Common questions

Is FL Studio MCP Mac safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

FL Studio MCP Mac

macOS-first MCP bridge for FL Studio. It exposes FL Studio transport, mixer, channel, MIDI export, and Piano Roll note-apply workflows to MCP clients such as Claude Desktop, Claude Code, Cursor, and other MCP-capable tools.

This is an alpha MVP. It is intentionally scoped around FL Studio's documented Python MIDI scripting and Piano Roll scripting APIs. It does not promise full headless FL Studio automation.

Why This Exists

Most FL Studio MCP work today is Windows-oriented. macOS has a cleaner CoreMIDI path for virtual ports, and FL Studio supports Python-based MIDI scripts on macOS. This project turns that into a small local MCP server plus companion FL Studio scripts.

What Works

Live bridge over macOS virtual MIDI ports.
FL Studio status and health checks.
Transport: play, stop, record toggle, rewind, song/pattern mode, metronome toggle.
Tempo changes.
Mixer track reads and explicit track mutations.
Channel Rack reads and explicit channel mutations.
Standard MIDI file generation for import into FL Studio.
Piano Roll queue file plus an included .pyscript to insert persistent notes.

Known Limits

FL Studio's MIDI scripting API is not a complete DAW API.
Loading plugins, loading arbitrary audio files, and rendering/exporting are not implemented here.
Persistent note writing goes through the included Piano Roll script. The MCP server queues notes; you run Scripts > FL Studio MCP Apply in the target Piano Roll.
Live bridge setup requires FL Studio's MIDI settings to map the request/response ports. The MCP server starts a singleton local MIDI daemon so Claude Desktop, Claude Code, and terminal tests share the same CoreMIDI endpoints.

Install

From this repo:

python3 -m pip install .

flstudio-mcp-mac-install

The installer copies:

device_FLStudioMCP.py to ~/Documents/Image-Line/FL Studio/Settings/Hardware/FLStudioMCP/
FL Studio MCP Apply.pyscript to ~/Documents/Image-Line/FL Studio/Settings/Piano roll scripts/

Configure FL Studio on macOS

Start the MCP server once so it starts the local MIDI daemon and creates the virtual CoreMIDI ports:

   flstudio-mcp-mac

You can stop this foreground MCP process after the ports appear. The background daemon keeps the FLStudioMCP Request and FLStudioMCP Response ports available for all MCP clients.

Open FL Studio and go to Options > MIDI Settings.
In the input list, choose FLStudioMCP Request.
Set Controller type to FL Studio MCP Mac.
Set the controller output to FLStudioMCP Response.
Restart the MCP client if needed. If duplicate FLStudioMCP ports appear, quit old MCP server processes and start the v0.1.1+ daemon again.

MCP Client Config

For detailed setup across Claude Desktop, Claude Code, Cursor, Windsurf, PyPI, and the MCP Registry, see docs/publishing.md.

Example Claude Desktop config:

"mcpServers": { "flstudio-mcp-mac": { "command": "flstudio-mcp-mac" } } }

For source installs where the command is not on PATH:

"mcpServers": { "flstudio-mcp-mac": { "command": "python3", "args": ["-m", "flstudio_mcp_mac"] } } }

MIDI Note Workflow

Use fl_create_midi_file when you want a normal .mid file to import.

Use fl_queue_piano_roll_notes when you want to apply notes into the currently open Piano Roll:

Ask the MCP client to queue notes.
In FL Studio, open the target channel's Piano Roll.
Run Scripts > FL Studio MCP Apply.

Note shape:

{ "pitch": 60, "start": 0, "duration": 1, "velocity": 100 }, { "pitch": 64, "start": 1, "duration": 1, "velocity": 96 }, { "pitch": 67, "start": 2, "duration": 2, "velocity": 96 } ]

Times are in beats. MIDI pitch uses the standard 0-127 scale.

Development

python3 -m pip install ".[dev]"

PYTHONPATH=src pytest

Set FLSTUDIO_MCP_BRIDGE=mock to run the MCP server with deterministic in-memory FL Studio responses for protocol tests:

FLSTUDIO_MCP_BRIDGE=mock python3 -m flstudio_mcp_mac

Normal live mode uses a background daemon. For low-level debugging, set FLSTUDIO_MCP_BRIDGE=direct to make one MCP process own the virtual MIDI ports directly.

For live FL Studio validation steps, see docs/testing.md.

Protocol

The bridge sends base64 JSON over MIDI control-change frames on channel 16:

CC 120: frame start
CC 121: one base64 character
CC 122: frame end

The FL script only accepts whitelisted command names and returns one JSON response for each request.

Privacy

This server runs entirely on your machine. It collects no telemetry and stores no data on any remote service. It communicates only with your local FL Studio instance over macOS virtual MIDI ports (CoreMIDI), and writes files only where you ask: generated MIDI files and the Piano Roll queue JSON under your local Music folder. No account, API key, or network connection is required, and nothing you do in FL Studio leaves your computer.
