MHS-5200A MCP Server

A Model Context Protocol (MCP) server for controlling MHS-5200A series signal generators (and compatible models such as MHS-5200P / MHS-5225A) via a serial connection.

Features

• Full Channel Control: Set frequency, amplitude, duty cycle, DC offset, phase, and waveform for both channels independently.
• Waveform Selection: Support for Sine, Square, Triangle, Sawtooth, and Arbitrary waveforms.
• Frequency Sweep: Configure and run linear or logarithmic frequency sweeps.
• Arbitrary Waveforms: Upload custom waveform data (2 048 points) to any of the 16 memory slots.
• Advanced Features: Control channel tracking, output inversion, and the internal power amplifier (if equipped).

Requirements

• Python >= 3.13
• mcp[cli] 2.x (v0.2.0 and later; use mhs5200a-mcp 0.1.x if you are pinned to mcp 1.x)

Installation

Using uv (recommended):

uv pip install mhs5200a-mcp

Or via pip:

pip install mhs5200a-mcp

Or from source:

git clone https://github.com/NaoNaoMe/mhs5200a-mcp.git
cd mhs5200a-mcp
uv sync

Configuration

Claude Desktop Config

Add the server to your claude_desktop_config.json:

{
  "mcpServers": {
    "mhs5200a-mcp": {
      "command": "uvx",
      "args": [
        "mhs5200a-mcp"
      ]
    }
  }
}

Tools Overview

Connection

• mhs5200_connect: Connect to the device via serial port (e.g., COM3, /dev/ttyUSB0).
• mhs5200_disconnect: Disconnect from the device.
• mhs5200_get_status: Get current settings for all channels.

Channel Control

• mhs5200_set_frequency: Set frequency in Hz (0.01 Hz – 25 MHz).
• mhs5200_set_amplitude: Set amplitude in volts peak-to-peak (0–15 V).
• mhs5200_set_waveform: Select waveform (SINE, SQUARE, TRIANGLE, SAWTOOTH_UP, SAWTOOTH_DOWN, ARB00–ARB15).
• mhs5200_set_duty_cycle: Set duty cycle percentage (0–99.9 %).
• mhs5200_set_offset: Set DC offset percentage.
• mhs5200_set_phase: Set phase offset between channels.
• mhs5200_set_invert: Invert waveform output.

Global Settings

• mhs5200_set_output: Enable or disable all outputs.
• mhs5200_set_tracking: Enable channel tracking (CH2 follows CH1).
• mhs5200_set_power_amp: Enable the internal power amplifier (if supported).

Sweeps & Arbitrary Waveforms

• mhs5200_configure_sweep: Configure frequency sweep parameters (start/stop frequency, time, mode).
• mhs5200_set_sweep: Start or stop the configured sweep.
• mhs5200_upload_arb_waveform: Upload custom waveform data from a file.

Example Workflow

1. Connect: Call mhs5200_connect with the serial port name (e.g., COM3).
2. Check Status: Call mhs5200_get_status to read the current device settings.
3. Configure: Use mhs5200_set_frequency, mhs5200_set_amplitude, etc. to set the desired output.
4. Enable Output: Call mhs5200_set_output to turn on the signal.
5. Disconnect: Call mhs5200_disconnect when finished.
