About Moonlora
Moonlora is a hosted MCP server for people and applications needing lunar data. It calculates phases with the Meeus algorithm and provides moon signs, lunar event dates, and moonrise and moonset times by coordinates.
Key features
- 01Moon phase and illumination
- 02Moon signs and next lunar events
- 03Yearly full moon listings
- 04Yearly new moon listings
- 05Moonrise and moonset by coordinates
Use cases
- 01Check the moon phase for a date
- 02Find full and new moon times for a year
- 03Look up moonrise and moonset for a location
MCP support
Exposes tools for querying moon phases and listing full and new moons to MCP clients through its remote endpoint. It requires no installation or API key.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
