it can be validated, edited or exported in anot

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).

Validate

1 tool - e.g. Check a draft against the target format: required fields, duplicate data-file names, characters Windows does not allow in file names, tray/vial position format

Limitations (from the README)

- Drafts live in memory. reconnect (or restarting the server) discards them. In --simulate it also deletes the temporary folder. Export files you want to keep. - By default, export_worklist also writes .provenance.json next to the worklist (for example Plasma.csv.provenance.json). Like the worklist itself, it is never overwritten unless overwrite=true. It contains the operation history, the randomisation seed and the
