**Date:** December 10, 2024  
**From:** Kiro Testing Agent  
**To:** Claude Development Team  
**Priority:** HIGH - Final push to achieve 100% real data integration

---

## 📊 CURRENT STATUS SUMMARY

**Real Data Integration:** 15/35 tools (42.9%) ✅  
**Real API Calls with Issues:** 9/35 tools (25.7%) ⚠️  
**Mock Data Tools:** 11/35 tools (31.4%) 🎭  

**Goal:** Fix remaining issues to achieve 80%+ real data integration

---

## 🎭 TOOLS STILL USING MOCK DATA (11 Tools)

### **Priority 1: Database User Management (5 tools)**

#### 1. `list_database_users`
**Current Implementation:** Uses `MOCK_DATA["database_users"]`
```python
# Line ~1195 in sap_datasphere_mcp_server.py
users = MOCK_DATA["database_users"].get(space_id, [])
```
**Fix Needed:** Replace with real CLI command execution
```python
# Should execute: datasphere dbusers list --space {space_id}
```

#### 2. `create_database_user`
**Current Implementation:** Creates mock user data with `secrets.token_urlsafe(16)`
```python
# Line ~1230 in sap_datasphere_mcp_server.py
password = secrets.token_urlsafe(16)
full_username = f"{space_id}#{database_user_id}"
```
**Fix Needed:** Execute real CLI command
```python
# Should execute: datasphere dbusers create --space {space_id} --databaseuser {user_id} --file-path {definition.json}
```

#### 3. `reset_database_user_password`
**Current Implementation:** Mock password reset
**Fix Needed:** Execute real CLI command
```python
# Should execute: datasphere dbusers password reset --space {space_id} --databaseuser {user_id}
```

#### 4. `update_database_user`
**Current Implementation:** Mock user updates
**Fix Needed:** Execute real CLI command
```python
# Should execute: datasphere dbusers update --space {space_id} --databaseuser {user_id} --file-path {updated_def.json}
```

#### 5. `delete_database_user`
**Current Implementation:** Mock user deletion
**Fix Needed:** Execute real CLI command
```python
# Should execute: datasphere dbusers delete --space {space_id} --databaseuser {user_id} [--force]
```

### **Priority 2: Table Schema Tool (1 tool)**

#### 6. `get_table_schema`
**Current Issue:** Returns mock schema when no tables found
**Root Cause:** The tenant has views/models but no traditional "tables"
**Fix Needed:** Modify to work with views instead of tables, or use relational metadata API

### **Priority 3: Mixed Real/Mock Tools (5 tools)**

#### 7. `list_analytical_datasets`
**Current Issue:** Falls back to mock data
**Fix Needed:** Investigate why real API call returns 400 Bad Request

#### 8. `query_analytical_data`
**Current Status:** Makes real API calls but may have mock fallbacks
**Fix Needed:** Verify all code paths use real API

#### 9-11. **Other tools with potential mock fallbacks**
**Action Needed:** Code review to identify any remaining mock data usage

---

## ⚠️ API ISSUES THAT NEED FIXING (9 Tools)

### **Issue Type 1: API Syntax/Filter Problems (4 tools)**

#### 1. `search_tables`
**Error:** `400 Bad Request`
**URL:** `/api/v1/datasphere/consumption/catalog/assets?$filter=(assetType+eq+'Table'+or+assetType+eq+'View')+and+(contains(tolower(name),+'division'))`
**Problem:** OData filter syntax not supported by this API version
**Fix Options:**
- Remove complex filters, use simple parameters
- Use different API endpoint
- Implement client-side filtering after getting all assets

#### 2. `get_deployed_objects`
**Error:** `400 Bad Request`
**URL:** `/api/v1/datasphere/consumption/catalog/spaces('SAP_CONTENT')/assets?$filter=exposedForConsumption+eq+true`
**Problem:** `exposedForConsumption` filter not supported
**Fix Options:**
- Remove the filter, get all assets and filter client-side
- Use different property name for filtering
- Check API documentation for supported filters

#### 3. `list_analytical_datasets`
**Error:** `400 Bad Request`
**URL:** `/api/v1/datasphere/consumption/analytical/SAP_CONTENT/SAP_SC_FI_AM_FINTRANSACTIONS?$top=50`
**Problem:** Incorrect URL structure or unsupported parameters
**Fix Options:**
- Use service document endpoint first: `/SAP_SC_FI_AM_FINTRANSACTIONS/`
- Remove `$top` parameter
- Use metadata endpoint instead

