LabMCP: Let AI Assistants Run Your Lab Instruments

<!-- COUNTS:START --> <!-- COUNTS:END -->

LabMCP lets an AI assistant such as Claude operate your laboratory instruments. You describe what you want in plain language, and the assistant weighs, heats, stirs, pumps, measures and logs for you. It stays inside safety limits you set, keeps a record of every command, and has a practice mode that needs no hardware.

It supports balances, hotplate stirrers, syringe pumps, spectrometers, potentiostats, lock-in amplifiers, temperature controllers, vacuum gauges, flow controllers, biosensors, clinical analyzers and more. You don't need to know how to program. Setup means installing one free helper program and pasting a few lines into your AI app's settings.

Free and open source, built by K-Dense.

You:        Tare the balance, then heat the stirrer to 60 °C at 400 rpm and log the pH every
            30 s until it's stable. Tell me when to add the reagent.

Assistant:  [tares the balance → sets stirring to 400 rpm → sets heating to 60 °C → logs pH …]
            "pH has been 7.41 ± 0.01 for 3 minutes. Ready for the reagent."

💡 How it works

You  ──type──▶  AI app  ──▶  LabMCP connector  ──USB / serial / network cable──▶  Instrument
                 (Claude,       (runs on the computer
                  Cursor, …)     attached to the instrument)

• The AI app is where you type requests, e.g. Claude Desktop.
• A LabMCP connector is a small program that knows one family of instruments and its command language, so the AI never has to guess it. You add one connector per type of instrument. (Technically these are MCP servers, which is the term you'll see in the tables and docs.)
• MCP (Model Context Protocol) is the open standard that lets AI apps plug into tools like these. Think of it as USB for AI.
• The AI can only use the actions a connector offers, like "tare", "set temperature" or "read pH". In the docs these actions are called tools. The connector checks every request against your limits and refuses anything unsafe before it reaches the instrument.

🚀 Try it in 10 minutes (no instrument needed)

Each connector has a practice mode (a simulator) that behaves like the real instrument and gives realistic replies. Nothing is connected, so nothing can go wrong.
