+# 7. Token Management Security Configuration Guide (NEW in v0.6.0) - CRITICAL!
+#    
+#    ⚠️ SECURITY WARNING: Token management endpoints are POWERFUL and DANGEROUS
+#    They allow creation, revocation, and management of authentication tokens.
+#    Improper configuration can lead to complete system compromise.
+#    
+#    🔒 SECURE BY DEFAULT:
+#    - ENABLE_HTTP_TOKEN_MANAGEMENT=false (disabled by default)
+#    - REQUIRE_ADMIN_AUTH=true (admin auth required by default)  
+#    - TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1 (localhost only by default)
+#    
+#    🛡️ SECURITY LAYERS (Applied in order):
+#    1. Configuration Check: HTTP token management must be explicitly enabled
+#    2. IP Restrictions: Only allowed IP addresses/networks can access endpoints
+#    3. Admin Authentication: Valid admin token required for all operations
+#    
+#    📋 CONFIGURATION OPTIONS:
+#    
+#    Disable Token Management (RECOMMENDED for most deployments):
+#    ENABLE_HTTP_TOKEN_MANAGEMENT=false
+#    # All token management endpoints will return 403 Forbidden
+#    
+#    Enable with Maximum Security (Production):
+#    ENABLE_HTTP_TOKEN_MANAGEMENT=true
+#    TOKEN_MANAGEMENT_ADMIN_TOKEN=<secure-random-token-256-bit>
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1
+#    REQUIRE_ADMIN_AUTH=true
+#    
+#    Enable for Private Network (Advanced):
+#    ENABLE_HTTP_TOKEN_MANAGEMENT=true
+#    TOKEN_MANAGEMENT_ADMIN_TOKEN=<secure-random-token-256-bit>
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,192.168.1.0/24,10.0.0.0/8
+#    REQUIRE_ADMIN_AUTH=true
+#    
+#    🔑 ADMIN TOKEN GENERATION:
+#    # Generate secure admin token (Linux/macOS):
+#    openssl rand -hex 32
+#    
+#    # Generate secure admin token (Python):
+#    python -c "import secrets; print(secrets.token_urlsafe(32))"
+#    
+#    🌐 IP CONFIGURATION EXAMPLES:
+#    # Localhost only (most secure):
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1
+#    
+#    # Private network + localhost:
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1,192.168.1.0/24,10.0.0.0/8
+#    
+#    # Specific servers only:
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,192.168.1.10,192.168.1.11
+#    
+#    # Corporate network (be careful):
+#    TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,172.16.0.0/12,192.168.0.0/16
+#    
+#    🚫 NEVER DO THIS (Security Anti-Patterns):
+#    # NEVER allow all IPs:
+#    # TOKEN_MANAGEMENT_ALLOWED_IPS=0.0.0.0/0  # DANGEROUS!
+#    
+#    # NEVER disable admin auth in production:
+#    # REQUIRE_ADMIN_AUTH=false  # DANGEROUS!
+#    
+#    # NEVER use weak admin tokens:
+#    # TOKEN_MANAGEMENT_ADMIN_TOKEN=admin  # DANGEROUS!
+#    # TOKEN_MANAGEMENT_ADMIN_TOKEN=123456  # DANGEROUS!
+#    
+#    📊 ENDPOINT SECURITY TESTING:
+#    # Test security (should fail):
+#    curl -X POST http://external-ip:3000/token/create
+#    # Expected: 403 Forbidden (IP not allowed)
+#    
+#    # Test without auth (should fail):
+#    curl -X POST http://127.0.0.1:3000/token/create
+#    # Expected: 401 Unauthorized (missing admin token)
+#    
+#    # Test with valid auth (should succeed if enabled):
+#    curl -H "Authorization: Bearer your-admin-token" http://127.0.0.1:3000/token/stats
+#    # Expected: 200 OK with token statistics
+#    
+#    🔍 MONITORING & AUDITING:
+#    # All token management access attempts are logged:
+#    tail -f logs/doris_mcp_server_audit.log | grep "token management"
+#    
+#    # Monitor security events:
+#    tail -f logs/doris_mcp_server_info.log | grep -E "(access denied|token management)"
+#    
+#    ✅ SECURITY BEST PRACTICES:
+#    - Keep ENABLE_HTTP_TOKEN_MANAGEMENT=false unless absolutely necessary
+#    - Use file-based token management (tokens.json) instead of HTTP endpoints
+#    - Generate strong admin tokens using cryptographically secure methods
+#    - Restrict access to localhost (127.0.0.1,::1) whenever possible
+#    - Never expose token management endpoints to public internet
+#    - Regularly audit token management access logs
+#    - Use firewall rules as additional protection layer
+#    - Consider VPN access for remote token management needs

+### Q: How to use the new Token-Bound Database Configuration? (New in v0.6.0)
+
+**A:** The revolutionary token-bound database configuration allows each token to carry its own database connection parameters for secure multi-tenant access:
+
+1. **Enable Token Authentication**:
+   ```bash
+   # In your .env file
+   ENABLE_TOKEN_AUTH=true
+   TOKEN_HOT_RELOAD=true
+   TOKEN_FILE_PATH=tokens.json
+   ```
+
+2. **Create tokens.json Configuration**:
+   ```json
+   {
+     "version": "1.0",
+     "tokens": [
+       {
+         "token_id": "tenant-alpha",
+         "token": "tenant_alpha_secure_token_123",
+         "description": "Tenant Alpha database access",
+         "expires_hours": null,
+         "is_active": true,
+         "database_config": {
+           "host": "tenant-alpha-db.company.com",
+           "port": 9030,
+           "user": "alpha_user",
+           "password": "secure_password",
