🌍 Language Support

Turkish Language (100% Accuracy)

The MCP server provides perfect Turkish-to-English translation:

// Turkish queries automatically translated
"buton" → "button"
"veri tablosu" → "data table"
"tarih seçici" → "date picker"
"form girişi" → "form input"

// Multi-word phrases supported
"tarih picker" → "date-picker"  // Edge case handling (v5.2.1)
"açılır menü" → "dropdown-menu"

Test Coverage: 100% (20/20 Turkish translation tests passing)

🏆 Pro-First Policy

Default Behavior

By default, the MCP server prioritizes Pro components for better user experience:

Query: "table"
→ Returns: Pro/Mixed "table" component (3x score boost)

Query: "data table with sorting"
→ Returns: Pro "data-table" component (highest features)

Free Component Requests

Explicitly request free components:

Query: "free button" | "ücretsiz kart" | "bedava tablo"
→ Returns: Free version (no Pro boost)
