Copilot agent - MCP server communication issues

(0) ShareShare
ReportReport
Posted on by

Hi everyone!


Setup:
I have created a Copilot Studio agent that is connected to a remote MCP server with a Power Apps custom connector (as many guides and tutorials described). The MCP server and the custom connector require OAuth authorization, and the agent uses "Authenticate manually with Microsoft Entra ID V2" with client secrets (there was a version where "Authenticate with Microsoft" was the authentication setting and the same results were experienced). In theory, my org's users should be able to access this agent and the connected MCP server's tools.


The issue:

  • For me, the agent only responds (in incognito and on other devices as well) with: "Sorry, something went wrong. Error code: SystemError. Conversation ID: {id}. Time (UTC): {time} PM."
  • For other accounts in my organization who have view access to the custom connector, they cannot create the connection for the custom connector; therefore, they cannot use the agent (or its MCP capabilities).
  • For those who have edit rights on the custom connector, they can use the agent and the MCP server's tools flawlessly.

 

Anyone have ideas about what I set up incorrectly? The main question is regarding the first issue - why I, as the creator/owner, can't use the agent

Update:
I had too many PowerApps connection set up and for some reason that cause the problem. I deleted them all (connection) and created only one and then deleted the agent's tool and added it again.
The remaining question it that why do i have to give edit access to the custom connector to the others to be able to create the connection ?
