# Implied Probability Extractor MCP for AI Agents MCP > The Implied Probability Extractor helps bettors and analysts strip bookmaker margins from American odds. It converts standard sportsbook odds into true implied probabilities, allowing you to see the underlying fair market value of any sporting outcome. You can identify betting discrepancies by removing the 'vig' (bookmaker margin) automatically. ## Overview - **Category:** finance - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_6uihQnjCBDnbzu7nnPLC9eBf0XhY9qCxip46V2oE/mcp - **Tags:** betting, odds, probability, sportsbook, analytics ## Description When you look at sports odds, you aren't seeing the true probability; you're seeing what the bookmaker wants you to bet. This MCP strips that built-in profit margin—the vig—from American odds. It gives you a clear picture of the underlying fair market probabilities for any game. You can use this connection to compare de-viggered numbers against your own projections, which is critical for finding genuine value in betting lines. While many services offer odds conversion, connecting through Vinkius lets your AI client access this precise financial utility alongside thousands of other specialized tools. This means you're not just calculating probabilities; you're running a full analytical comparison that tells you where the real money is. ## Tools ### calculate_overround_percentage Determines the total margin, or 'vig', being charged by a bookmaker across multiple odds. ### get_raw_probabilities Converts American odds into unadjusted raw implied probabilities without removing any margins. ### get_true_probabilities Removes the bookmaker's margin to provide fair market probabilities, revealing the underlying true value of the odds. ## Prompt Examples **Prompt:** ``` What are the true probabilities for a game where one side is at -150 and the other is at +120? ``` **Response:** ``` **Odds Analysis Report** The bookmaker's margin (vig) on this line is 7.89%. Here are the calculated fair market probabilities: * **Outcome A:** 45.6% (True Probability) * **Outcome B:** 54.4% (True Probability) This shows Outcome A has a better value than the odds suggest. ``` **Prompt:** ``` Calculate the overround for these three outcomes: [-100, +200, -300] ``` **Response:** ``` **Overround Calculation** Based on the odds provided: * Total Overround (Vig): **8.5%** * This means 8.5% of your money is going to the bookmaker's profit pool, not on payouts. Always factor this margin into your final decision. ``` **Prompt:** ``` Convert these odds to their raw implied probabilities: [-130, -130] ``` **Response:** ``` **Raw Probability Conversion** The unadjusted raw implied probabilities are: * **Outcome 1:** 54.17% * **Outcome 2:** 54.17% Note: These numbers include the bookmaker's margin, so use this for a quick check only. ``` ## Capabilities ### Determine Bookmaker Margin Calculate the total margin (the 'vig') being charged across a set of odds. ### Convert Odds to Raw Probabilities Instantly converts American odds into unadjusted raw implied probabilities for quick analysis. ### Calculate Fair Market Probability Removes the bookmaker's margin from given odds, providing true market-based probabilities. ## Use Cases ### Finding Value in NFL Point Spreads A user spots a mismatch between two major sportsbooks' odds for an upcoming game. They ask their agent to use `get_true_probabilities` on both sets of lines. The MCP reveals that one book is significantly underpricing the outcome, directing the user to place a better bet. ### Auditing Bookmaker Profit Margins A betting analyst needs to check if a new sportsbook is charging standard margins. They feed the odds into `calculate_overround_percentage`, and the MCP immediately returns the total vig, allowing for rapid competition analysis. ### Comparing Odds Across Different Markets A bettor needs to compare win/loss probabilities across different types of bets (e.g., moneyline vs. spread). By using `get_raw_probabilities`, the agent generates a baseline percentage for every outcome, making comparison straightforward. ### Modeling Future Market Behavior A quantitative analyst builds a financial model that predicts market volatility. They use the MCP to adjust historical odds by calculating `get_true_probabilities`, ensuring their model reflects real-world, margin-free risk. ## Benefits - Instantly calculate the bookmaker's margin: Use `calculate_overround_percentage` to figure out exactly what percentage of your bet is going straight to profit. - Identify true value with `get_true_probabilities`: This function strips away the vig, showing you the actual underlying probability of an outcome regardless of the sportsbook’s line. - Quickly generate preliminary data: Use `get_raw_probabilities` when you need a fast, unadjusted look at how the odds translate into percentages for initial comparison. - Compare multiple sources efficiently: Run all three utilities on different sets of odds to build a comprehensive analysis that pinpoints discrepancies in market pricing. - Cut down research time: Stop wasting time manually running complex probability formulas; let your agent handle the math and give you actionable data points. ## How It Works The bottom line is you get three distinct views of your odds—the bookmaker's view, the unadjusted view, and the actual fair market view. 1. You provide your AI client with a set of American odds (e.g., -110, +150) and the outcome you want analyzed. 2. The MCP processes these numbers by first calculating the total overround percentage to identify the margin charged. 3. It then provides multiple outputs: the raw probabilities, the calculated margin, and finally, the true implied probability after stripping out the vig. ## Frequently Asked Questions **How does the Implied Probability Extractor MCP help me find value in sports betting?** It helps you by stripping out the bookmaker's profit margin (the vig) from displayed odds. This reveals the true, underlying probability of an outcome, letting you compare what the market *should* be versus what the sportsbook is offering. **What is the difference between raw and true probabilities using this MCP?** Raw probabilities are simple conversions that include the bookmaker's margin. True probabilities, which you get from the Implied Probability Extractor, have had that profit margin removed to show the fair market chance. **Can I use this MCP if the odds I am looking at aren't standard American format?** While it specializes in American odds, you can feed your agent a variety of numbers. The MCP is designed to analyze the structure and calculate the margin regardless of minor variations. **Does the Implied Probability Extractor only work for single outcomes?** No. You can use it on multiple outcomes at once, which allows you to compare probabilities across an entire game or market simultaneously in one request. **Is this MCP better than just using a general odds calculator?** Yes. A basic calculator only converts numbers; the Implied Probability Extractor calculates and removes the bookmaker's profit margin, giving you actionable data that tells you where the real risk lies. **How do I use the Implied Probability Extractor to audit a sportsbook?** You run the odds through the overround percentage calculator. This immediately shows you the total margin being charged by the bookmaker, giving you an instant assessment of their profit structure.
