Nothing to run from here
Calculators is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
FIRE & retirement calculators + a multi-currency portfolio rebalancer (exact buy/sell trades).
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http retirecrunch-calculators-mcp https://mcp.retirecrunch.com/mcp
# 2 — ask your agent for something these tools do
# calculate_fire_target, calculate_coast_fire, compute_swiss_property_tax and 5 more
Calculators costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http retirecrunch-calculators-mcp https://mcp.retirecrunch.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

8 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Return RetireCrunch's historical portfolio return profiles for a currency. Each profile is a (return %, volatility %) pair derived from real index data — useful for grounding the assumptions in calculate_fire_target / project_wealth_plan in something defensible rather than guessing.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| currency | string | yes | Currency code; the historical return profiles are denominated in this currency. |
Rebalance a multi-currency portfolio: given holdings, per-holding (or per-asset-class) target weights, cash and FX rates, return the exact BUY/SELL trades to reach the targets, the per-currency cash movements (flagging foreign-cash overdrafts), and a summary. Planning math only — no transaction costs or taxes.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| base_currency | string | no | Base currency the portfolio is valued in. |
| fx_rates | object | no | Value of 1 unit of each currency in the base currency (base currency itself is 1). |

| holdings | array | yes | The portfolio holdings to rebalance. |
| class_targets | object | no | Optional per-asset-class goal % (incl. "Cash"). When given, unlocked holdings are retargeted to hit each class goal before computing trades. |
Open the user's Interactive Brokers portfolio in the RetireCrunch Portfolio Rebalancer.

Returns a private link that works once, for 15 minutes — give it to the user exactly as written. No login is needed because the link itse

| balances | array | no | The balances array from IBKR get_account_balances, unchanged (gives per-currency cash). |

Fetch the rebalancing trades the user decided on in the RetireCrunch Rebalancer, from the plan code they copied ("Send plan to my AI"). Codes work once, for 15 minutes. Returns the trades with IBKR contract ids where known. To act on them, create one IBKR order instruction per trade (create_order_instruction); the user reviews and submits each one inside IBKR. RetireCrunch never places orders.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| code | string | yes | The plan code the user copied from the RetireCrunch Rebalancer ("Send plan to my AI"). |

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.3.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Calculators can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
