What the publisher says

From the Sonicake Pocket Master repository's README, as published. We do not edit it. Read it on GitHub

pocket-master-mcp

<!-- mcp-name: io.github.voronkovd/pocket-master-mcp -->

An MCP server that lets an AI assistant (Claude Desktop or any other MCP client) control a Sonicake Pocket Master guitar processor over USB MIDI. It also includes offline tools that translate the device's UI into other languages, with Russian built in.

Describe the sound you want in plain words ("tight modern metal rhythm", "clean with a wide chorus, less reverb"). The assistant picks models, sets parameters, reorders the chain, and saves and names presets on the unit.

Unofficial project. It is not affiliated with or endorsed by Sonicake. The protocol is based on the reverse-engineering work in PocketEdit. Reading (current preset, preset names, the full edit buffer) is verified on a real unit with firmware V1.3.3. Writing presets has seen little hardware testing so far, so run backuppresets first**. Patched firmware is unofficial too: you use it at your own risk.

What it can do

  • Live editing: select a model in any block (22 amps + 5 captured-amp profiles, 20 cabs/IRs, 8 drives, FX1/FX2 with 15–17 effects each, 9 delays, 10 reverbs, 3 EQs, noise gate), switch blocks on and off, and set parameters by name with range checking (Gain, Time in ms, Rate in Hz, Mode = Bass, +3dB = on, …).
  • Signal chain: reorder NR / FX1 / FX2 / DLY / RVB around the fixed DRV-AMP-IR-EQ block.
  • Read state: decode the edit buffer (models, on/off, parameter values, chain, preset volume) and list the 100 preset names.
  • Presets: select presets, save the edit buffer to a user slot P01–P50 with a name, rename presets, back up and restore presets.
  • Tone files: apply a whole tone from a JSON file. Examples are in examples/presets.
  • Globals: global volume, input / FX rec / monitor / BT rec levels.
  • UI language: build a firmware file with a translated UI (Russian built in, see UI language).

Requirements

  • A Sonicake Pocket Master connected over USB. It shows up as a class-compliant MIDI port.
  • Python 3.10+.
  • An MCP client, for example Claude Desktop.

The server has to run on the computer the Pocket Master is plugged into, because it needs direct access to the USB MIDI port.

Installation

The easiest way is uv: uvx downloads and runs the server.

Claude Desktop

Open Settings → Developer → Edit Config and add:

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

Restart Claude Desktop completely. If Claude cannot find uvx, use its absolute path (which uvx, typically ~/.local/bin/uvx). For firmware previews (PNG), use "args": ["--from", "pocket-master-mcp[preview]", "pocket-master-mcp"].

Alternatively, run pipx install pocket-master-mcp or pip install "pocket-master-mcp[preview]" and use "command": "pocket-master-mcp".

From source

git clone https://github.com/voronkovd/pocket-master-mcp.git
cd pocket-master-mcp
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"

Then use "command": "/absolute/path/to/pocket-master-mcp/.venv/bin/pocket-master-mcp".

Configuration
