What is the Kelly Criterion?

It is a mathematical formula used to determine the optimal size of a bet to maximize long term growth of a bankroll.

Can I use fractional Kelly staking?

Yes, you can instruct your agent to apply fractional multipliers to reduce the amount wagered and lower risk.

How do I connect this to my AI client?

Vinkius hosts the MCP, so you just connect your client once to the Vinkius catalog to start using the capabilities.

Does this MCP work with different betting odds?

Yes, it is designed to work with decimal odds provided by the user.

Can the agent tell me if a bet is a bad idea?

Yes, the verify_betting_parameters capability checks if your estimated probability is higher than the implied probability of the odds.

How do I use fractional Kelly sizing?

You can use the calculate_kelly_stake capability and provide a kellyFraction value (e.g., 0.5 for Half-Kelly) to reduce volatility and protect your bankroll.

Can I limit my maximum bet amount?

Yes, the calculate_kelly_stake capability accepts a maxStakeCap parameter to ensure the calculated stake does not exceed a specific limit.

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.

How Vinkius works: one connection, every tool, in any AI

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.