+           "database": "alpha_analytics",
+           "charset": "UTF8"
+         }
+       }
+     ]
+   }
+   ```
+
+3. **Configuration Priority** (New in v0.6.0):
+   - **Token-bound DB config** (highest priority)
+   - **Environment variables (.env)**
+   - **Error if neither available**
+
+4. **Hot Reload Benefits**:
+   - Add new tenants without service restart
+   - Update database credentials in real-time
+   - Automatic validation and rollback on errors
+   - Complete audit trail of changes
+
+5. **Multi-Tenant Usage**:
+   ```bash
+   # Different tokens access different databases automatically
+   curl -H "Authorization: Bearer tenant_alpha_secure_token_123" http://localhost:3000/mcp
+   curl -H "Authorization: Bearer tenant_beta_secure_token_456" http://localhost:3000/mcp
+   ```
+
+### Q: How does Hot Reload work and is it safe? (New in v0.6.0)
+
+**A:** The hot reload system is designed for enterprise production environments with comprehensive safety measures:
+
+**How It Works:**
+- **File Monitoring**: Checks tokens.json every 10 seconds for modifications
+- **Immediate Validation**: New tokens are validated including database connectivity
+- **Atomic Updates**: All-or-nothing configuration updates
+- **Rollback Protection**: Automatic rollback if any token validation fails
+
+**Safety Features:**
+- **Backup and Restore**: Current configuration backed up before changes
+- **Connection Testing**: Database connections tested before applying changes
+- **Error Isolation**: Invalid tokens don't affect existing valid tokens
+- **Audit Logging**: Complete trail of all configuration changes
+
+**Best Practices:**
+```bash
+# Monitor hot reload activity
+tail -f logs/doris_mcp_server_info.log | grep "hot reload"
+
+# Test configuration before applying
+cp tokens.json tokens.json.backup
+# Make changes to tokens.json
+# System will automatically validate and apply or rollback
+```
+
+### Q: How to manage Token lifecycle and security? (New in v0.6.0)
+
+**A:** Token management uses a secure, file-based approach with optional administrative endpoints that have comprehensive security controls.
+
+**Primary Token Management Method (Recommended):**
+```bash
+# 1. Edit tokens.json file directly (safest method)
+nano tokens.json
+
+# 2. Hot reload will automatically detect changes
+# No server restart required - changes applied within 10 seconds
+
+# 3. Monitor hot reload in logs
+tail -f logs/doris_mcp_server_info.log | grep "hot reload"
+```
+
+**Administrative Endpoints (Secure, Local Access Only):**
+
+🛡️ **SECURITY**: These endpoints are protected by comprehensive security controls and are **disabled by default**.
+
+```bash
+# Security Requirements (ALL must be met):
+# ✓ HTTP token management explicitly enabled in configuration
+# ✓ Access only from localhost (127.0.0.1/::1) - IP restrictions enforced
+# ✓ Valid admin authentication token required
+# ✓ Admin authentication enabled in configuration
+
+# Enable HTTP token management (disabled by default)
+export ENABLE_HTTP_TOKEN_MANAGEMENT=true
+export TOKEN_MANAGEMENT_ADMIN_TOKEN=your_secure_admin_token
+export REQUIRE_ADMIN_AUTH=true
+export TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1
+
+# Access with proper authentication
+curl -H "Authorization: Bearer your_secure_admin_token" http://127.0.0.1:3000/token/stats
+
+# Demo page (local access only, with authentication)
+# Access: http://127.0.0.1:3000/token/demo
+```
+
+**Recommended Token Management Workflow:**
+
+1. **Development/Testing**:
+   ```json
+   // tokens.json
+   {
+     "version": "1.0",
+     "tokens": [
+       {
+         "token_id": "dev-token",
+         "token": "dev_secure_token_123",
+         "description": "Development environment access",
+         "expires_hours": 24,
+         "is_active": true
+       }
+     ]
+   }
+   ```
+
+2. **Production Deployment**:
+   ```bash
+   # Use secure token generation
+   openssl rand -hex 32  # Generate secure token
+   
+   # Store in secure configuration management
+   # Never commit tokens to version control
+   # Use environment variables for sensitive tokens
+   ```
+
+**Security Features:**
+- **File-Based Management**: Primary management through secured configuration files
+- **Hot Reload**: Automatic configuration updates without service interruption
+- **Token Hashing**: Tokens stored as SHA-256 hashes internally
+- **Audit Trail**: Complete logging of all token operations and changes
+- **Expiration Management**: Automatic cleanup of expired tokens
+- **Local Admin Only**: Management endpoints restricted to localhost access
+- **Configuration Validation**: Immediate validation of token and database configurations
+
+**Security Best Practices:**
+- Always manage tokens through secure configuration files
+- Never expose token management endpoints to external networks
+- Use strong, randomly generated tokens for production
+- Implement proper file permissions for tokens.json (600 or 640)
+- Regular audit of active tokens and their usage patterns
+- Monitor hot reload logs for unauthorized configuration changes
