Connects Claude to Pingfyr's reminder API with four tools: create_reminder, list_reminders, update_reminder, and cancel_reminder. Supports seven delivery channels including email, webhook, Slack, Discord, Telegram, Google Calendar, and OpenClaw. Built for scheduling agent wake-ups via webhook or notifying humans when something needs attention later. Handles recurring reminders with cron expressions and timezone support. Reach for this when your agent needs to schedule follow-ups, send delayed notifications to team channels, or trigger itself to check back on long-running processes. The webhook channel is the standout for agent-to-agent coordination without standing up infrastructure.
