NotifyHub — Unified Notification MCP Server
If you're tired of wiring up email, SMS, Slack, Discord, Teams, Telegram, WhatsApp, and two dozen other notification channels separately, this gives Claude a unified send operation across all of them. The MCP tools expose NotifyHub's Java notification library: send to single or multiple recipients, chain fallbacks (email fails, try SMS), schedule messages, attach files, apply templates with i18n, and track delivery status. You get 36 tools covering everything from basic sends to batch operations, A/B testing, rate limiting, and dead letter queue management. Reach for this when you want Claude to orchestrate notifications without writing channel-specific code for each service or dealing with retry logic, circuit breakers, and deduplication yourself.
