- One JSON file per device driver; no Rust recompilation needed
- 849 hardware/software devices supported out of the box
- Bridges MIDI/SysEx hardware and OSC software (Ableton, Bitwig, etc.)
- Built-in MCP server exposes the whole catalogue to LLMs
- Bidirectional: incoming MIDI decoded and re‑emitted as OSC
- Rate‑limited, backpressure‑aware, zero‑alloc hot path runtime
- Reconfigurable controllers with Lua scripting escape hatch

Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

Download and install Highlight from highlightai.com/download
Navigate to the plugins tab and select "Add Custom Plugin"
Configure the plugin with the settings below

Plugin Name Declarative OSC bridge for music hardware and software

Command (node, npx, python, etc.)

Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
Enable "Start Automatically" if you want the plugin to start when Highlight launches

Setting up with Cursor

Open Cursor's settings
Navigate to the MCP section
Click "Add new Global MCP server"

From the repository

Run it as an MCP server with npx -y @roomi-fields/osc-bridge mcp, then configure your MCP client (e.g., Claude Desktop) to point to that command. Each supported device is described by one JSON file, so you can control synths and DAWs via named OSC addresses after startup.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.

osc-bridge

Declarative OSC bridge for music hardware and software — and an MCP server to drive it from an LLM.

849 hardware synthesizers over MIDI / SysEx, plus DAWs and live-coding
environments over OSC (Ableton, Bitwig, Reaper, Sonic Pi, SuperCollider, Pure
Data, TouchDesigner, VCV Rack). Every device gets a clean, named OSC surface
described by one JSON file. Drive it from a live-coding client, a DAW, a
script, the CLI — or from Claude via the built-in MCP server (a MIDI MCP
and OSC MCP).

osc-bridge — clients (OSC clients, the CLI, an LLM via MCP) feed one osc-bridge core that fans out to hardware synthesizers over MIDI/SysEx and music software (Ableton, Bitwig, Reaper, Sonic Pi) over OSC

Install

As an MCP server — drive synths and DAWs from Claude, nothing to install:

npx -y @roomi-fields/osc-bridge mcp

As a standalone bridge / CLI:

```bash
npm install -g @roomi-fields/osc-bridge # downloads the prebuilt binary
