[MCP] MCP server is disconnecting
I did everything from README and Claude Desktop is returning this
2025-04-21T08:26:10.326Z [cua-agent] [info] Initializing server...

2025-04-21T08:26:10.356Z [cua-agent] [info] Server transport closed unexpectedly, this is likely due to the process exiting early. 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.

I reinstalled the package and have the same issue. README looks the same. What were the extra dependencies?

@tomascupr - step 1 to 4 needs to happen before starting the MCP server: https://github.com/trycua/cua?tab=readme-ov-file#option-2-full-computer-use-agent-capabilities
