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.

Who it's for

Built for the work Vitamin D Calculator owners hand off.

This MCP is built for anyone managing nutritional health through data-driven supplementation.

  • 01

    Health Enthusiasts

    People tracking their bloodwork who want specific dosage numbers instead of generic advice.

  • 02

    Nutrition Researchers

    Users who need to model how environmental factors like latitude affect Vitamin D needs.

  • 03

    Biohackers

    Individuals using precise physiological data like BMI and skin type to optimize their intake.

FAQ

Questions Vitamin D Calculator owners ask.

  • 01

    How does this MCP calculate Vitamin D needs?

    It uses a combination of your BMI, skin type, current latitude, and the current season to determine your specific requirements.

  • 02

    Can I use this with Claude or Cursor?

    Yes, you can connect this MCP to any compatible client including Claude, Cursor, Windsurf, or VS Code.

  • 03

    What is a loading dose?

    A loading dose is a higher amount of Vitamin D taken for a short period to quickly raise your levels from a deficient state to a target level.

  • 04

    Does it account for sun exposure?

    Yes, the MCP includes a capability to calculate the efficiency of natural Vitamin D synthesis based on your location and time.

  • 05

    Do I need to host this myself?

    No, Vinkius hosts and manages the MCP for you. You just connect your client and start using the capabilities.

  • 06

    How does skin type affect the calculation?

    The capability uses the Fitzpatrick skin scale to adjust for melanin levels, which influence how efficiently your skin synthesizes Vitamin D from sunlight.

  • 07

    Does BMI impact the recommended dose?

    Yes, because Vitamin D is fat-soluble, higher BMI values may require higher doses to reach optimal serum levels.
