AlibabaCloud DMS MCP Server

AI-powered unified data management gateway that supports connection to over 40+ data sources, serving as a multi-cloud universal data MCP Server to address cross-source data secure access in one-stop solution.

Supports full Alibaba Cloud series: RDS, PolarDB, ADB series, Lindorm series, TableStore series, MaxCompute series.
Supports mainstream databases/warehouses: MySQL, MariaDB, PostgreSQL, Oracle, SQLServer, Redis, MongoDB, StarRocks, Clickhouse, SelectDB, DB2, OceanBase, Gauss, BigQuery, etc.

Core Features

Provides AI with a unified data access layer and metadata access layer, solving through standardized interfaces:

Maintenance costs caused by data source fragmentation
Compatibility issues between heterogeneous protocols
Security risks from uncontrolled account permissions and non-auditable operations

Key features via MCP include:

NL2SQL: Execute SQL via natural language to obtain data results
Code Generation: Retrieve schema information through this service to generate DAO code or perform structural analysis
Data Retrieval: Automatically route SQL to accurate data sources for business support
Security: Fine-grained access control and auditability
Data Migration: Configure data migration tasks

Usage Methods

DMS MCP Server currently supports two usage modes.

Mode One: Multi-instance Mode

Supports adding instances to DMS, allowing access to multiple database instances.
Suitable for scenarios where managing and accessing multiple database instances is required.

Scenario Example:

You are a company DBA who needs to manage and access various types of database instances (e.g., MySQL, Oracle, PostgreSQL) in production, test, and development environments. With DMS MCP Server, you can achieve unified access and centralized management of these heterogeneous databases.

Typical Question Examples:

Get a list of all databases named test.
Retrieve details of the test_db database from the myHost:myPort instance.
What tables are in the test_db database?
Use a tool to query data from the test_db database and answer: "What is today's user traffic?"

Mode Two: Single Database Mode

Directly specify the target database by configuring the CONNECTION_STRING parameter in the server (format: dbName@host:port).
Suitable for scenarios that focus on accessing a single database.

Scenario Example:

You are a developer who frequently accesses a fixed database (e.g., [email protected]:3306) for development and testing. Set the CONNECTION_STRING parameter in the DMS MCP Server configuration as follows:

CONNECTION_STRING = [email protected]:3306

Afterward, every time the service starts, the DMS MCP Server will directly access this specified database without needing to switch instances.

Typical Question Examples:

What tables do I have?
Show the field structure of the test_table table.
Retrieve the first 20 rows from the test_table table.
Use a tool to answer: "What is today's user traffic?"

Prerequisites

uv is installed
Python 3.10+ is installed
An AK/SK or STS Token with access rights to Alibaba Cloud DMS(AliyunDMSFullAccess)

Pre-configuration

Before accessing a database instance via DMS, you must first add the instance to DMS.

There are two methods to add an instance:

Method One: Use the addInstance tool provided by DMS MCP to add an instance
The DMS MCP Server provides the addInstance tool for quickly adding an instance to DMS.
For more details, see the description of the addInstance tool in the "Tool List."

Method Two: Add an instance via the DMS console

Log in to the DMS Console.
On the home page of the console, click the Add Instance icon in the database instance area on the left.
On the Add Instance page, enter the instance information (e.g., instance address, port, username, password).
Click Submit to complete the instance addition.
