Configure custom MCP server

If your custom MCP service is deployed across multiple data centers, ensure consistent service versions and tool configurations in all data centers to prevent compatibility issues that may disrupt agent orchestration or cause functional failures.

1. After creating the MCP server, you will automatically be redirected to its Service Details page.

2. In the section of Service Access Configuration Management > Data Center, click Add Data Center on the right, select a data center as needed, and then click OK.
