Tried to install the retellai mcp server. It was not working. After a debugging session wit opus 4.5 it gave me the following.
"""Great, now I've found the problem! Look at this line that keeps repeating in the log:
Message from server: {"jsonrpc":"2.0","id":1,"error":{"code":-32603,"message":"Unable to read unfine properties (reading '_zod')"}}
This is a bug in the @abhaybabbar/retellai-mcp-server package itself, not in your configuration. The server starts correctly, but when Claude requests the tools list (tools/list), the package crashes with an internal error related to Zod (a validation library).
This is a version incompatibility issue between the package's dependencies. It's not something you can fix on your end without modifying the package's code"""
Is there anything to do?
I am not a developer, so I apologize upfront if I made some stupid mistake.
Thank you
