How does this MCP calculate bedtimes?

It uses 90-minute circadian cycles to find windows that allow you to wake up at the end of a cycle.

Can I use this with Claude?

Yes, you can connect this MCP to any MCP-compatible client including Claude, Cursor, and Windsurf.

Does it account for how long it takes me to fall asleep?

Yes, you can include your sleep latency in your request so the agent provides accurate bedtime options.

How does it determine if I got enough sleep?

The capability evaluates your sleep duration against the biological needs of your specific age group.

Will it help with jet lag?

Yes, it can calculate the necessary circadian adjustment period for your specific time zone shifts.

How do 90-minute sleep cycles work?

The human sleep pattern is composed of repeating cycles that typically last approximately 90 minutes. Using calculate_bedtimes helps you wake up at the end of a cycle to minimize sleep inertia.

Can I check if I am getting enough sleep?

Yes, you can use evaluate_sleep_adequacy to compare your total sleep duration against the minimum requirements for your age group.

How do I adjust for jet lag?

You can use calculate_jet_lag_adjustment to determine how many days you need to adjust your internal clock based on the number of time zones you cross.

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

01-03

3 capabilities in this set.

Part of 3 available through Sleep Cycle Calculator.

01
Calculate bedtimes
This capability finds the best times to go to bed to ensure you wake up at a specific time after completing full 90-minute cycles.
02
Calculate jet lag adjustment
This capability determines how many days of circadian adjustment you'll need based on your travel distance and time zone shifts.
03
Evaluate sleep adequacy
This capability checks if your planned or actual sleep duration meets the biological requirements for your specific age group.

Real work

What teams actually run

Morning Routine Planning

Tell your agent your wake time to get a list of ideal bedtimes.

Travel Itinerary Management

Use the capability to figure out how many days of downtime to expect after a long flight.

Health Tracking

Check if your current sleep duration is actually sufficient for your age.

Sleep Optimization

Find the best time to sleep to avoid waking up mid-cycle.

One connector, every AI

Sleep Cycle Calculator 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 Sleep Cycle Calculator 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.
