About Debug Claude Desktop
Debug Claude Desktop is an MCP server in the Files category: minimal instrumented MCP server over stdio: records raw bytes, parsing, handler timing and write back-pressure for every message. Used to trace a Claude Desktop bug that discards tool calls when you leave the chat — filed as anthropics/claude-code#83908.
