Pfeiffer Vacuum Gauge Controller MCP Server

Let an AI agent read and log chamber and foreline pressures, identify the connected gauges, change the pressure unit and switch ionisation gauges on and off (with a pressure check) on Pfeiffer Vacuum TPG total-pressure gauge controllers. Its 11 documented tools cover gauge, log, pressure.

People who work with gauge, log and pressure 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 Pfeiffer Vacuum Gauge Controller

Claude Code

claude mcp add k-dense-ai-lab-instrument-mcps-servers-p -- uvx labmcp-pfeiffer-tpg

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "k-dense-ai-lab-instrument-mcps-servers-p": {
      "command": "uvx",
      "args": [
        "labmcp-pfeiffer-tpg"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

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-pfeiffer-tpg - 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

Limitations (from the README)

- Switching ionisation gauges on is the hazard. Hot-cathode (Bayard-Alpert) filaments can burn out and cold-cathode (Penning) gauges contaminate when operated at high pressure. set_gauge_power(on=True) requires a reading with status ok at or below max_switch_on_pressure_mbar from the gauge itself or from reference_channel on the same vacuum. An underrange reading from a Pirani is not accepted as proof (what the contr
