Moon Phase FAQs

Question 1

What kind of moon data does it provide?

Accepted Answer

It provides two key pieces of information: 'moon_age' (the number of days since the last new moon) and 'illumination' (the percentage of the moon's face illuminated, from 0-100%).

Question 2

Can I get moon phases for a specific date in the past or future?

Accepted Answer

Yes, absolutely. You can specify a precise `datetime` in RFC3339 (ISO 8601) format as a parameter when calling the 'moon_phase' method. If no datetime is provided, it defaults to the current time.

Question 3

What is MCP (Model Context Protocol)?

Accepted Answer

MCP (Model Context Protocol) is a standardized way for tools to describe and expose their functionality, enabling automatic discovery and interaction. The Moon Phase server serves as a clear, working example of an MCP-compliant server.

Question 4

What is the Moon Phase server?

Accepted Answer

The Moon Phase server is a simple MCP (Model Context Protocol) server implemented in Go that accurately calculates the moon's age (days since last new moon) and illumination percentage based on a given date and time, or the current time.

Question 5

How do I communicate with the Moon Phase server?

Accepted Answer

The server communicates via standard I/O (stdio) using the JSON-RPC 2.0 format. It supports both MCP tool discovery ('tools/list') and direct method calls ('moon_phase') for requesting data.
