🛑 Why Claude Desktop & Cursor Silently Freeze
In the Model Context Protocol (MCP), clients communicate with local tools strictly through STDIO pipes using newline-delimited JSON-RPC 2.0. If anything taints that stream, Claude Desktop locks up with endless spinning dots:
console.log() or print() onto STDOUT, Claude’s JSON-RPC parser crashes immediately.
