Anecast
US weather forecasts with alerts, what changed overnight, forecaster reasoning, and historical context.
Provides National Weather Service forecasts for any US location with active watches and warnings, shows what changed since yesterday, explains the forecaster's reasoning, and compares conditions to historical records for that date.
Try asking Muse: "What's the weather forecast for my trip to New Orleans this weekend, and how unusual will it be compared to normal?"

Anecast is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

Create the connector

Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
