FL Studio MCP server

This MCP server enables Claude to interact directly with FL Studio, allowing you to create music using AI by sending melodies, chords, drums, and more from Claude to your DAW. It works by establishing a connection through virtual MIDI ports.

Installation Guide

Step 1: Download Required Files

You'll need two main components:

• A folder called "Test Controller"
• A Python file called "trigger.py"

Place the "Test Controller" folder in:

Image-Line/FL Studio/Settings/Hardware

Important: Don't rename this folder or any files inside it.

Step 2: Configure MCP for Claude

1. Follow the MCP quickstart guide to set up MCP servers in Claude
2. When editing the claude_desktop_config files, replace any mentions of "weather.py" with "trigger.py"
3. If the Hammer icon doesn't appear, close Claude via Task Manager and restart it

Your config file should look similar to this:

Step 3: Set Up Virtual MIDI Ports

For Windows:

1. Download and install LoopMIDI
2. Open LoopMIDI and add a port using the + button

For Mac: MIDI ports are automatically set up to receive data.

Step 4: Install Required Packages

1. Navigate to the folder containing trigger.py (the MCP Server file)
2. Activate your conda environment (as shown in the Claude MCP Setup Tutorial)
3. Run the following command to install necessary packages:

uv pip install httpx mido python-rtmidi typing fastmcp FL-Studio-API-Stubs

Step 5: Configure FL Studio

1. Open FL Studio
2. Go to Options > MIDI Settings
3. In the Input Tab, select the MIDI Input you created with LoopMIDI
4. Change the controller type from "generic controller" to "Test Controller"

Step 6: Connect MCP to MIDI Port

1. Ask Claude to get available MIDI ports
2. Copy the port name and number that you created (e.g., "loopMIDI Port 2")
3. Open trigger.py in a text editor
4. Replace the default port with the name of your port:

output_port = mido.open_output('loopMIDI Port 2')  # Replace with your port name

Using the MCP Server

Creating Music with Claude

1. Make sure FL Studio is open and the MCP connection is active
2. Tell Claude to send melodies, chords, or drums using the MCP
3. Click on the instrument you want to record to in FL Studio
4. Claude will live-record to the piano roll of that instrument

Suggested Prompt Format

When starting a new chat with Claude, you can use this format for notes:

Here is format for notes: note(0-127),velocity(0-100),length in beats(decimal),position in beats(decimal)

This helps Claude understand how to structure musical information properly.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
