MCP tools · 6 exposed · ~1,704 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
post_biorhythm_compatibility ~263

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. Perfect for dating apps, relationship platforms, team-building tools, and couples coaching applications.

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 same date. Ideal for calendar integrations, push notification systems, alert engines, and wellness scheduling tools.

post_biorhythm_daily ~325

Get a daily biorhythm reading with seeded randomness for consistent "biorhythm of the day" features. Same seed and same date always produce the same reading, perfect for daily push notifications, morning briefings, and wellness app check-ins. Returns energy rating, overall phase, a spotlight on one featured cycle, quick-read values for all three primary cycles, a daily message, and actionable advice. The spotlight cycle is deterministically selected by the seed, creating variety across users while maintaining consistency for each individual.

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. Ideal for wellness apps, productivity planners, scheduling tools, and calendar integrations that need forward-looking biorhythm data.

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.
