🛑 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:
1. Stray Debug Logs
When third-party libraries dump
console.log() or print() onto STDOUT, Claude’s JSON-RPC parser crashes immediately.2. Pipe Buffer Deadlocks
Operating system pipes buffer memory (4KB on Windows, 64KB on Mac/Linux). Without line-buffering, large tool returns freeze the process.
3. Zombie Child Processes
Reloading Claude leaves orphaned servers running in background memory, locking ports and exhausting CPU resources.
