QuantCalc Retirement Engine is a remote MCP server that gives an AI agent 5 tools, among them compare_return_assumptions, explain_methodology, list_return_assumption_sources. It answers at https://mcp.quantcalc.app over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 15 September 2026; the last check, on 20 October 2026, succeeded.
Retirement Monte Carlo, tax-aware withdrawal and Roth-conversion plans, and a 2026 return estimate.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
compare_return_assumptions | Runs the same plan against several published capital market assumption sets and returns the success rate and median outcome under each, showing how far the answer moves with the return forecast used. Inputs: current_age, retirement_age, life_expectancy, current_savings, annual_spending, monthly_contribution |
explain_methodology | Returns what the QuantCalc engine models and what it deliberately leaves out, including the tax provisions that are out of scope, and links to the published methodology. |
list_return_assumption_sources | Returns the published capital market assumption sets the engine carries and which components each publisher provides (returns, volatilities, correlations). |
run_retirement_projection | Runs a Monte Carlo retirement projection on the QuantCalc engine and returns the success rate, the ending-portfolio distribution, and the assumptions that produced them. The result states the return model that ran, the number of paths, and Inputs: current_age, retirement_age, life_expectancy, current_savings, annual_spending, monthly_contribution |
run_tax_aware_projection | Runs the retirement projection with the household's accounts split by tax type and returns the withdrawal order and Roth-conversion programme the engine selected, its present-value advantage and range against drawing traditional first, and Inputs: current_age, retirement_age, life_expectancy, annual_spending, monthly_contribution, social_security |

It answered our last check on 20 October 2026 in 455 ms. Over 4 checks since 15 September 2026 it answered 4. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by quantcalc.app and served from mcp.quantcalc.app, the vendor's own domain: https://mcp.quantcalc.app.
5, as returned by the server's own tools/list on 24 September 2026: compare_return_assumptions, explain_methodology, list_return_assumption_sources, run_retirement_projection, run_tax_aware_projection.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.quantcalc.app. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 15 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
