What it does

Biorhythm cycles, forecasts, critical days and compatibility for AI agents, one API key.

Quickstart

# 1 — add it to Claude Code
claude mcp add --scope user --transport http biorhythm-mcp-server-by-roxyapi https://roxyapi.com/mcp/biorhythm --header 'X-API-Key: ${X_API_KEY}'

# 2 — ask your agent for something these tools do
#   post_biorhythm_reading, post_biorhythm_forecast, post_biorhythm_critical_days and 3 more

It needs X_API_KEY (RoxyAPI key from roxyapi.com/account): this sends it in the X-API-Key header from your environment, so export it first — its endpoint answers 401 without it.

Biorhythm MCP Server by RoxyAPI costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation

Where are you running it?

Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

Claude Codedeclared by this listing

This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it. Claude Code reads X_API_KEY (RoxyAPI key from roxyapi.com/account) from your environment each time it connects and sends it in the X-API-Key header — its endpoint answers 401 without it — so the key stays out of its config: export it in your shell profile (macOS, Linux), or run setx X_API_KEY … and open a new terminal (Windows).

claude mcp add --scope user --transport http biorhythm-mcp-server-by-roxyapi https://roxyapi.com/mcp/biorhythm --header 'X-API-Key: ${X_API_KEY}'

Reconnect, or start a new session, and the tools appear in the model’s tool list.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add — but its publisher asks for a key of their own on every call.

What it asks of you

It reaches a system of yours, so it needs your own credential rather than the publisher’s: X-API-Key header — RoxyAPI key from roxyapi.com/account. You set it in your own client’s config, on your machine — this marketplace never holds it.

What it writes

One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

What you approve

6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Calculate a complete biorhythm reading for a given birth date and target date. Returns all 10 cycle values (physical, emotional, intellectual, intuitive, aesthetic, awareness, spiritual, passion, mastery, wisdom), phase detection with 8 distinct states, energy rating (1-10), overall phase assessment, editorial-grade interpretation, actionable advice, and critical day alerts. Perfect for wellness a

Generate a biorhythm forecast for a date range up to 90 days. Returns daily cycle values for physical, emotional, intellectual, and intuitive cycles, daily energy ratings, critical day identification, and a summary with best day, worst day, average energy, and period-level guidance.

Find all critical days (zero crossings) within a date range up to 180 days. Returns each critical day with cycle name, period, direction (ascending or descending), severity (single, double, or triple), and advisory text. Highlights rare double critical days where two primary cycles cross zero simultaneously and extremely rare triple critical days where all three primary cycles cross zero on the sa

Calculate biorhythm compatibility between two people by overlaying their cycle profiles on a target date. Returns per-cycle alignment scores (0-100) for physical, emotional, and intellectual cycles, an overall compatibility score, relationship rating, strengths, challenges, practical advice, and a daily sync snapshot showing the absolute difference in each primary cycle.

Get current phase information for all 10 biorhythm cycles without the full interpretation payload. Returns value, phase name, phase label, day position within cycle, cycle period, days until next critical crossing, and short-term trend for each cycle. Includes a compact summary string.

ATool-list grade · score 96 / 100

Release 1.0.1 · scanned 21 Oct 2026

Graded from the tools this server lists, not from its source code.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

What the scan could actually read

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph

The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.

Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
