Overview

AI-generated overview

A remote Korean Saju (Four Pillars) calculator that lets an assistant compute birth charts, day pillars, luck flow, and monthly fortune.

What it does
Yunseul is a remote MCP endpoint for Korean Saju (Four Pillars) astrology. According to its registry description, it calculates a birth chart, the day pillar, luck flow, and monthly fortune. The manifest lists no individual tools, but notes that calculation tools require an API key while a price-listing tool is free.
When to use it
Use it when an assistant needs Korean Four Pillars readings — natal charts, day pillars, luck cycles, or monthly fortune — without implementing the calendar and astrology logic locally. It is not a general-purpose calendar or date tool.
Requirements
A remote MCP connection to the provider's endpoint over streamable HTTP. Calculation tools need an API key sent in the Authorization header as a Bearer token; the key is obtained from the provider's site. The price-listing tool is described as free. No local runtime or packages are declared.
Before you install
The Authorization header carries a secret API key, so it should be stored and transmitted carefully. The manifest declares no authentication beyond that key, and no tool list is published, so verify what each tool does before use. Calculation requests send birth data to a third-party service.
