How do I use this with Claude?

You connect the MCP through Vinkius. Once connected, you can simply ask Claude to calculate your fasting windows or check your travel itinerary.

Can this MCP prevent me from over-fasting?

Yes. By using the safety threshold capability, your agent can monitor your fasting duration and warn you if a flight might push you past your limits.

Does it work for any timezone?

Yes, it calculates the delta between your starting point and your destination to adjust your feeding windows.

What happens if my flight is delayed?

You can provide the updated flight duration to your agent, and it will recalculate your new feeding window based on the new arrival time.

Do I need to provide my own timezone math?

No. The MCP handles the timezone shifts and flight durations automatically.

How does the capability handle timezone changes?

The calculate_fast_window_shift capability calculates the total elapsed time from your fast start to arrival, then adjusts for the destination's UTC offset to provide a new feeding window.

What does it mean if my fast is 'broken'?

A broken fast occurs when the timezone shift causes your scheduled feeding window to start earlier than originally planned, potentially forcing you to eat prematurely.

Can I check if my flight schedule is valid for fasting?

Yes, you can use validate_travel_timeline to ensure your feeding start time and flight departure are logically compatible.

Waiting for input…

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.

Curated set · 3 capabilities

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Timezone Fast Shifter.

01
Get fasting safety thresholds
This capability retrieves your maximum allowed fasting duration. It helps your agent stay within your specific safety boundaries.
02
Validate travel timeline
Use this to check if your flight schedule and fasting goals actually work together. It flags logical errors, like if a flight departs before your fast even begins.
03
Calculate fast window shift
This capability determines your new feeding window at your destination. It accounts for the timezone change and flight duration to give you a precise time to eat.

One connector, every AI

Timezone Fast Shifter 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 Timezone Fast Shifter 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.
