It's easy to over-leverage when you feel confident, but math offers a way to stay disciplined. This Connector takes the guesswork out of capital allocation by applying the Kelly Criterion formula to your specific numbers. You can quickly find out what the mathematically perfect bet size is or dial it back for a safer approach if you're trying to preserve your capital over the long haul. It also handles the tedious work of converting different types of market odds into usable profit ratios, making sure your math is consistent across different platforms. When you use this through the Vinkius catalog, your AI client becomes a specialized risk management assistant. Instead of manually crunching numbers in a spreadsheet, you just feed the AI the raw data, and it gives you the exact percentage to risk. It even checks your inputs to make sure the math actually works before you commit. It's about moving from a gut feeling to a disciplined, mathematical strategy for managing your money. You get a reliable way to handle the heavy lifting of risk analysis without having to do the manual arithmetic yourself every time you see a new opportunity. ## Tools ### get_net_odds_ratio Translates American odds into the net profit-to-stake ratio. This keeps your math consistent across different betting platforms. ### validate_betting_parameters Ensures all your inputs are mathematically sound before you run any Kelly calculations. It prevents errors caused by impossible odds or probabilities. ### calculate_half_kelly Provides a safer, more conservative wagering fraction for long-term bankroll preservation. This is the standard for reducing variance. ### calculate_pure_kelly Finds the maximum mathematically optimal percentage of your bankroll to wager. Use this for maximum growth when you have high confidence in your edge. ## Prompt Examples **Prompt:** ``` What is the optimal bet size for a game with a 55% win probability at -110 American odds? ``` **Response:** ``` Based on the data provided, here is the optimal wager size: * **Wager Size:** 4.35% of your bankroll * **Strategy:** Pure Kelly * **Net Profit Ratio:** 0.909 This calculation shows the maximum mathematically optimal amount to risk based on your edge. ``` **Prompt:** ``` Calculate a safe bet size for an underdog with +150 odds and a 40% chance of winning. ``` **Response:** ``` For a more conservative approach using the Half Kelly strategy, you should wager **7.5% of your bankroll**. This helps preserve your capital over the long term by reducing the impact of variance while still taking advantage of your calculated edge. ``` **Prompt:** ``` Convert +200 American odds to a net profit ratio. ``` **Response:** ``` The net profit ratio for **+200** American odds is **2.0**. This means for every dollar you stake, you stand to gain two dollars in profit, assuming a win. ``` ## Capabilities ### Calculate optimal wager percentages Find the exact percentage of your bankroll to risk based on win probability. ### Apply conservative betting fractions Use a safer wagering fraction to protect your capital over the long term. ### Convert market odds to profit ratios Turn different types of market odds into a standard profit-to-stake ratio. ### Check if betting inputs are valid Verify that your win probabilities and odds are mathematically sound before calculating. ### Manage bankroll risk levels Switch between aggressive and conservative risk models instantly. ## Use Cases ### Calculating a sports bet size A sports bettor wants to know the bet size for a 55% win chance at -110 odds.

It removes the guesswork from bankroll management. **How do I use Kelly Criterion Sizing MCP for sports betting?** You tell your AI client the odds and your estimated win percentage. The Connector then calculates the best bet size for you using standard risk management formulas. **Can Kelly Criterion Sizing MCP help me avoid losing my bankroll?** Yes. By using the Half Kelly calculation, you can take a more conservative approach that prioritizes long-term capital preservation over maximum immediate growth. **What are American odds in Kelly Criterion Sizing MCP?** The tool can take standard American odds and convert them into a net profit ratio, making it easier to run your math consistently across different betting platforms. **Is Kelly Criterion Sizing MCP just for sports?** While popular for sports betting, it's useful for any scenario involving capital allocation, such as poker, crypto trading, or any other high-risk financial activity. **Does Kelly Criterion Sizing MCP tell me who will win?** No, it doesn't predict winners. You must provide the win probability yourself. The Connector only handles the math of how much to wager once you have that information. **What is the difference between Pure Kelly and Half Kelly?** Pure Kelly calculates the maximum mathematically optimal percentage of your bankroll to wager. Half Kelly divides that result by two, providing a safer buffer against volatility and estimation errors. **How do I use American odds with this tool?** You can input standard American format odds, such as -110 for favorites or +150 for underdogs. The `get_net_odds_ratio` tool will handle the conversion to a profit ratio automatically. **Can I verify if my win probability is valid?** Yes, you can use the `validate_betting_parameters` tool to check if your win probability (between 0 and 1) and American odds are mathematically valid for calculation.
