Alibaba DMS Multi-Cloud

Download the DMS MCP Server source code to your local machine.

git clone https://github.com/aliyun/alibabacloud-dms-mcp-server.git

Create an Access Key ID and Secret from the Alibaba Cloud RAM console, or generate an STS Token. Grant the IAM user the AliyunDMSFullAccess policy so the server can connect to DMS APIs.

Before querying data, the target database must be registered in DMS. Log in to the DMS Console (dms.aliyun.com), click Add Instance, enter the host, port, username, and password, then submit. Alternatively, use the addInstance MCP tool after the server is running.

Edit your claude_desktop_config.json to register the DMS server. The server runs via uv pointing at the cloned source. Replace the path and credentials with your own values.

{
  "mcpServers": {
    "dms-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/alibabacloud-dms-mcp-server/src/alibabacloud_dms_mcp_server",
        "run",
        "server.py"
      ],
      "env": {
        "ALIBABA_CLOUD_ACCESS_KEY_ID": "your_access_key_id",
        "ALIBABA_CLOUD_ACCESS_KEY_SECRET": "your_access_key_secret"
      }
    }
  }
}

To connect to exactly one database without managing multiple instances, add the CONNECTION_STRING environment variable in the format dbName@host:port. This bypasses instance discovery and targets the specified database directly.

"CONNECTION_STRING": "[email protected]:3306"

After saving the config, restart Claude Desktop. In a new conversation, ask 'What instances are in my DMS?' or 'What tables are in my production database?' to confirm the tools are available.
