How to Connect AI Agents (Claude & Cursor) to Real-World Notifications with a Resilient MCP Server in Python

Description and use

Claude and Cursor agents can now send reliable notifications via Telegram, Discord, WhatsApp, and Slack using an MCP server with offline queuing and exponential backoff.

Problem

AI agents lack a secure, reliable way to notify developers when builds finish, errors occur, or bugs are found.

Outcome

Agents can now send reliable, secure notifications across multiple messaging platforms, with automatic retry and offline queuing.

Workflow

• Implement MCP server loop using JSON‑RPC 2.0 over stdio.
• Add token bucket rate limiter and channel dispatcher.
• Integrate httpx for Telegram and Discord alerts.
• Configure agents via claude_desktop_config.json to launch the MCP server.
• Use WhatsApp Cloud API and SQLite WAL queue for production‑grade reliability.

Evidence

Giving an LLM direct shell execution with raw curl commands is notoriously brittle: Secrets and tokens leak into prompt histories.
