 ### Date Filtering Format (Bedesten API)
-All Bedesten API tools support consistent date filtering:
+All Bedesten API tools support consistent date filtering with **automatic format conversion**:
-- **Format**: ISO 8601 with Z timezone: `YYYY-MM-DDTHH:MM:SS.000Z`
+- **Accepted Formats**: 
+  - Simple format: `YYYY-MM-DD` (e.g., `2020-01-01`) - **automatically converted**
+  - Full ISO 8601: `YYYY-MM-DDTHH:MM:SS.000Z` (e.g., `2020-01-01T00:00:00.000Z`)
+- **Automatic Conversion**: ✅ **NEW FEATURE** - Simple dates are automatically converted to ISO 8601 format
+  - Start dates: `2020-01-01` → `2020-01-01T00:00:00.000Z`
+  - End dates: `2020-01-01` → `2020-01-01T23:59:59.999Z`
 - **Parameters**: `kararTarihiStart` (start date) and `kararTarihiEnd` (end date)
 - **Usage**: Both parameters are optional, use together for date ranges or single parameter for one-sided filtering
 - **Examples**:
-  - Single date: `kararTarihiStart="2024-06-25T00:00:00.000Z", kararTarihiEnd="2024-06-25T23:59:59.999Z"`
+  - **Simple format**: `kararTarihiStart="2024-06-25", kararTarihiEnd="2024-06-25"` ✅ **Works automatically**
-  - Year range: `kararTarihiStart="2024-01-01T00:00:00.000Z", kararTarihiEnd="2024-12-31T23:59:59.999Z"`
+  - **Year range**: `kararTarihiStart="2024-01-01", kararTarihiEnd="2024-12-31"` ✅ **Auto-converted**
-  - From date: `kararTarihiStart="2024-01-01T00:00:00.000Z"` (no end date)
+  - **Full ISO format**: `kararTarihiStart="2024-01-01T00:00:00.000Z", kararTarihiEnd="2024-12-31T23:59:59.999Z"`
-  - Until date: `kararTarihiEnd="2024-12-31T23:59:59.999Z"` (no start date)
+  - **From date**: `kararTarihiStart="2024-01-01"` (no end date)
+  - **Until date**: `kararTarihiEnd="2024-12-31"` (no start date)

+#### ✅ Automatic Date Format Conversion (Completed - Sep 2, 2025)
+- **Issue**: Bedesten API requires ISO 8601 format with timezone, but users were providing simple dates
+- **Problem**: Queries like `kararTarihiStart="2020-01-01"` returned "No data returned from Bedesten API"
+- **Root Cause**: Simple date format `YYYY-MM-DD` not converted to required `YYYY-MM-DDTHH:MM:SS.000Z` format
+- **Solution Applied**: ✅ **Automatic Date Format Conversion** in `search_bedesten_unified`
+  - **Start dates**: `2020-01-01` → `2020-01-01T00:00:00.000Z` (beginning of day)
+  - **End dates**: `2020-01-01` → `2020-01-01T23:59:59.999Z` (end of day)
+  - **Backwards compatible**: Full ISO 8601 dates still work unchanged
+  - **Smart detection**: Only converts if date doesn't already end with 'Z'
+- **Benefits**: 
+  - ✅ **User-friendly**: Simple date input now works seamlessly
+  - ✅ **Inclusive ranges**: End dates include the entire specified day
+  - ✅ **No breaking changes**: Existing ISO 8601 usage unaffected
+- **Production Status**: Deployed on api.yargimcp.com - **Version 353**
+
+#### ✅ KİK v2 MCP Implementation Testing (Completed - Sep 2, 2025)
+- **Issue**: Test KİK v2 MCP implementation with all three decision types
+- **Request**: "üç karar türü ile de mcpyi test et" (test the MCP with all three decision types)  
+- **Decision Types Tested**:
+  - ✅ **uyusmazlik** (dispute) - 500 decisions found and searchable
+  - ✅ **duzenleyici** (regulatory) - 8 decisions found and searchable  
+  - ✅ **mahkeme** (court) - 318 decisions found and searchable
+- **Total Coverage**: 826 decisions across all three decision types
+- **SSL Issues**: ✅ Resolved with legacy server connect configuration  
+- **API Endpoints**: All three endpoints working correctly
+  - `/api/KurulKararlari/GetKurulKararlari` (uyusmazlik)
+  - `/api/KurulKararlari/GetKurulKararlariDk` (duzenleyici)  
+  - `/api/KurulKararlari/GetKurulKararlariMk` (mahkeme)
+- **Hash Analysis**: Comprehensive testing performed to understand document ID encryption
+  - Tested various hash generation patterns (SHA256, HMAC, composite hashes)
+  - Angular/cryptoService.encrypt() style approaches tested
+  - Hash eşleşmesi bulunamadı - client-side session data veya farklı algoritma kullanılıyor olabilir
+- **Result**: ✅ KİK v2 MCP implementation fully operational for all three decision types
+- **Production Status**: All tests passing, search functionality working, ready for production deployment
+
 ### Key Features
 - **FastMCP Framework**: Modern MCP server implementation
 - **Unified APIs**: Single interface for multiple court systems
