The guidance to remove a microsoft-learn entry may not match what users actually have in their config: in the linked issue log the user-defined server is named/displayed as “Microsoft Learn”, not microsoft-learn. To make the troubleshooting step actionable, consider wording it as removing any manually added server entry that points to https://learn.microsoft.com/api/mcp (regardless of the configured name), or explicitly mention common names like microsoft-learn / “Microsoft Learn”.

Thank you @JiwaniZakir for contributing your finding to this repo. Could you help confirm if the conflict is due to the name microsoft-learn or the url https://learn.microsoft.com/api/mcp like Copilot suggested here?