#### 4. `get_analytical_metadata`
**Error:** `400 Bad Request`
**URL:** `/api/v1/datasphere/consumption/analytical/SAP_CONTENT/SAP_SC_HR_V_Divisions/$metadata`
**Problem:** Asset doesn't support analytical queries (supportsAnalyticalQueries: false)
**Fix Options:**
- Check `supportsAnalyticalQueries` before calling
- Use relational metadata endpoint instead
- Provide better error handling

### **Issue Type 2: HTML Response Problems (2 tools)**

#### 5. `browse_marketplace`
**Error:** `200, message='Attempt to decode JSON with unexpected mimetype: text/html'`
**URL:** `/api/v1/datasphere/marketplace/packages`
**Problem:** API returns HTML page instead of JSON
**Root Cause:** Endpoint might be for browser UI, not REST API
**Fix Options:**
- Find correct REST API endpoint for marketplace
- Add Accept: application/json header
- Check if endpoint requires different authentication
- Use different API version

#### 6. `get_task_status`
**Error:** `200, message='Attempt to decode JSON with unexpected mimetype: text/html'`
**URL:** `/api/v1/dwc/tasks`
**Problem:** API returns HTML page instead of JSON
**Root Cause:** `/dwc/` might be Data Warehouse Cloud legacy endpoint
**Fix Options:**
- Use `/api/v1/datasphere/` endpoint instead
- Find correct tasks API endpoint
- Add proper Accept headers
- Check API documentation for task management

### **Issue Type 3: Missing Endpoints (2 tools)**

#### 7. `search_catalog`
**Error:** `404 Not Found`
**URL:** `/api/v1/datasphere/consumption/catalog/search`
**Problem:** Search endpoint doesn't exist on this tenant
**Fix Options:**
- Check if search is available on different API version
- Use alternative search approach (list + filter)
- Implement client-side search across catalog assets

#### 8. `search_repository`
**Error:** `404 Not Found`
**URL:** `/api/v1/datasphere/consumption/catalog/search`
**Problem:** Same as search_catalog
**Fix Options:**
- Same as search_catalog
- Use repository-specific endpoints if available

### **Issue Type 4: Endpoint Limitations (1 tool)**

#### 9. `get_consumption_metadata`
**Error:** `404 Not Found`
**URL:** `/api/v1/datasphere/consumption/$metadata`
**Problem:** Endpoint not available on this tenant version
**Current Status:** Already has graceful error handling ✅
**Action:** No fix needed, working as intended

## 🔧 DETAILED FIX RECOMMENDATIONS

### **For Database User Management Tools:**

**Implementation Pattern:**
```python
if DATASPHERE_CONFIG["use_mock_data"]:
    return mock_response
else:
    try:
        # Execute real CLI command
        import subprocess
        result = subprocess.run([
            "datasphere", "dbusers", "list", 
            "--space", space_id
        ], capture_output=True, text=True, check=True)
        
        # Parse CLI output and return real data
        return parse_cli_output(result.stdout)
    except subprocess.CalledProcessError as e:
        return error_response_with_mock_fallback(e)
```

### **For API Syntax Issues:**

**Pattern 1: Remove Complex Filters**
```python
# Instead of:
url = f"/assets?$filter=(assetType eq 'Table') and (contains(name, 'search'))"

# Use:
url = f"/assets?$top=100"
# Then filter client-side
filtered_results = [asset for asset in results if 'search' in asset['name'].lower()]
```

**Pattern 2: Check Asset Capabilities First**
```python
# Before calling analytical metadata:
asset_info = get_asset_details(space_id, asset_id)
if not asset_info.get('supportsAnalyticalQueries', False):
    return error_message("Asset doesn't support analytical queries")
```

### **For HTML Response Issues:**

**Pattern: Add Proper Headers and Error Handling**
```python
headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json'
}

try:
    response = await datasphere_connector.get(url, headers=headers)
    if response.headers.get('content-type', '').startswith('text/html'):
        return error_message("API returned HTML instead of JSON - endpoint may not be available")
    return response.json()
except Exception as e:
    return error_with_alternatives(e)
```

### **For Missing Endpoints:**

**Pattern: Implement Workarounds**
```python
# Instead of direct search endpoint:
def search_catalog_workaround(search_term):
    # Get all assets
    all_assets = list_catalog_assets(top=500)
    
    # Filter client-side
    matching_assets = []
    for asset in all_assets['value']:
        if (search_term.lower() in asset['name'].lower() or 
            search_term.lower() in asset.get('label', '').lower()):
            matching_assets.append(asset)
    
    return {'value': matching_assets, 'search_term': search_term}
```
