Context Cost

~4,746Tokens (tool definitions)
~2.3 KBTypical response size
Significant attention impact (3.71% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

⚪mg_calculator_cagr(currencySymbol, beginningValue, endingValue, years)

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_update(sessionId, currencySymbol, beginningValue, endingValue, years, ...)

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).

Update one or more fields in the already-open Market Cap Calculator. ALWAYS call mg_calculator_market_cap_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).

🟢mg_calculator_market_cap_sync(sessionId, currencySymbol, marketCap, sharePrice, sharesOutstanding)

Sync user-entered field values of the open Market Cap 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.

🟢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.

⚪mg_calculator_profit_margin(currencySymbol, revenue, cost)

Open the Profit Margin 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 revenue and cost?", then collect only the input schema fields matching that mode — do not guess or invent field names.

  "type": "object",
  "properties": {

🟡mg_calculator_profit_margin_update(sessionId, currencySymbol, revenue, cost, version)

Update one or more fields in the already-open Profit Margin Calculator.

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).
