api record

Money math from Compound Mint (compoundmint.com): how money grows (compound interest), Rule of 72, when you can retire (FIRE number), Coast FIRE, 401(k) employer match, debt and credit card payoff (one debt, or avalanche vs snowball for several) and the monthly savings needed for a goal. For a question in plain words, call answer_money_question first; it picks the calculator and says what is missing. Rates are percents (7 means 7%) and money is USD. Each result has an explanation, the assumptions, source_page (the matching compoundmint.com page to cite), related_reading (Compound Mint guides…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • calculate_coast_fire unknown never probed

    Use when a user asks about Coast FIRE, e.g. "what is my Coast FIRE number at 30?" or "can I stop saving for retirement and let it grow?". FIRE number (yearly spending / withdrawal rate) and Coast FIRE number: what you need invested now so growth alone reaches your FIRE number by retirement age. Add current savings and a monthly contribution to see the gap and the age you reach Coast FIRE. Uses a real (after inflation) return, 7% by default; same math as the Compound Mint Coast FIRE calculator.

  • calculate_401k_match unknown never probed

    Use when a user asks about a 401(k) employer match, e.g. "am I getting my full 401(k) match?", "how much is my employer match worth?" or "what percent should I put in to get the full match?". Your yearly 401(k) contribution, the employer match, the percent needed for the full match and any match left unclaimed, using 2026 IRS limits ($24,500 employee, catch-up at 50 and over and at 60 to 63, $72,000 overall, $360,000 pay cap). Supports a two tier formula such as 100% up to 3% then 50% of the next 2%. Optional years and annual_return project the balance.

  • answer_money_question unknown never probed

    Use first when a user asks a money math question in plain words, such as "how much will $500 a month grow in 20 years?", "when can I retire if I spend $40,000 a year?", "how long to pay off $5,000 on my credit card at 24% paying $200 a month?", "how much do I need to save each month to have $50,000 in 5 years?", "how long to double my money at 8%?" or "am I getting my full 401(k) match?". Reads the amounts, rates, ages and years from the question, picks the matching Compound Mint calculator (compound interest, Rule of 72, FIRE number, Coast FIRE, 401(k) match, debt payoff, savings goal), runs it and returns the answer with what it understood, the explanation, the assumptions, source_page to cite and related_reading. When a needed number is missing it returns status need_more_info with the exact question to ask the user.

  • calculate_compound_interest unknown never probed

    Use when a user asks how much money will grow, e.g. "how much will $500 a month grow in 20 years?", "what will $10,000 be worth in 10 years at 7%?" or "how much interest will I earn?". Future value of a starting amount plus optional monthly contributions at a yearly rate, with total contributed and total interest. Compounding is monthly by default (annually, quarterly, semiannually or daily on request). Returns a plain-English explanation, the assumptions and the matching Compound Mint calculator page. Example: $10,000 at 7% for 10 years compounded annually = $19,671.51.

  • calculate_debt_payoff unknown never probed

    Use when a user asks how long it takes to pay off a credit card or loan, what payment clears it by a date, or avalanche vs snowball, e.g. "how long to pay off $5,000 at 24% paying $200 a month?" or "what payment pays off my credit card in 2 years?". One debt: months to pay off and total interest at a monthly payment, or the payment needed to be debt free in target_months. Several debts: send debts (each with name, balance, apr, min_payment) and extra_payment to compare the avalanche and snowball methods.

  • calculate_savings_goal unknown never probed

    Use when a user asks how much to save each month for a goal, e.g. "how much do I need to save each month to have $50,000 in 5 years?" or "how much a month to reach $1 million in 30 years?". Monthly amount to save to reach a target in a number of years at a yearly rate, counting money already saved. Example: $1,000,000 in 30 years at 8% needs about $671 a month.

  • calculate_fire_number unknown 2h ago

    Use when a user asks when they can retire or how much they need to retire, e.g. "when can I retire if I invest $1,500 a month?", "what is my FIRE number if I spend $40,000 a year?" or "how many years until I can stop working?". Returns the FIRE number (yearly spending / withdrawal rate, 25 times spending at 4%) and, from current savings and a monthly contribution, the months and years to reach it and the age if current_age is given. Uses a real (after inflation) return, 7% by default; same math as the Compound Mint FIRE number calculator.

  • rule_of_72 unknown 2h ago

How long money takes to double at a yearly rate (send annual_rate), or the rate needed to double in a number of years (send years). Gives the Rule of 72 estimate and the exact figure.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id b306c117327e28cd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b306c117327e28cd/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
