Pingfyr lets you manage scheduled reminders, delivering notifications across multiple channels automatically.
Create Reminders — Schedule a new reminder with a title, body, fire time (ISO 8601), and delivery channel. Supports one-time or recurring schedules (daily, weekly, monthly, or custom cron expressions) with IANA timezone support and optional metadata.
List Reminders — Retrieve all reminders with optional filtering by status (pending, processing, delivered, failed, cancelled) and pagination via limit and offset.
Update Reminders — Modify any pending reminder's title, body, fire time, channel, recipients, repeat schedule, or timezone.
Cancel Reminders — Prevent a pending reminder from being delivered.
Supported delivery channels:
Email — One or more addresses (Starter+ plan required)
Webhook — HTTP POST to any URL
Slack — Via Incoming Webhook URL
Discord — Via Webhook URL
Telegram — Via a bot using bot:<bot_id>:<chat_id> format
OpenClaw — POST to an OpenClaw endpoint
Google Calendar — Create events on a connected account (Starter+ plan required)

Enables the creation of events on a connected Google Calendar as a form of scheduled reminder.
Supports scheduling and delivering reminder notifications to Slack channels via incoming webhooks.

Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Pingfyr Remind me on Slack to check the server status in 2 hours"
That's it! The server will respond to your query, and you can continue using it as needed.
