Installation

Using uv (Recommended)

1. Install uv if you haven't already:

pip install uv

2. Create and activate a virtual environment:

# Create virtual environment
uv venv

# Activate virtual environment
# On Unix/macOS:
source .venv/bin/activate
# On Windows(cmd):
call .venv\Scripts\activate.bat

3. Install the package:

uv pip install .

Running the Server

You can run the server using uv directly:

uv --directory <project_path> run -m src.run_mcp_server

For example, on Windows:

uv --directory C:\path\to\guitar_pro_mcp2 run -m src.run_mcp_server

Or using the Python module directly after installation:

python -m src.run_mcp_server

Using pip

pip install guitar-pro-mcp

From source

1. Clone the repository:

git clone https://github.com/yourusername/guitar-pro-mcp.git
cd guitar-pro-mcp

2. Install the package:

# Install in development mode with all dependencies
pip install -e ".[dev]"

# Or install without development dependencies
pip install -e .

2. Connect to the server using an MCP client.

Usage(Direct)
