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.

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.
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.
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.
Curated set · 4 capabilities
We ship only the actions that matter.
01-04
4 capabilities in this set.
Part of 4 available through Circuit Workout Timer.
- 01
Analyze muscle distribution
This capability checks how your exercises are spread across different muscle groups. It helps you see if your circuit is balanced or if you're overworking certain areas.
- 02
Calculate workout metrics
This capability handles the math for your circuit. It calculates total duration and work-to-rest ratios based on your station count and timing.
- 03
Determine intensity zone
This capability identifies the metabolic intensity zone of your routine. It tells you if a workout is aerobic or falls into another category.
- 04
Validate circuit feasibility
This capability checks if your workout plan is actually doable. It flags routines that have unrealistic rest periods or unsustainable intensity levels.
Real work
What teams actually run
Balanced Circuit Design
Ensure a client's full-body circuit isn't accidentally neglecting their posterior chain.
Time-Constrained Planning
Quickly calculate if a specific set of exercises will fit into a 30-minute window.
Intensity Management
Verify that a high-intensity interval session stays within the intended metabolic zone.
Safety Validation
Check if a high-volume circuit has enough rest to be physically sustainable.
One connector, every AI
Circuit Workout Timer 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.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Circuit Workout Timer 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.

Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Circuit Workout Timer, so you can see the experience inside your AI.
It does not authenticate your account with Circuit Workout Timer. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Circuit Workout Timer owners ask.
- 01
What can this MCP do for my workouts?
It allows your AI client to calculate workout duration, check muscle distribution, determine intensity zones, and validate if a circuit is physically feasible.
- 02
How do I use this with Claude or Cursor?
You connect to the Vinkius-hosted MCP once, and then your AI client can immediately use the capabilities through the standard Model Context Protocol.
- 03
Can it tell me if my workout is too hard?
Yes, the validate_circuit_feasibility capability checks if your parameters are physically logical and sustainable.
- 04
Does it help with muscle imbalances?
Yes, the analyze_muscle_distribution capability evaluates how exercises are spread across muscle groups to ensure balance.
- 05
Do I need to host this myself?
No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.
- 06
How can I check if my workout is balanced?
You can use the analyze_muscle_distribution capability. Provide your list of exercises and a mapping of exercises to muscle groups to receive a balance score.
- 07
Can I calculate the total time for my circuit?
Yes, the calculate_workout_metrics capability calculates the total duration, including all work periods, rest periods between stations, and rest periods between rounds.
- 08
How is the intensity zone determined?
The determine_intensity_zone capability categorizes the workout into metabolic zones like Aerobic or Anaerobic based on the ratio of work time to rest time.
