Apache Doris

Doris MCP Server

Doris MCP (Model Context Protocol) Server is a backend service built with Python and FastAPI. It implements the MCP, allowing clients to interact with it through defined "Tools". It's primarily designed to connect to Apache Doris databases, potentially leveraging Large Language Models (LLMs) for tasks like converting natural language queries to SQL (NL2SQL), executing queries, and performing metadata management and analysis.

System Requirements

• Python: 3.12+
• Database: Apache Doris connection details (Host, Port, User, Password, Database)

🚀 Quick Start

Installation from PyPI

# Install the latest version
pip install doris-mcp-server

# Install specific version
pip install doris-mcp-server==0.6.0

💡 Command Compatibility: After installation, both doris-mcp-server commands are available for backward compatibility. You can use either command interchangeably.

Start Streamable HTTP Mode (Web Service)

The primary communication mode offering optimal performance and reliability:

# Full configuration with database connection
doris-mcp-server \
    --transport http \
    --host 0.0.0.0 \
    --port 3000 \
    --db-host 127.0.0.1 \
    --db-port 9030 \
    --db-user root \
    --db-password your_password 

Start Stdio Mode (for Cursor and other MCP clients)

Standard input/output mode for direct integration with MCP clients:

# For direct integration with MCP clients like Cursor
doris-mcp-server --transport stdio

🌐 Token Management Interface (New in v0.6.0)

Access the Web-Based Token Management Dashboard for enterprise-grade token administration:

Secure Access Requirements

• Localhost Access Only: Interface restricted to 127.0.0.1 and ::1 for maximum security
• Admin Authentication: Requires TOKEN_MANAGEMENT_ADMIN_TOKEN for access
• Configuration Prerequisites:

  # Required environment variables
  ENABLE_HTTP_TOKEN_MANAGEMENT=true
  ENABLE_TOKEN_AUTH=true
  TOKEN_MANAGEMENT_ADMIN_TOKEN=your_secure_admin_token
  TOKEN_MANAGEMENT_ALLOWED_IPS=127.0.0.1,::1
  

Interface Access

# Access the token management interface
http://localhost:3000/token/management?admin_token=your_secure_admin_token

Available Operations

• 📊 Token Statistics: Real-time overview of active, expired, and total tokens
• ➕ Create Tokens:
  • Basic information (ID, description, expiration)
  • Database binding (host, port, user, password, database)
  • Custom token values or auto-generated secure tokens
• 📋 Token Management:
  • List all tokens with database binding status
  • One-click token revocation
  • Automated expired token cleanup
• 🔒 Enterprise Security:
  • All operations require admin authentication
  • Real-time IP validation
  • Complete audit logging
  • Automatic persistence to tokens.json

🔐 Security Note: The interface is designed for localhost administration only. It cannot be accessed remotely, ensuring maximum security for token management operations.
