mcp-biorhythm
by molpass
This server calculates and visualizes biorhythm cycles based on a person's birth date, using the get_biorhythm tool.
Biorhythm values: Returns physical (23-day), emotional (28-day), and intellectual (33-day) cycle percentages (−100% to +100%) for a target date (defaults to today in UTC), along with rising/falling trend indicators for each cycle.
Critical days: Identifies days within the date range where a cycle crosses zero, indicating periods of instability or transition.
Sine-wave chart: Generates a 1080×620 PNG image showing all three biorhythm curves over the specified date range.
Flexible inputs: Accepts a birth date (required), an optional target date, and an optional day range around the target date for the chart (1–90 days, default 15).
Timezone-safe: All calculations use UTC midnight to ensure consistent, error-free results across time zones.
Provides biorhythm calculations and sine-wave charts as a tool for the Hermes Agent framework.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-biorhythmMy biorhythm from 1990-05-15"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-biorhythm
생년월일을 받아 바이오리듬 수치 + 사인파 차트(PNG) 를 반환하는 MCP 서버. "내 바이오리듬 보여줘"라고 하면 신체·감성·지성 세 곡선 그래프 이미지를 돌려준다.
구조·네이밍·PNG·설치 규약은
STANDARD.md를 따른다.mcp-qrskeleton 복제본.
계산 (결정론적)
고전 3주기 · 값 = sin(2π × d / period) (d = 출생일로부터 경과 일수):
사이클 | 주기 |
신체 (Physical) | 23일 |
감성 (Emotional) | 28일 |
지성 (Intellectual) | 33일 |
출력은 백분율(−100% ~ +100%).
임계일(critical day): 곡선이 0을 교차(부호가 바뀌는)하는 불안정일. 구간 내 목록으로 표시.
날짜는 UTC 자정 기준으로 계산 → 타임존에 따른 ±1일 오차 없음.
