A timing engine for the Aaron Mattes Active Isolated Stretching (AIS) protocol.

4 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides a specialized timing engine for the Aaron Mattes Active Isolated Stretching (AIS) protocol. It helps users manage the precise timing required to avoid the stretch reflex. Use calculate_stretch_cycle to determine the timing for a single repetition, calculate_set_metrics to plan the total duration of a set, get_antagonist_guidance to identify the muscle needed for reciprocal inhibition, and validate_protocol_safety to ensure the requested repetitions and assistance levels are appropriate for the target muscle group.

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

calculate_set_metrics

Calculates the cumulative timing and repetition data for a complete set of stretches

calculate_stretch_cycle

Determines the timing and structure of a single repetition within a stretching set

get_antagonist_guidance

Identifies which muscle must be activated to facilitate the stretch for the target muscle

validate_protocol_safety

Evaluates if the requested parameters are appropriate for a specific muscle group

How long should I hold a stretch for the hamstrings with moderate assistance?

For a hamstring stretch with moderate assistance, the hold duration is 1.5 seconds.

Calculate the total time for 10 reps of a quadriceps stretch with no assistance.

The total time for 10 repetitions of the quadriceps stretch with no assistance is 45 seconds.

Which muscle should I activate to stretch my biceps?

To stretch your biceps, you should actively contract your triceps.

The Active Isolated Stretching (AIS) protocol is designed to increase range of motion and reduce muscle tension by using short, controlled movements that avoid triggering the stretch reflex.
