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.

FAQ

Questions Refinery Economics owners ask.

  • 01

    How do I use this MCP with my AI client?

    You connect your client, such as Claude or Cursor, to Vinkius once. After that, your agent can call the refinery capabilities directly through the interface.

  • 02

    Can this MCP optimize my crude slate?

    Yes, the optimize_slates capability finds the best combination of crude grades and product yields to maximize net margin.

  • 03

    Does it calculate net margin or just gross margin?

    It does both. You can use calculate_gross_margin for initial profitability or calculate_net_margin to include operating costs.

  • 04

    What is a crack spread calculation?

    The calculate_crack_spread capability calculates the difference between the price of a crude oil and the petroleum products refined from it.

  • 05

    Do I need to host this myself?

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

  • 06

    How do I calculate the net margin?

    You can use the calculate_net_margin capability by providing the gross margin data and the total operating costs.

  • 07

    What is a crack spread?

    A crack spread is the difference between the price of a barrel of crude oil and the value of the refined products produced from it. Use calculate_crack_spread to find this value.

  • 08

    Can I optimize my crude selection?

    Yes, the optimize_slates capability evaluates different crude and product combinations to find the maximum net margin.
