What this server can do
17 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
mg_calculator_cagr(years, endingValue, beginningValue, currencySymbol)- Open the CAGR Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → collect only the input schema fields — do not guess or invent field names.
mg_calculator_cagr_state(sessionId)- Read the current field values of the open CAGR Calculator. Call this before answering any question about the current values — the user may have changed fields manually in the GUI. Do not call this on a loop; call it once on demand. Required: sessionId.
mg_calculator_cagr_sync(years, sessionId, endingValue, beginningValue, currencySymbol)- Sync user-entered field values of the open CAGR Calculator back to the session store so the model can read them via the state tool. Called by the View after any field change; hidden from the model. Required: sessionId.
mg_calculator_cagr_update(years, version, sessionId, endingValue, beginningValue, currencySymbol)- Update one or more fields in the already-open CAGR Calculator. ALWAYS call mg_calculator_cagr_state first — the user may have changed values manually in the GUI and you must not overwrite them. Pass the version you received from that call (or from the open tool if updating immediately after opening). Only pass the fields the user explicitly asked to change; omit all others. Send all changes in a single call — multiple sequential calls lose intermediate updates (only the last one applies). Required: sessionId, version.
mg_calculator_dividend(mode, bsShares, baReinvest, bsReinvest, bsSharePrice, currencySymbol, baDepositAmount, baDepositMonths, baDividendYield, baInflationRate, bsDividendYield, bsInflationRate, baProjectionPeriod, bsProjectionPeriod, baInitialInvestment, baDividendGrowthRate, bsDividendGrowthRate, baSharePriceGrowthRate, bsSharePriceGrowthRate)- Open the Dividend Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → ask "By amount invested or by number of shares?", then collect only the input schema fields matching that mode — do not guess or invent field names.
mg_calculator_dividend_state(sessionId)- Read the current field values of the open Dividend Calculator. Call this before answering any question about the current values — the user may have changed fields manually in the GUI. Do not call this on a loop; call it once on demand. Required: sessionId.
mg_calculator_dividend_sync(mode, bsShares, sessionId, baReinvest, bsReinvest, bsSharePrice, currencySymbol, baDepositAmount, baDepositMonths, baDividendYield, baInflationRate, bsDividendYield, bsInflationRate, baProjectionPeriod, bsProjectionPeriod, baInitialInvestment, baDividendGrowthRate, bsDividendGrowthRate, baSharePriceGrowthRate, bsSharePriceGrowthRate)- Sync user-entered field values of the open Dividend Calculator back to the session store so the model can read them via the state tool. Called by the View after any field change; hidden from the model. Required: sessionId.
mg_calculator_dividend_update(mode, version, bsShares, sessionId, baReinvest, bsReinvest, bsSharePrice, currencySymbol, baDepositAmount, baDepositMonths, baDividendYield, baInflationRate, bsDividendYield, bsInflationRate, baProjectionPeriod, bsProjectionPeriod, baInitialInvestment, baDividendGrowthRate, bsDividendGrowthRate, baSharePriceGrowthRate, bsSharePriceGrowthRate)- Update one or more fields in the already-open Dividend Calculator. ALWAYS call mg_calculator_dividend_state first — the user may have changed values manually in the GUI and you must not overwrite them. Pass the version you received from that call (or from the open tool if updating immediately after opening). Only pass the fields the user explicitly asked to change; omit all others. Send all changes in a single call — multiple sequential calls lose intermediate updates (only the last one applies). Required: sessionId, version.
mg_calculator_market_cap(marketCap, sharePrice, currencySymbol, sharesOutstanding)- Open the Market Cap Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → ask "Would you like to pre-fill share price and shares outstanding?", then collect only the input schema fields matching that mode — do not guess or invent field names.
mg_calculator_market_cap_state(sessionId)- Read the current field values of the open Market Cap Calculator. Call this before answering any question about the current values — the user may have changed fields manually in the GUI. Do not call this on a loop; call it once on demand. Required: sessionId.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
