## Capabilities

### Determine current fasting/feeding status
Instantly checks if the user is currently within their scheduled eating window or deep in a fast.

### View complete daily schedule boundaries
Retrieves all four critical timestamps for the day, including transitions that cross midnight.

### Calculate time until next meal event
Provides a precise countdown of how much time is left before any specified target meal or window begins.

## Use Cases

### Trying to follow a complex 16/8 schedule
A user asks their agent, 'Am I good to eat now?' The agent calls `get_current_state_details` and replies: 'You are currently in your feeding window. You've got about three hours left.' This eliminates the guesswork when tracking complex protocols.

### Planning for a travel day with time zone shifts
A coach asks their agent to map out boundaries for an 8-hour eating window starting at noon local time. The tool uses `get_window_boundaries` and correctly shows the full schedule, even accounting for midnight transitions in different time zones.

### Needing a quick reminder before a workout
A user needs to know when their pre-workout meal window closes. They ask how long they have until 4:00 PM, and the agent uses `calculate_duration_until_event` to give them an accurate countdown.

### Checking a full week's schedule at once
The user asks for all scheduled boundaries. The MCP runs through multiple days using `get_window_boundaries`, providing the necessary data points for meal prep and planning.

## Benefits

- Stop guessing about your diet. Using `get_current_state_details` immediately tells you if you're in a feeding or fasting window, so you never risk breaking your fast accidentally.
- Manage complex schedules that cross midnight. The tool uses `get_window_boundaries` to map out every boundary for the day, giving you total clarity on your eating limits.
- Optimize meal timing with precision. `calculate_duration_until_event` gives you a clear countdown, so you know exactly how much time is left until that pre-workout shake or evening snack.
- Saves you from manual calculation. Instead of using multiple spreadsheets to track boundaries and transitions, your agent handles it all in one step.
- Reduces cognitive load. You get definitive answers on status and timing instantly, freeing up mental energy for actually following your routine.

## How It Works

The bottom line is that you stop guessing about your schedule and start acting based on real-time data.

1. You first define your fasting parameters, such as the start and length of your feeding window.
2. Your AI client runs a query against this MCP to analyze your current time relative to those boundaries.
3. It returns an actionable status—for example, 'You are currently in a fast' or 'Dinner starts in 45 minutes.'
