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

We ship only the actions that matter.

FAQ

Questions Caffeine Countdown Clock owners ask.

  • 01

    How does this MCP calculate caffeine levels?

    It uses physiological decay principles to model how caffeine concentration decreases in your system over time.

  • 02

    Which AI clients can use this MCP?

    You can use this with any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 03

    Can I use this to plan my morning coffee?

    Yes, you can use the get_latest_safe_timestamp capability to find out when you can have your last cup before bed.

  • 04

    Does this require me to set up my own hosting?

    No, Vinkius hosts and manages the MCP for you, so it is ready to use once you connect.

  • 05

    How accurate are the risk assessments?

    The risk levels are qualitative assessments based on the estimated percentage of caffeine remaining in your system at your target bedtime.

  • 06

    How does the calculation work?

    The capability uses the caffeine half-life (typically 5.5 hours) and a set number of clearance cycles to calculate when your body will have processed enough caffeine to allow for deep sleep.

  • 07

    Can I customize the half-life duration?

    Yes, you can provide a specific halfLifeHours value to the capabilities if you know your metabolism is faster or slower than average.

  • 08

    What does 'High Risk' mean?

    A High Risk status indicates that more than 30% of the caffeine consumed is estimated to still be in your system at your target bedtime.
