This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add labmcp-ms-worklist -- uvx labmcp-ms-worklist
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "labmcp-ms-worklist": {
      "args": [
        "labmcp-ms-worklist"
      ],
      "command": "uvx"
    }
  }

This one needs environment variables set before it will start: LABMCP_ADDRESS (Instrument address, e.g. serial:///dev/ttyUSB0 or tcp://192.168.1.50:5025), LABMCP_SIMULATE (Set to 1 to use the built-in simulator (no hardware)), LABMCP_READ_ONLY (Set to 1 to disable all state-changing tools), LABMCP_LIMITS (Safety limit overrides, e.g. max_temperature_c=80). The author declared them in the registry entry; get the values from the project itself.

LC-MS Worklist Builder — questions

Answers built from our own checks of this server.

Why is there no uptime for LC-MS Worklist Builder?
LC-MS Worklist Builder runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package labmcp-ms-worklist was installed 174 times last week.
How do I connect LC-MS Worklist Builder?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls labmcp-ms-worklist straight from pypi; nothing to host, nothing to sign up for.
How many people use LC-MS Worklist Builder?
The pypi package labmcp-ms-worklist was installed 174 times in the last week. Week over week that is -32%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is LC-MS Worklist Builder open source?
Yes — it is published under the Apache-2.0 licence, written in Python and 19 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
