Claude Desktop doesn't connect with server running on vercel

[troontechnologies]

I have configured and setup the MCP on vercel as per instructions, it shows healthy and running. But I try to configure it through Claude Desktop, it remains disabled and doesn't get recognized. Is there any other way to verify connectivity?

I am not been able to connect either, I have my server running on vercel and it's healthy. The errors I see in the log files are:

If you are developing this MCP server you can add output to stderr (i.e. console.error('...') in JavaScript, print('...', file=sys.stderr) in python) and it will appear in this log.
