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."

FAQ from Reminder
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.
