Key features

  1. 01Moon phase and illumination
  2. 02Moon signs and next lunar events
  3. 03Yearly full moon listings
  4. 04Yearly new moon listings
  5. 05Moonrise and moonset by coordinates

Use cases

  1. 01Check the moon phase for a date
  2. 02Find full and new moon times for a year
  3. 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.

Tools

ToolWhat it does
get_moon_phasePhase, illumination, moon sign, next full/new moon for any date. Optional latitude/longitude adds moonrise/moonset (UTC).
list_full_moonsEvery full moon of a year with exact UTC times, traditional names and moon signs.
list_new_moonsEvery new moon of a year with exact UTC times and moon signs.

Example

curl -X POST https://moonlora.com/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_moon_phase","arguments":{"date":"2026-08-28"}}}'

There's also a plain JSON REST API and an embeddable widget — see moonlora.com/developers (OpenAPI 3.1).

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.
