Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Countdown Chain makes a printable countdown calendar to one event: month pages with a big days-to-go number in each box, paper-chain strips to tear off one per day, or tear-off cards, plus an ICS file with reminders at 100, 50, 30, 14, 7, 3 and 1 days to go and on the event day. It can count weekdays only and skip listed dates (school holidays). Pass event_date and event_name; start_date defaults to today in the user's time zone. It does not send notifications or track progress.

generate_countdown_calendar — Generate countdown calendar
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a printable countdown calendar, a paper chain countdown, a "how many days until" calendar to cross off, a vacation or wedding countdown printable, an advent-style countdown to an event, or school days left until summer break. Pass event_date and event_name; start_date defaults to today in the user's time zone. Styles: grid (month pages with a big days-to-go number per box), chain (paper-chain strips, 10 per page) or tear_off (12 cards per page). weekdays_only counts Monday to Friday; skip_dates removes holidays. Returns the days-to-go numbers, the PDF, and an ICS file with all-day reminders at 100, 50, 30, 14, 7, 3 and 1 days to go and on the event day. Up to 400 days. Does not send notifications, set phone timers or count hours and minutes; not for a live countdown timer.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
