alert-my-human

A lightweight, multichannel MCP server that lets agents send alerts — useful for notifying a human when a scheduled job fails, data is missing, or something otherwise needs attention.

Supports email, Slack, Telegram, SMS, and generic webhooks. Enabled a channel by setting its env vars. Callers pick which configured channels to deliver to on each call.

Tools

list_channels

Returns which channels are currently configured. No params. Call this before send_alert to know which channel names are valid.

send_alert

Param	Type	Required	Description
channels	array of channel names	Yes	Which channels to deliver to (e.g. ["slack", "email"]). See list_channels.
severity	info | success | warning | error	No (default info)	Controls the color/emoji used in the alert.
title	string	Yes	Short headline for the alert.
message	string	Yes	Body of the alert.
context	object of string key/value pairs	No	Extra details rendered as a list (e.g. job name, error code).

Setup

1. Copy .env.example to .env and fill in:
   • AUTH_API_KEY — any random secret string; callers must send it as Authorization: Bearer <key>.
   • Then configure one or more channels (leave a channel's vars unset to disable it):
     • Email — SENDING_EMAIL, RESEND_API_KEY (from resend.com), ALERT_EMAIL (one address, or several comma-separated).
     • Slack — SLACK_WEBHOOK_URL (an incoming webhook).
     • Telegram — TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID.
     • SMS — TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_FROM_NUMBER, ALERT_PHONE_NUMBER (from twilio.com).
     • Webhook — WEBHOOK_URLS, comma-separated; each receives the alert as JSON.
2. pnpm install
3. pnpm dev

Connecting an MCP client

Register the server with a static bearer token header, for example in Claude Code's mcpServers config:

{
  "type": "http",
  "url": "https://your-deployment.example.com/api/mcp",
  "headers": {
    "Authorization": "Bearer <AUTH_API_KEY>"
  }
}

Testing

Run npx @modelcontextprotocol/inspector@latest http://localhost:3000 undefined, then connect it to http://localhost:3000/api/mcp with an Authorization: Bearer <AUTH_API_KEY> header.

Roadmap

• Landing page with prompt to auto deploy via vercel
• Phone call alerts
