uv vs uvx: Which to Use?

uvx (Recommended for Users)

• Purpose: Run Python packages directly from PyPI
• Use case: End users who just want to use the MCP server
• Command: uvx vnstock-mcp@latest
• Benefits:
  • No local setup required
  • Automatic dependency management
  • Isolated execution environment

uv (Recommended for Developers)

• Purpose: Python project and package management
• Use case: Developers who want to modify/contribute to the code
• Command: uv run python src/vnstock_mcp/server.py
• Benefits:
  • Full source code access
  • Development workflow
  • Ability to make changes

Claude Desktop Integration

To use this MCP server with Claude Desktop, add the following configuration to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

Method 1: Using uvx (if PATH configured)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uvx",
      "args": ["vnstock-mcp"]
    }
  }
}

Method 2: Using uvx (if PATH NOT configured)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "/Users/YOUR_USERNAME/.local/bin/uvx",
      "args": ["vnstock-mcp"]
    }
  }
}

Method 3: Development from source (script path)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/USERNAME/PATH_TO/src/vnstock_mcp",
        "run",
        "server.py"
      ]
    }
  }
}

Method 4: Development from source (Python module)

{
  "mcpServers": {
    "vnstock-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/USERNAME/PATH_TO/vnstock-mcp",
        "run",
        "python",
        "-m",
        "vnstock_mcp.server"
      ]
    }
  }
}

Note:

• Replace YOUR_USERNAME with your actual username in Method 2
• Replace USERNAME and PATH_TO with your actual username and path in Method 3 and 4
• After quitting and restarting Claude Desktop, if it still can't detect the mcp server, check if uvx is in your PATH. If not, add ~/.local/bin to your PATH:

# For zsh (macOS default)
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# For bash
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Publishing to PyPI

For maintainers, use the automated publish script:

# Set UV_PUBLISH_TOKEN in .env file, then run:
python dev/publish.py

Or publish manually:

uv publish --token $UV_PUBLISH_TOKEN
