# Bankroll Kelly Calculator AI Agent Connect

> Bankroll Kelly Calculator MCP gives your AI agent the mathematical framework to manage betting capital. It uses the Kelly Criterion to determine optimal stake sizes based on your bankroll, decimal odds, and estimated win probabilities. You can apply fractional multipliers to control risk or set caps to protect your capital.

## Description

You can stop guessing how much to wager on a match. This MCP gives your AI client the exact math needed to apply the Kelly Criterion to your betting strategy. Instead of relying on gut feeling, you provide your agent with your current bankroll, the decimal odds, and your estimated probability of a win. The agent then runs the numbers to find the mathematically optimal stake. If you want to play it safer, you can instruct your agent to use fractional Kelly multipliers, which helps reduce volatility. It also handles the heavy lifting of checking if a bet is even worth taking by comparing your estimated probability against the implied probability of the odds. Whether you are managing a large bankroll or testing a new strategy, this tool keeps your risk management consistent and grounded in probability theory.

## Tools

### calculate_kelly_stake
This tool calculates the optimal stake size by processing your bankroll, the decimal odds, and your estimated win probability.

### compare_risk_profiles
Use this to see how different fractional Kelly strategies change your risk exposure.

### get_bankroll_summary
This tool provides a quick overview of your current betting capacity.

### verify_betting_parameters
This tool checks if your input odds and probabilities are mathematically sound before you place a bet.

## Prompt Examples

**Prompt:** 
```
Calculate the stake for a $1000 bankroll with decimal odds of 2.0 and a 55% estimated probability.
```

**Response:** 
```
The edge is 10%, the full Kelly stake is $100.00, and the applied stake is $100.00.
```

**Prompt:** 
```
I have $500. What is the stake for odds of 3.0 and a 40% probability using a Half-Kelly approach?
```

**Response:** 
```
The edge is 20%, the full Kelly stake is $50.00, and the applied stake is $25.00.
```

**Prompt:** 
```
Check if a bet with odds of 1.5 and a 60% probability is mathematically viable.
```

**Response:** 
```
Yes, the bet is mathematically viable as the estimated probability is greater than the implied probability.
```

## Frequently Asked Questions

**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 tools.

**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 tool 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` tool 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?**
