**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](docs/demo/osc-bridge-demo.png)

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**:

npm install -g @roomi-fields/osc-bridge      # downloads the prebuilt binary
# or grab a binary directly from the Releases page
osc-bridge run --device devices/arturia/minilab3.json --out-port 4

MCP client config and the five tools → [`docs/MCP.md`](docs/MCP.md). Full quick-start with MIDI port discovery → [§ Install & quick start](#install--quick-start).

Why a bridge?

Modern synths — hardware and software alike — expose themselves over MIDI, SysEx, and OSC with proprietary, scattered protocols. Using them from live-coding environments, a DAW, a script, or an LLM is painful:
