Configuration

Claude Code (Recommended)

Add the PyPI Query MCP Server to Claude Code using the built-in MCP management:

# Add with local scope (project-specific)
claude mcp add pypi uvx pypi-query-mcp-server -s local

# Add with user scope (available across all projects) 
claude mcp add pypi uvx pypi-query-mcp-server -s user
