Basal Body Temperature Tracker

Basal Body Temperature Tracker MCP Connector for Claude

A+

Analyze menstrual cycle phases and ovulation using BBT data.

4 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides specialized tools for fertility awareness by analyzing basal body temperature (BBT) fluctuations. It connects AI agents to your temperature data to identify thermal shifts, determine if you are in the follicular or luteal phase, and pinpoint ovulation events. Use analyze_cycle_phase to check your current cycle stage, detect_ovulation_event to find your ovulation day, estimate_fertile_window to predict fertile days, and calculate_cycle_metrics for a full summary of your cycle length and phase durations.

4 tools expose this connector's capabilities to your AI agent.

analyze_cycle_phase

Determines the current phase of the user's menstrual cycle based on recent temperature data

calculate_cycle_metrics

Provides high-level summaries of cycle length and phase duration

detect_ovulation_event

Pinpoints the specific day ovulation likely occurred

estimate_fertile_window

Predicts the days when the user is most likely to be fertile

Based on these readings: [{'temperature': 36.2, 'cycle_day': 1}, {'temperature': 36.1, 'cycle_day': 2}, {'temperature': 36.5, 'cycle_day': 3}], what phase am I in?

You are currently in the follicular phase.

When was my ovulation based on these readings: [{'temperature': 36.2, 'cycle_day': 1}, {'temperature': 36.2, 'cycle_day': 2}, {'temperature': 36.6, 'cycle_day': 3}, {'temperature': 36.7, 'cycle_day': 4}, {'temperature': 36.7, 'cycle_day': 5}]?

Ovulation likely occurred on cycle day 2.

Can you estimate my fertile window using these readings: [{'temperature': 36.1, 'cycle_day': 1}, {'temperature': 36.1, 'cycle_day': 2}, {'temperature': 36.5, 'cycle_day': 3}]?

Your fertile window is estimated to be between cycle day 1 and cycle day 3.

Provide your BBT readings as an array of temperature and cycle day objects. The tools will then process this data to provide insights like ovulation detection or phase analysis.
