Krzysztof kuhy Rudnicki c05dc9c224 Make disarming survive the install scripts, not just systemd 
Masking the units is not enough on its own. install.sh and install_systemd.sh
both COPY unit files into ~/.config/systemd/user, which silently overwrites
systemd's /dev/null mask symlinks and re-arms enforcement -- so a mask alone
loses to anyone running the obvious install command by reflex.

The marker file is the second step: while it exists, no path may install units
or enable timers, and clearing it is an explicit --rearm. --status stays usable
while disarmed but says so loudly, because "armed: no" on its own reads like a
bug rather than a deliberate state.

README.md

screen-locker

Tkinter/systemd screen locker with workout tracking, sick-day management, and wake-alarm integration. It enforces a workout cadence by locking the screen until a RunnerUp-verified (or explicitly justified) workout is logged.

MCP server (Claude Code integration)

screen-locker exposes a read-only MCP server (screen_locker._mcp) so Claude Code and its subagents can query workout compliance and the lock-decision state through typed tools — without shelling out to the screen-locker-status CLI or opening the Tk window.

  • Read-only tools: get_status (full status snapshot), get_summary (one-line i3blocks summary + ok/warn/lock state word), explain_lock (why the screen is / isn't locked right now), get_flags (the individual boolean lock-decision predicates for today).
  • There are no write/action tools, by design. Nothing here logs a workout or mutates state — workouts are logged only from RunnerUp-verified TCX data, never from a caller's claim. No tool exposes the sync token or any HMAC key.

The mcp SDK is an optional dependency (pip install -e '.[mcp]'), kept out of the CLI/systemd system-python path. One-time setup of the dedicated venv that Claude Code spawns:

./scripts/setup_mcp.sh

Registration lives in the checked-in .mcp.json (project scope). Restart Claude Code in this repo and approve the project MCP-server prompt for it to load. Verify with claude mcp list.
