Copilot Studio MCP Connection Issue – Unable to Load Tools (OData Error)

(0) ShareShare
ReportReport
Posted on by 26

Hi everyone,

I am trying to build an agent in Copilot Studio using the Business Central MCP server, but I am unable to connect to the MCP tools. Whenever I try to load or refresh the tools, I receive an OData-related connection error.

What is confusing is that I have successfully created and used MCP-based agents multiple times in the past without any issues. However, this problem has been occurring consistently for the last two weeks.

Things I have already tried:

 

  • Creating a new Copilot Studio agent
  • Creating a new MCP configuration in Business Central
  • Deleting and recreating the MCP connection in Copilot Studio
  • Clearing browser cache and cookies

I also tested creating a tool without MCP using Find Records (V3), and that works perfectly. The agent is able to connect to Business Central and retrieve data without any issues. The problem only seems to occur when using MCP tools.

Despite these steps, I am still unable to retrieve the MCP tools.

Has there been any recent change to how MCP connections are configured or authenticated between Business Central and Copilot Studio? Is anyone else experiencing the same issue?

This is the error
