What your AI can do with compoundsim
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “simulate_portfolio”: Monte Carlo simulation of investing monthly (plus an optional starting sum) in one asset or a mix rebalanced monthly. Returns the range of o.”
“Use “compare_portfolios”: Runs the same monthly-investing plan through 2 to 4 portfolios (the same simulation as simulate_portfolio) and returns each one's final outc.”
“Use “simulate_withdrawal”: Monte Carlo simulation of withdrawing a yearly percentage of a starting balance, raised with inflation every month, from a portfolio (the 4%.”
“Use “simulate_fixed_rate”: Deterministic compound growth of monthly contributions (plus an optional starting sum) at a fixed annual return. Returns contributions, gain.”
How secure is the compoundsim MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how compoundsim holds up.
Security grade A
gate scanned 5 tools on Nov 10, 2026 for prompt injection and risky tool definitions — nothing to flag.
- lowsimulate_portfolio: Unusually long tool description
- lowcompare_portfolios: Unusually long tool description
- lowsimulate_withdrawal: Unusually long tool description
Official endpoint
Operated by compoundsim (compoundsim.app) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If compoundsim adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

simulate_withdrawal — Monte Carlo simulation of withdrawing a yearly percentage of a starting balance, raised with inflation every month, from a portfolio (the 4%
simulate_fixed_rate — Deterministic compound growth of monthly contributions (plus an optional starting sum) at a fixed annual return. Returns contributions, gain
get_asset_returns — 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
Who runs the compoundsim MCP server?
The compoundsim MCP server at a glance
https://compoundsim.app/mcpQuestions, answered
Is there an official compoundsim MCP server?
Yes — compoundsim operates its own remote MCP server at compoundsim.app. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect compoundsim to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick compoundsim in the directory. No account or sign-in is needed. From then on, compoundsim's tools are available in every client you've connected to gate.
Do I need to host anything?
No. compoundsim runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the compoundsim MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect compoundsim in minutes. No credit card required.
