yunIO MCP Integration with Microsoft Power Platform

This article shows how to integrate yunIO's MCP server as a Custom Connector with Power Automate / Power Apps.

The Custom Connector can be used as a tool in Microsoft Copilot Studio to create chatbots that enable users to retrieve and interact with SAP data without direct SAP access, transaction code knowledge, or SAP GUI experience.

Prerequisites

• A Microsoft account with access to Microsoft Power Automate or Microsoft Power Apps.
• yunIO services must have meaningful descriptions and be enabled for MCP, see Documentation: MCP Server - Expose Srvices via MCP.
• The MCP endpoint of yunIO is exposed to the internet, see Documentation: MCP Server - Activate MCP.

Setup in Power Automate

To create a Custom Connector in Microsoft Power Automate / Power Apps that connects to the yunIO MCP endpoint:

1. In Power Automate, open the section Custom Connectors.
2. Click + New custom connector > Create from blank.
   
3. Give the connector a name of your choice and click Continue.
4. In the General tab, enter the connection details of your yunIO instance.
5. If you use an on-premises data gateway to expose the MCP endpoint of yunIO, activate the checkbox Connect via on-premises gateway.
6. Click Swagger editor to open the swagger view of the general connector settings.
   

7. Copy the MCP server schema (the path section) of the following template into the swagger editor:

   For more information, see Microsoft Documentation: MCP server schema example.

8. In the Security tab, select the authentication type for the MCP server.
   

   • If Anonymous access is enabled in yunIO, select No authentication. When using the custom connector, no authentication is required.
     
   • If Authenticated access is enabled in yunIO, select Basic authentication. When using the custom connector, provide the credentials of a yunIO user.
   • If Request credentials from callers when running services is enabled in the SAP connection, select Basic authentication. When using the custom connector, provide the credentials of an SAP dialog user.
     
9. Click Create connector.
   

The custom connector for the yunIO MCP server is now ready to use.
