Moku MCP Server

moku-mcp

Model Context Protocol (MCP) server for Moku device control.

Overview

This MCP server provides LLM-friendly tools for controlling Moku devices:

• Device Discovery: Find Moku devices on the network
• Connection Management: Attach/detach with graceful ownership handoff
• Configuration Deployment: Push MokuConfig models to hardware
• Routing Control: Configure MCC signal routing
• Metadata Queries: Get device info and slot status

Architecture

Session Model: Stateful connection management

• attach(device_id) → Connect and maintain ownership
• detach() → Release ownership (allows iPad/CLI handoff)

Graceful Handoff: Supports common workflow where ownership moves between:

• Machine A (CLI) → iPad (GUI) → Machine B (LLM) → ...

MokuConfig-Driven: Uses moku-models package for type-safe configuration.

Installation

# Clone repository
git clone https://github.com/sealablab/moku-mcp.git
cd moku-mcp

# Install with uv (recommended)
uv pip install -e .

# Or with pip
pip install -e .

Usage

Running the MCP Server

# Run server via stdio (MCP standard)
python -m moku_mcp

# Or with uv
uv run python -m moku_mcp

Integration with Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "moku": {
      "command": "uv",
      "args": ["run", "python", "-m", "moku_mcp"],
      "cwd": "/path/to/moku-mcp"
    }
  }
}

Using the Session Context Manager

For safe device management with automatic cleanup:

from moku_mcp.session import MokuSession

async def deploy_config_safely(device_id: str, config: dict):
    async with MokuSession(device_id) as moku:
        # Device is automatically connected
        result = await moku.push_config(config)
        # Device is automatically released even if error occurs
        return result

MCP Tools

1. discover_mokus()

Discover Moku devices on network via zeroconf.

Returns: List of devices with IP, name, serial number

2. attach_moku(device_id)

Connect to Moku device and assume ownership.

Args:

• device_id (str): IP address, device name, or serial number

Returns: Connection status and device metadata

3. release_moku()

Disconnect and release ownership.

Returns: Disconnect status

4. push_config(config)

Deploy MokuConfig to connected device.

Args:

• config (dict): MokuConfig serialized as dictionary

Returns: Deployment status

Example:

config = {
    "platform": {...},
    "slots": {
        1: {
            "instrument": "CloudCompile",
            "bitstream": "path/to/bitstream.tar"
        }
    },
    "routing": [
        {"source": "Slot1OutA", "destination": "Output1"}
    ]
}

5. get_config()

Retrieve current device configuration.

Returns: MokuConfig as dict

6. set_routing(connections)

Configure MCC signal routing.

Args:

• connections (list): List of MokuConnection dicts

Example:

connections = [
    {"source": "Input1", "destination": "Slot1InA"},
    {"source": "Slot1OutA", "destination": "Output1"}
]

7. get_device_info()

Query device metadata.

Returns: Dict with name, serial, IP, platform type

8. list_slots()

List configured instrument slots.

Returns: Dict of slot numbers to instrument info
