• Helm CLI installed

Build and run the Docker container:

# Clone the repository
git clone https://github.com/modelcontextprotocol/servers.git
cd src/helm

# Build the Docker image
docker build -t mcp-helm .

# Clone the repository
git clone https://github.com/modelcontextprotocol/servers.git
cd src/helm

# Install dependencies
uv venv
source .venv/Scripts/Activate.ps1
uv pip install -e .
