How does this MCP help with sleep?

It uses your sleep cutoff time to calculate when you should stop consuming caffeine so that metabolic levels are low enough for rest.

Can I use this with Claude or Cursor?

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

Does it track my actual consumption?

The MCP provides capabilities to validate your intake and calculate how much capacity you have left based on the data you provide to your AI client.

What kind of math does it do?

It performs calculations for caffeine half-lives, daily milligram limits, and optimal dosing schedules.

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.

How do I plan my caffeine intake for the day?

You can use the get_optimal_schedule capability by providing your desired servings, your daily limit, and your sleep cutoff time.

Can I check if I have exceeded my daily caffeine limit?

Yes, use validate_intake_compliance to verify if your consumed servings adhere to your daily limit and sleep cutoff.

How much caffeine will be left in my system later tonight?

You can estimate this using predict_caffeine_levels by providing your previous servings, a target time, and the caffeine half-life.

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 · 4 capabilities

One connector, every AI

Caffeine Timing Calendar 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 Caffeine Timing Calendar 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.
