Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
compoundsim 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
Compound interest and Monte Carlo simulators for investing, retirement and past asset returns.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http compoundsim-mcp https://compoundsim.app/mcp
# 2 — ask your agent for something these tools do
# simulate_portfolio, compare_portfolios, simulate_withdrawal and 2 more
compoundsim 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 compoundsim-mcp https://compoundsim.app/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.
What you approve
5 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Monte Carlo simulation of investing monthly (plus an optional starting sum) in one asset or a mix rebalanced monthly. Returns the range of outcomes by year (10th to 90th percentile), the deepest fall along the way, the mix's own past return and volatility, and a compoundsim.app url that shows the same scenario.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| portfolio | yes | A preset name or weights in percent by asset (any total; they are scaled to 100). Assets: sp500 = S&P 500, ndx100 = Nasdaq 100, sox = SOX (Semiconductors), schd = US dividend stocks (SCHD), acwi = MSC | |
| initial | number | no | Starting sum invested at once. |
| monthly | number | yes | Amount invested at the end of every month. |
| years | integer | no | Years of investing. |
| inflation_percent | number | no | Annual inflation. When given, every amount out is in today's money at this rate; omitted, amounts are nominal. |
| currency | string | no | Currency of every amount, in and out. In a currency other than USD the paths carry its exchange-rate swings against the dollar (trend removed). Defaults to the language's currency. |
| language | string | no | Language of the page the returned url opens; match the user's language. |
| history | string | no | The span of past monthly returns the model is fitted to: the last 5, 10 or 20 years, or all the data. An asset with less data than the span asked for uses all of its own. |
| history_from | integer | no | First calendar year of a custom span (with history_to); replaces history. |
| history_to | integer | no | Last calendar year of a custom span. |
Runs the same monthly-investing plan through 2 to 4 portfolios (the same simulation as simulate_portfolio) and returns each one's final outcome range, deepest fall, past return and volatility, and url, for questions like 'S&P 500 or all-country stocks?'.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| portfolios | array | yes | The portfolios to compare. |
| initial | number | no | Starting sum invested at once. |
| monthly | number | yes | Amount invested at the end of every month. |
| years | integer | no | Years of investing. |
| inflation_percent | number | no | Annual inflation. When given, every amount out is in today's money at this rate; omitted, amounts are nominal. |
| currency | string | no | Currency of every amount, in and out. In a currency other than USD the paths carry its exchange-rate swings against the dollar (trend removed). Defaults to the language's currency. |
| language | string | no | Language of the page the returned url opens; match the user's language. |
| history | string | no | The span of past monthly returns the model is fitted to: the last 5, 10 or 20 years, or all the data. An asset with less data than the span asked for uses all of its own. |
| history_from | integer | no | First calendar year of a custom span (with history_to); replaces history. |
| history_to | integer | no | Last calendar year of a custom span. |
Monte Carlo simulation of withdrawing a yearly percentage of a starting balance, raised with inflation every month, from a portfolio (the 4% rule and its variants). Returns the share of paths that still had money at the end, when the others ran out, the remaining balance range in today's money, the success rate at withdrawal rates from 2% to 8%, and a compoundsim.app url.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| portfolio | yes | A preset name or weights in percent by asset (any total; they are scaled to 100). Assets: sp500 = S&P 500, ndx100 = Nasdaq 100, sox = SOX (Semiconductors), schd = US dividend stocks (SCHD), acwi = MSC | |
| balance | number | yes | Starting balance. |
| withdrawal_rate_pct | number | no | First year's withdrawal as a percentage of the starting balance. |
| years | integer | no | Years the money has to last. |
| inflation_percent | number | no | Annual inflation the withdrawals rise with; balances are in today's money. |

| language | string | no | Language of the page the returned url opens; match the user's language. |
| history | string | no | The span of past monthly returns the model is fitted to: the last 5, 10 or 20 years, or all the data. An asset with less data than the span asked for uses all of its own. |
| history_from | integer | no | First calendar year of a custom span (with history_to); replaces history. |
| history_to | integer | no | Last calendar year of a custom span. |
Deterministic compound growth of monthly contributions (plus an optional starting sum) at a fixed annual return. Returns contributions, gains and total by year, and a compoundsim.app url. Use simulate_portfolio for the range of outcomes of real assets.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| initial | number | no | Starting sum invested at once. |
| monthly | number | yes | Amount invested at the end of every month. |
| years | integer | no | Years of investing. |
| inflation_percent | number | no | Annual inflation. When given, every amount out is in today's money at this rate; omitted, amounts are nominal. |
| annual_return_pct | number | no | Effective annual return (CAGR), applied as the equivalent monthly rate. |
| currency | string | no | Currency of every amount, in and out. In a currency other than USD the paths carry its exchange-rate swings against the dollar (trend removed). Defaults to the language's currency. |
| language | string | no | Language of the page the returned url opens; match the user's language. |
Annualised past returns of the assets compoundsim simulates, over the last 5, 10 or 20 years, all the data, or a calendar span: total return with dividends reinvested, price return, the dividends' share, volatility, and the return after US inflation (in USD) or the exchange rate's share of the return (in another currency).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| assets | array | no | Assets to include; all of them when omitted. |
| period | string | no | The span measured: the last 5, 10 or 20 years, or all the data. An asset with less data than the span asked for uses all of its own. |
| period_from | integer | no | First calendar year of a custom span (with period_to); replaces period. |
| period_to | integer | no | Last calendar year of a custom span. |
| currency | string | no | Currency of every amount, in and out. In a currency other than USD the paths carry its exchange-rate swings against the dollar (trend removed). Defaults to the language's currency. |
| language | string | no | Language of the page the returned url opens; match the user's language. |

ATool-list grade · score 96 / 100
Release 1.0.0 · scanned 2 Nov 2026
Graded from the tools this server lists, not from its source code.
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.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

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 compoundsim 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.
