   - Features: Some optimization patterns
   - Status: **Remove (features merged into BestPractice)**

5. **FullArchitectureLegalMCPServer** (205 lines)
   - Location: `src/full-architecture-server.ts`
   - Features: Tool registry integration
   - Status: **Remove (superseded by BestPractice)**

### Current Entry Points

- `src/index.ts` - Uses `BestPracticeLegalMCPServer` ✅
- `src/index-refactored.ts` - Uses `RefactoredLegalMCPServer` ❌
- `src/main-optimized.ts` - Uses `OptimizedLegalMCPServer` ❌
- `src/full-architecture-server.ts` - Standalone ❌
- `src/enterprise-server.ts` - Standalone ❌

## Consolidation Strategy

### Phase 1: Keep the Best ✅
- **Keep**: `src/server/best-practice-server.ts`
- **Keep**: `src/index.ts` (primary entry point)
- Already exports `LegalMCPServer` which extends `BestPracticeLegalMCPServer`

### Phase 2: Remove Redundant Implementations
Files to remove:
1. `src/server/refactored-server.ts`
2. `src/server/optimized-server.ts`
3. `src/index-refactored.ts`
4. `src/main-optimized.ts`
5. `src/full-architecture-server.ts`
6. `src/enterprise-server.ts` (after verifying features are in BestPractice)

### Phase 3: Update package.json
Current bin entries:
```json
{
  "legal-mcp": "dist/index.js",
  "legal-mcp-enterprise": "dist/enterprise-server.js",
  "legal-mcp-refactored": "dist/index-refactored.js",
  "legal-mcp-optimized": "dist/main-optimized.js",
  "legal-mcp-full-architecture": "dist/full-architecture-server.js"
}
```

Should become:
```json
{
  "legal-mcp": "dist/index.js"
}
```

All scripts should use the single entry point.

### Phase 4: Feature Verification

Enterprise features already in BestPractice:
- ✅ MiddlewareFactory (includes auth, sanitization, rate-limiting)
- ✅ Circuit breakers
- ✅ Metrics and monitoring
- ✅ Graceful shutdown
- ✅ Health endpoints
- ✅ Comprehensive error handling

Enterprise features to verify:
- Compression middleware (check if it's in MiddlewareFactory)
- Audit logging (check if it's in MiddlewareFactory)

## Implementation Steps

1. ✅ Verify BestPracticeLegalMCPServer has all needed features
2. Remove redundant server files
3. Update package.json bin and scripts
4. Update README to document single entry point
5. Test that everything still works
6. Update documentation references

## Benefits

- **Reduced Code**: ~1,500 lines of duplicate code removed
- **Simplified Maintenance**: Single server implementation to maintain
- **Clear Entry Point**: Users know which server to use
- **Easier Testing**: Single implementation to test
- **Better Documentation**: Document one implementation well
- **Faster Onboarding**: New developers only need to learn one server

## Migration Guide for Users

If you're using:
- `legal-mcp-enterprise` → Use `legal-mcp` (same features via config)
- `legal-mcp-refactored` → Use `legal-mcp`
- `legal-mcp-optimized` → Use `legal-mcp`
- `legal-mcp-full-architecture` → Use `legal-mcp`

All features are available via environment variable configuration in the single `legal-mcp` command.
