Global (~/.claude/settings.json):

{
  "mcpServers": {
    "mumcp": {
      "url": "https://YOUR-SITE.com/wp-json/site-pilot-ai/v1/mcp",
      "headers": {"X-API-Key": "spai_YOUR_KEY"}
    }
  }
}

Per-project (.mcp.json in project root):

{
  "mcpServers": {
    "mumcp": {
      "url": "https://YOUR-SITE.com/wp-json/site-pilot-ai/v1/mcp",
      "headers": {"X-API-Key": "spai_YOUR_KEY"}
    }
  }
}

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
