# AlertChecker MCP Server

Gives any MCP-compatible AI assistant (ChatGPT, Claude, and others) the ability to create AI-monitored web alerts on your behalf. Then you will be told when something happens instead of having to ask — just say **"Alert me when..."**

## What it does

AlertChecker watches the web for you and emails you when a plain-English statement becomes true. Once you connect this MCP server, any supporting AI assistant can create these alerts directly from natural conversation.

**Example prompts:**
- "Alert me when the iPhone 16 Pro is back in stock at apple.com"
- "Let me know whenever it's going to rain in London tomorrow"
- "Email me when Tesla stock drops below $200"
- "Tell me if there's an earthquake over 4.0 magnitude in California"

## Tools

| Tool | Description |
|---|---|
| `create_alert` | Creates an AlertChecker alert from a yes/no question or natural-language statement. AlertChecker monitors relevant web information and notifies you by email (or optionally push notifications) when the answer becomes yes. |

## Icon
