# Doris MCP Server 0.6.0 Release Notes
**Release Date:** 3 September 2025
**Release Manager:** FreeOnePlus(Yijia Su)
---
## 🚀 Major Features & Enhancements
### Enterprise-Grade Authentication System
Doris MCP Server 0.6.0 introduces a comprehensive authentication framework
designed for enterprise environments:
- **Multi-Authentication Support**: Complete implementation of Token, JWT,
and OAuth authentication systems
- **Granular Control**: Independent switches for each authentication method
with global default security
- **Token-Bound Database Configuration**: Revolutionary approach allowing
tokens to carry their own database connection parameters
- **Hot Reload Capability**: Runtime configuration updates without service
interruption
- **Immediate Validation**: Database configurations are validated at
connection time, not query time
### Advanced Connection Management
Enhanced connection pooling and session management for improved performance:
- **Session Caching**: Intelligent caching of Doris connections to reduce
overhead and prevent timeout issues
- **Connection Pool Optimization**: Proper connection lifecycle management
with automatic release mechanisms
- **Multi-Worker Architecture**: True horizontal scaling with stateless
design for efficient load distribution
---
## 🔧 Critical System Improvements
### Database Configuration Priority System
**Problem**: Inconsistent handling of database configurations across
different authentication methods
**Solution**: Implemented a clear priority hierarchy:
1. Token-bound database configuration (highest priority)
2. Environment variables (.env configuration)
3. Error state (if neither available)
This ensures enterprise users can have token-specific database access while
maintaining fallback mechanisms.
### Hot Reload Configuration Management
**Problem**: Configuration changes required service restarts, causing
downtime
**Solution**: Implemented file-based hot reloading with:
- Real-time monitoring of tokens.json changes (10-second intervals)
- Automatic token revalidation and pool recreation
- Zero-downtime configuration updates
- Comprehensive error handling and rollback mechanisms
---
## 🛠️ Technical Architecture Enhancements
### Unified Configuration Framework
- **Consolidated Configuration Management**: Refactored configuration
handling through unified `DorisConfig` object
- **Command-Line Priority**: Proper precedence handling (command-line >
environment variables > defaults)
- **Docker Compatibility**: Fixed line ending issues for cross-platform
container deployment
### Enhanced SQL Security Framework
- **Improved Injection Detection**: Enhanced SQL injection pattern
recognition for complex queries
- **Access Control Fixes**: Resolved security vulnerability allowing
read-only mode bypass
- **Comprehensive Validation**: Real-time SQL security validation with
detailed error reporting
### Asynchronous Operation Standardization
- **Mixed Async/Sync Fix**: Converted all synchronous methods to
asynchronous for consistency
- **Thread Safety**: Eliminated exception errors related to mixed method
calls
- **Improved Reliability**: Enhanced process consistency across all
operations

#### **Access & Security Controls**
- **Multi-Layer Access Protection**:
- **IP Restriction**: Access limited to localhost (127.0.0.1) and IPv6
loopback (::1) only
- **Admin Token Authentication**: Requires valid
`TOKEN_MANAGEMENT_ADMIN_TOKEN` for access

`http://localhost:3000/token/management?admin_token=<your_admin_token>`
- **Real-Time Permission Validation**: Every operation validates admin
credentials and IP restrictions
#### **Comprehensive Token Operations**
- **Token Creation**: Full-featured form with database configuration support
- Basic Information: Token ID, description, custom token value, expiration
settings
- **Database Binding**: Complete database configuration (host, port, user,
password, database, FE HTTP port)

with hot-reload support
- **Token Management**: Real-time token operations
- **List & Statistics**: Live token inventory with database binding status
- **Token Revocation**: One-click token deletion with immediate file
updates
- **Cleanup Operations**: Automated expired token removal with audit trails
- **Interactive Dashboard**: Live statistics and responsive UI with
real-time updates
#### **Enterprise Security Features**
- **Zero Network Exposure**: Interface only accessible from server host
machine
- **Admin-Only Operations**: All token operations require
administrator-level authentication
- **Audit Trail**: Complete logging of all token management operations
- **Configuration Validation**: Real-time validation of database
configurations before token creation
- **Automatic Token Persistence**: All operations immediately synchronized
with token storage files
### Security Improvements
- **Access Control Enforcement**: Fixed read-only mode bypass vulnerability
- **SQL Injection Protection**: Enhanced detection patterns for complex
query structures
