Pick wcgw if you want zero-setup with no API key, and you need the broadest set of tools.

Pick Context7 MCP Server if you want the official, vendor-maintained server, and you prefer the more popular, battle-tested option.

Add wcgw

Install / run

uvx --python 3.12 wcgw@latest

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "wcgw": {
      "command": "uvx",
      "args": [
        "--python",
        "3.12",
        "wcgw@latest"
