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"
