## What it does

flstudio-mcp gives an MCP client access to FL Studio’s mixer, plugins, piano roll, routing, and project state. It can inspect a mix, suggest and apply reversible changes, read installed plugin data, write notes and chords, build arrangement sections, and export a multi-track MIDI file. It also supports tempo and key detection plus melody transcription from audio. The server exposes 67 tools across 14 categories and 6 live resources covering project, mixer, transport, channels, patterns, and status.

You need FL Studio 2025 or newer, Python 3.10+, an MCP client, and two virtual MIDI ports named `FLStudioMCP RX` and `FLStudioMCP TX`. Windows uses loopMIDI; macOS uses IAC Driver. MP3 analysis requires `ffmpeg` on `PATH`. FL Studio’s API does not load plugins, load audio, or render files, so those actions stay in the DAW interface. Note writing also requires running `MCP_Apply` once from the piano roll during each session. Linux is a hard stop here: it is not supported.

## Requirements
- Needs: Python and uv (commands run via uvx)

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add flstudio-mcp -- uvx fl-studio-mcp
```
uvx runs the command named after the package; if the README names another one, use uvx --from fl-studio-mcp <command>

### Codex

**Platform CLI**
```bash
codex mcp add flstudio-mcp -- uvx fl-studio-mcp
```
uvx runs the command named after the package; if the README names another one, use uvx --from fl-studio-mcp <command>

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "flstudio-mcp": {
            "command": "uvx",
            "args": [
                "fl-studio-mcp"
            ]
        }
    }
}
```
uvx runs the command named after the package; if the README names another one, use uvx --from fl-studio-mcp <command>

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "flstudio-mcp": {
            "type": "stdio",
            "command": "uvx",
            "args": [
                "fl-studio-mcp"
            ]
        }
    }
}
```
uvx runs the command named after the package; if the README names another one, use uvx --from fl-studio-mcp <command>

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add flstudio-mcp uvx fl-studio-mcp
```
uvx runs the command named after the package; if the README names another one, use uvx --from fl-studio-mcp <command>

## When to use it
- inspect a mix for clipping and level imbalance
- build a vocal chain from the installed plugin library
- write an arrangement and export it as MIDI
- estimate an audio file’s tempo, key, and melody

## Example prompts
- Inspect the current FL Studio project and list mix issues with proposed fixes.
- Use the plugins installed in FL Studio to prepare a vocal processing chain, then show each change before applying it.
- Write a multi-track arrangement and export the result as a MIDI file.
