Earth & Sky
Live earthquakes, ISS position, weather, moon phase, and stargazing conditions.
Tracks real-time earthquakes from USGS with filtering by magnitude and location. Shows current ISS position, weather forecasts, moon phases, and computes true stargazing visibility by combining dark hours, cloud cover, and moon illumination. No API key required.
Try asking Muse: "Tell me if tonight is good for stargazing at my location and show me any recent earthquakes nearby."

Also use it in ChatGPT or Claude
Earth & Sky 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.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
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
Add it to Claude
- 1
Open Claude settings
In Claude, open Settings, then Connectors.
- 2
Add a custom connector
Choose Add custom connector, give it a name, and paste the link.
