Nightfalls MCP

Put sunset intelligence
in your AI assistant.

Nightfalls exposes its sunset toolset over the Model Context Protocol. Point any MCP client at one endpoint and it can find great sunset spots, pull multi-day forecasts, and explain how sunsets work — with live data, no API key required.
