LabMCP

Open-source MCP servers that let AI agents operate real lab instruments, with safety limits, read-only modes, audit trails, and a simulator for every instrument.

Requirements

01 · What it does

32 servers (411 tools): balances, hotplate stirrers, syringe pumps, spectrometers, potentiostats, SourceMeters, bench power supplies, Rigol oscilloscopes and more
Practice mode on every connector (--simulate), with no instrument connected
Read-only mode (--read-only) and per-experiment limits such as --limit max_temperature_c=60
Generic SCPI, Modbus TCP/RTU, EPICS and SiLA 2 connectors for instruments without their own server
Command log (get_command_log) and an optional --audit-log file

02 · Install

$ claude mcp add balance -- uvx labmcp-mettler-toledo --simulate

Install uv first (README has the one-line installer for Mac/Linux and Windows)
Each instrument family is its own package: swap labmcp-mettler-toledo for the name in the README's Supported instruments table
Real instrument: find its address with `uvx labmcp ports`, test with `uvx labmcp-mettler-toledo --address COM3 --check`, then replace "--simulate" with "--address", "COM3"
Cursor uses the same mcpServers format in .cursor/mcp.json or ~/.cursor/mcp.json (docs/clients.md)
The README marks most connectors "simulated": built from the manufacturer's manual, not yet confirmed on a real instrument by a user

03 · Client config (from README)

{
  "mcpServers": {
    "balance": {
      "command": "uvx",
      "args": [
        "labmcp-mettler-toledo",
        "--simulate"
      ]
    }
  }
}

Install steps taken from the project README (its recommended path first). Placeholders are the maintainer's. Not bench-tested by HardwareMCP yet.
