How do I use this MCP with my AI client?

You connect to the MCP through the Vinkius platform. Once connected, you can simply type your lifting data into Claude, Cursor, or any compatible client.

What is Time Under Tension (TUT)?

TUT is the total amount of time a muscle is held under tension during a set, which is determined by your rep count and tempo.

Can this capability help me grow muscle?

Yes, it helps you verify if your tempo and total set duration are sufficient to provide the metabolic stress needed for hypertrophy.

Does it recommend rest times?

Yes, the recommend_rest_period capability suggests recovery durations based on your specific training intensity and goals.

What kind of tempo data do I need to provide?

You should provide the duration for the eccentric, pause, and concentric phases, along with the total number of repetitions.

How do I calculate my total time under tension?

You can use the calculate_set_tut capability by providing the number of repetitions and the duration of the eccentric, pause, and concentric phases.

Can this capability help with muscle growth?

Yes, the analyze_training_goal capability evaluates your TUT to determine its suitability for hypertrophy or strength training.

How much rest should I take between sets?

The recommend_rest_period capability suggests recovery durations based on your specific training goal and the intensity of the set.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Time Under Tension Tracker.

01
Analyze training goal
This capability categorizes whether a set is effective for specific physiological outcomes like strength or hypertrophy.
02
Calculate set tut
Use this to find the total duration of a single set by providing the tempo and repetition count.
03
Get phase distribution
This capability breaks down how much time was spent in each movement phase.
04
Recommend rest period
Get a specific recovery duration suggestion based on your training objectives and intensity.

Real work

What teams actually run

Hypertrophy Verification

Check if your slow eccentric phases are providing enough time under tension for muscle growth.

Strength Optimization

Ensure your rest periods are long enough to recover for high-intensity strength sets.

Tempo Auditing

Analyze the distribution of time across movement phases to ensure consistent movement speed.

Training Program Adjustment

Use the goal analysis capability to see if your current rep schemes are hitting the right physiological targets.

One connector, every AI

Time Under Tension Tracker works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Time Under Tension Tracker to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
