Summary Fixes X11/XCB crash when running serena-mcp-server in directories without source files Adds headless environment detection to prevent GUI operations in SSH/WSL/Docker environments Improves error messages to provide clear guidance when no source files are found Problem When running serena-mcp-server --context ide-assistant --project /empty/dir in a headless environment (SSH, WSL, Docker), the application would crash with X11/XCB errors: [xcb] Unknown sequence number while appending request [xcb] You called XInitThreads, this is not your fault [xcb] Aborting, sorry about that. python: ../../src/xcb_io.c:157: append_pending_request: Assertion `\!xcb_xlib_unknown_seq_number' failed. Root Cause Empty directories cause ProjectConfig.autogenerate() to raise a ValueError The exception handler attempts to show a GUI error dialog using tkinter In headless environments, tkinter crashes with X11/XCB errors Solution Headless Detection: Added is_headless_environment() to detect when running without a display Skip GUI in Headless: Modified show_fatal_exception_safe() to skip GUI attempts in headless environments Better Error Messages: Improved the error message for empty projects with clear instructions
