PicoScope 5000A/B series oscilloscope (pico_mcp.scope.Scope)

PicoScope 5000A/B series oscilloscope (pico_mcp.scope.Scope), adapted from schimmilab/pico-mcp. It reads connected, variant, serial, resolution_bits and 1 more; sets channel_a_enabled, channel_a_coupling, channel_a_range_v, channel_b_enabled and 8 more; runs set_signal_generator, stop_signal_generator and capture_block. set_signal_generator: configure the built-in signal generator (AWG) through ps5000aSetSigGenBuiltInV2. A hardware driver: the market serves its fake backend, so no instrument is needed.

Install

Three ways to run this device. Each one serves its fake backend: no instrument, no simulator install and no upstream checkout.

OpenAI4S (one command)

shell
openai4s lab add labs/schimmilab__pico-mcp

Installs the device into the OpenAI4S Lab on its fake backend and starts it. First time? See setup below.

Or, in the workbench, open the Lab tab → Market → Install.

Standalone MHS endpoint

shell
git clone --depth 1 https://github.com/PKU-YuanGroup/OpenMHS.git && cd OpenMHS
PYTHONPATH=MHS/sdk/src python3 -m mhs serve labs/schimmilab__pico-mcp --port 7400
# in a second terminal, from the same directory:
PYTHONPATH=MHS/sdk/src python3 -m mhs describe --endpoint http://127.0.0.1:7400

Serves the device as an MHS endpoint on port 7400 from an OpenMHS clone (Python 3.10 or later, standard library only); describe prints what it offers.

Any MCP host (Claude Desktop, Cursor, …)

mcp configuration
{
  "mcpServers": {
    "pico-mcp": {
      "command": "python3",
      "args": [
        "-m",
        "mhs",
        "serve",
        "labs/schimmilab__pico-mcp",

      "env": {
        "PYTHONPATH": "/path/to/OpenMHS/MHS/sdk/src"
      }
    }
  }
}

Add this server to the host's MCP configuration and replace /path/to/OpenMHS with the path of your OpenMHS clone. The host starts the server and talks to it on stdin and stdout.

What it does

Measures

  • connected
  • variant
  • serial
  • resolution_bits
  • max_adc

Adjusts

  • channel_a_enabled
  • channel_a_coupling
  • channel_a_range_v
  • channel_b_enabled
  • channel_b_coupling
  • channel_b_range_v
  • channel_c_enabled
  • channel_c_coupling
  • channel_c_range_v
  • channel_d_enabled
  • channel_d_coupling
  • channel_d_range_v

Actions

set_signal_generator
Configure the built-in signal generator (AWG) through ps5000aSetSigGenBuiltInV2
stop_signal_generator
Turn the built-in signal generator off (DC at 0 V); the safe state, no input
capture_block
Capture one block on all enabled channels and return the scalar measurements

Names as the driver declares them. Units, limits and the safety declaration are in the package's REFERENCE.md.

First-time setup

The OpenAI4S workbench with the OpenMHS lab, from a source checkout:

shell
# OpenAI4S workbench with the OpenMHS lab (source checkout)
git clone --recursive https://github.com/PKU-YuanGroup/OpenAI4S.git
cd OpenAI4S && ./setup.sh && source .venv/bin/activate
openai4s lab add labs/schimmilab__pico-mcp
openai4s serve        # open the Lab tab

The standalone endpoint and the MCP server need only an OpenMHS clone and Python 3.10 or later. More in the market's getting-started guide and on the OpenAI4S host page.
