# Mass Index Calculator MCP for AI Agents AI Agent Connect > Mass Index Calculator MCP identifies market reversals and momentum shifts. It uses the Donald Dorsey Mass Index to detect volatility compression and subsequent explosive price movements, helping you spot trend changes and momentum bulges before they happen. ## Overview - **Category:** finance - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_rA4oYC8ZhfXrZfMiZqTdLcBTFY8G95UW0du79uT2/ai-agent-connect - **Tags:** mass-index, reversal, volatility, momentum, trading ## Description Trading is often a game of waiting for the right moment of volatility. Most traders spend hours staring at charts, trying to distinguish between a quiet market and one that is just building up pressure for a massive move. This MCP changes that by bringing deterministic technical analysis directly into your AI agent's workflow. Instead of manually calculating indicators or squinting at volatility bands, you can simply ask your agent to scan price data for specific patterns. It identifies when the market is squeezing tight and when that pressure is about to release into a breakout. By connecting this to your preferred AI client through the Vinkius catalog, you turn a standard chat interface into a sophisticated technical analysis workstation. You can pinpoint exact reversal zones or find those specific periods where momentum is building up, allowing you to focus on execution rather than constant manual monitoring. ## Tools ### calculate_mass_index Generates a complete Mass Index series from your price data. It uses smoothing parameters to turn raw highs and lows into a clean volatility indicator. ### detect_reversal_signals Scans the indicator for specific threshold crossings. It finds the exact moments when price setups suggest a trend change is coming. ### identify_bulge_formations Locates periods of intense, sustained momentum. It highlights when the Mass Index stays high, signaling a strong trend build. ## Prompt Examples **Prompt:** ``` Can you check these prices for any reversal signals? ``` **Response:** ``` I've analyzed the price data provided. **Reversal Analysis:** - **Status:** Reversal signal detected. - **Location:** Index 4 - **Details:** The Mass Index crossed the upper threshold, suggesting a transition from volatility compression to an active trend change. ``` **Prompt:** ``` Calculate the Mass Index for this data and tell me if there's a momentum bulge. ``` **Response:** ``` I have calculated the Mass Index series for your dataset. | Index | Mass Index Value | |-------|------------------| | 1 | 12.4 | | 2 | 14.8 | | 3 | 28.5 | | 4 | 31.2 | **Finding:** A **momentum bulge** was identified between Index 3 and Index 4, indicating a significant increase in volatility. ``` **Prompt:** ``` Are we in a period of low volatility right now based on the Mass Index? ``` **Response:** ``` Based on the current series, the market is in a **low-volatility state**. The Mass Index is currently at **8.2**, which is well below the typical threshold for momentum expansion. This suggests the market is currently in a compression phase. ``` ## Capabilities ### Spot market reversals Find specific price trigger and confirmation zones using Mass Index threshold movements. ### Detect volatility squeezes Identify periods where price movement is compressing before an explosive breakout. ### Track momentum builds Locate sustained high-volatility periods that indicate strong directional momentum. ### Generate indicator series Create a full Mass Index series from raw price data and custom smoothing settings. ## Use Cases ### Catching a breakout after a squeeze A trader notices a stock is flat and asks their agent to check for Mass Index compression to see if a breakout is imminent. ### Confirming a trend reversal An analyst uses the tool to verify if a recent price drop is a true reversal or just a temporary dip in volatility. ### Filtering out low-momentum noise A quant uses the tool to ignore markets that lack the necessary momentum bulges required for their specific strategy. ### Automating technical scanning A developer feeds daily price history to their agent to find all assets currently showing high Mass Index values. ## Benefits - Automate volatility scanning by letting your agent process large datasets instantly. - Identify explosive price moves by spotting compression zones with detect_reversal_signals. - Find sustained trends using identify_bulge_formations to catch momentum early. - Remove manual calculation errors by using deterministic math via calculate_mass_index. - Speed up decision-making by getting direct reversal alerts instead of reading raw charts. ## How It Works The bottom line is you turn raw price data into actionable volatility signals through a simple conversation. 1. Feed your price data, including highs and lows, into your AI client. 2. Ask your agent to run the Mass Index calculations and scan for specific patterns. 3. Receive clear signals regarding reversals, momentum bulges, or volatility shifts. ## Frequently Asked Questions **How can the Mass Index Calculator help my trading strategy?** It helps you identify periods of low volatility that often precede large price moves, allowing you to prepare for breakouts before they happen. **Can I use the Mass Index Calculator with any price data?** Yes, as long as you provide the high and low price data, the tool can generate the indicator series for your analysis. **How does the Mass Index Calculator detect market reversals?** It monitors how the Mass Index moves through specific threshold zones, signaling when volatility is shifting from a squeeze to an expansion. **Is the Mass Index Calculator compatible with Claude?** Yes, you can connect this MCP to Claude or any other MCP-compatible client to perform these technical analyses through your chat interface. **What is the difference between a reversal and a bulge in this tool?** A reversal signal identifies a change in the volatility state, while a bulge identifies a period of sustained, high-intensity momentum.
