# A-share Price Limit Calculator: Regulatory Compliance Tool AI Agent Connect > A-share Price Limit Calculator determines the precise upper and lower price boundaries for stocks traded in the Chinese A-share market. This MCP handles complex regulatory rules across various boards, including the Main Board, ChiNext, STAR Market, and BSE. It's built for financial professionals who need deterministic calculations based on previous closing prices and specific stock statuses. You can check standard volatility rules, calculate exact daily limits, and validate price ticks to ensure compliance with Chinese market standards. Connect this MCP to your AI client and get immediate access to these critical financial calculations. ## Overview - **Category:** finance - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_btWADLY5rBbt96GHj8JHHfQACdTb1qUkhSRXLc83/ai-agent-connect - **Tags:** china, a-share, stock-market, price-limits, finance-tools ## Description The Chinese A-share market has strict, board-specific rules governing daily price movement. Trying to calculate these boundaries manually is a headache because the limits change based on the stock's board, its previous close, and if it carries an ST (Special Treatment) status. This MCP handles that complexity for you. It provides deterministic tools that calculate the exact upper and lower bounds for a single stock. You can check the standard fluctuation percentages assigned to each board using `get_board_configuration`. Then, you feed in the necessary data to `calculate_price_limits` to find the precise daily range. Finally, you can run `validate_price_tick` to confirm that any calculated price adheres to the required 0.01 decimal precision. This MCP keeps your financial analysis accurate and compliant with Chinese market regulations. ## Tools ### calculate_price_limits Calculates the specific upper and lower price boundaries for a single stock ### validate_price_tick 01 precision level. Verifies if a calculated price adheres to standard Chinese market decimal precision ### get_board_configuration Retrieves the standard fluctuation percentages assigned to each stock board ## Prompt Examples **Prompt:** ``` What are the price limits for a Main Board stock with a previous close of 10.00 that is not an ST stock? ``` **Response:** ``` The limit up price is 11.00 and the limit down price is 9.00. ``` **Prompt:** ``` Calculate the limits for a ChiNext stock with a previous close of 50.00. ``` **Response:** ``` The limit up price is 60.00 and the limit down price is 40.00. ``` **Prompt:** ``` What are the limits for an ST stock on the Main Board with a previous close of 5.00? ``` **Response:** ``` The limit up price is 5.25 and the limit down price is 4.75. ``` ## Capabilities ### Determine Price Boundaries The AI uses this MCP to calculate the exact daily upper and lower price limits for a specific A-share stock. ### Check Market Rules The AI runs this tool to retrieve the standard fluctuation percentages assigned to different stock boards. ### Verify Price Accuracy The AI uses this to confirm that a given price adheres to the required 0.01 decimal precision for Chinese markets. ## Use Cases ### Pre-Trade Limit Check Before running a simulation, you need to know the absolute upper and lower bounds for a stock. Use the MCP to calculate the specific price limits. ### Compliance Audit A regulator asks you to verify if a reported price is valid. Use the MCP to validate the price tick against required market standards. ### Market Research You're comparing different boards. Use the MCP to retrieve the standard fluctuation percentages for each board type. ### Scenario Modeling You're modeling a stock that changes status. Use the MCP to calculate the limits based on the stock's current ST status and previous close. ## Benefits - You get the exact daily price boundaries, factoring in Main Board, ChiNext, and STAR Market rules. - The MCP handles complex regulatory variables like ST (Special Treatment) status automatically. - It verifies price ticks, ensuring your data meets the required 0.01 decimal precision. - You save time by accessing standard board configurations without manual lookups. ## How It Works Connecting this MCP gives your AI client direct access to deterministic financial calculations. You simply tell your agent what stock and parameters you need, and the MCP executes the required regulatory check. 1. Connect your preferred AI client (Claude, Cursor, Windsurf, VS Code) to the Vinkius catalog. 2. Your agent identifies the need to calculate A-share price boundaries. 3. The MCP executes the necessary tool, such as calculate_price_limits, using the provided inputs. 4. The MCP returns the precise, compliant upper and lower price bounds directly to your agent. ## Frequently Asked Questions **Does this MCP handle all Chinese stock boards?** Yes. The MCP accounts for specific regulatory rules across multiple boards, including the Main Board, ChiNext, STAR Market, and BSE. **What information does the MCP need to calculate limits?** To calculate the limits, you must provide the stock's previous close price, the specific board it trades on, and whether the stock has ST (Special Treatment) status. **Is this just a general calculator, or is it compliant?** It's a compliant tool. It provides deterministic calculations based on actual Chinese market rules, including validating prices to the required 0.01 decimal precision. **Can I check the standard rules for different boards?** Yes. You can use the get_board_configuration tool to retrieve the standard fluctuation percentages assigned to each stock board.
