概要

What is Reminder?

Reminder is an MCP server that schedules and triggers reminders delivered via Slack or Telegram. Reminders are executed by an external service (cron-job.org), so they are sent even if the server is not running.

How to use Reminder?

Configure the server in your MCP client with the reminder-mcp package, setting the required environment variables (CRON_JOB_API_KEY, NOTIFICATION_PLATFORM, and either Slack or Telegram credentials). Invoke reminders using natural language instructions through an LLM, for example: "Remind me to call Alice in 5 minutes."

Key features of Reminder

Reminders delivered via Slack or Telegram.
Uses cron-job.org for reliable, server‑independent scheduling.
Natural language creation, listing, and deletion of reminders.
Reminders must be scheduled at least 2 minutes ahead of time.

Use cases of Reminder

Schedule a reminder to call a contact in a few minutes.
Set a reminder for a doctor appointment at a specific time tomorrow.
List all currently active reminders.
Delete a specific reminder by its title.

よくある質問

What happens if my server goes offline?

Reminders are still delivered because they are scheduled and triggered by cron-job.org, which sends the notification directly to Slack or Telegram regardless of your server’s status.

How far in advance must a reminder be set?

Reminders must be set at least 2 minutes ahead of the desired time.

What credentials do I need?

You need a cron-job.org API key, choose a notification platform (`slack` or `telegram`), and then either a Slack webhook URL or a Telegram bot token and chat ID. Detailed instructions are provided in the README.

Can I use both Slack and Telegram simultaneously?

No—you set a single `NOTIFICATION_PLATFORM` environment variable to either `slack` or `telegram`. Only one platform can be active per server instance.
