api record

401k.loans runs calculators for the cost of borrowing from or withdrawing from a 401(k). These tools run the same arithmetic as the calculators on the site (same formulas, same defaults) on the numbers you pass.

calculate_401k_loan_cost: payment, interest, growth gap and the leaving-your-job bill for a plan loan. compare_401k_loan_alternatives: the same cash raised four ways (401(k) loan, hardship withdrawal, personal loan, HELOC). calculate_401k_early_withdrawal: tax, the 10% additional tax and withholding on a withdrawal.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 3 tools
3 never probed 0 of 3 classified

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_401k_early_withdrawal unknown never probed

    Runs the 401k.loans early withdrawal calculator for a cash-out or hardship withdrawal: amount taken out (or the gross needed to net a target), income tax at your marginal rates, the 10% additional tax, what you keep, what the plan withholds up front (20% mandatory, or 10% default for hardship), the check amount, and the balance due or refund at filing.

  • calculate_401k_loan_cost unknown 51m ago

    Runs the 401k.loans true-cost calculator: payment per paycheck and number of payments, total repaid and interest, pre-tax pay needed per payment, tax later on the interest, the 401(k) balance at payoff with and without the loan (growth gap) and that gap at 65, the legal and usual plan borrowing limits, and, if you might leave the job, the balance owed then plus the tax and 10% additional tax if it is not repaid or rolled over.

  • compare_401k_loan_alternatives unknown 51m ago

    Prices four ways to raise the same cash with the 401k.loans comparison tool: 401(k) loan, hardship withdrawal (grossed up for tax and the 10% additional tax), personal loan (rate plus origination fee) and HELOC. For each: amount taken out, monthly payment, money gone for good (interest to others, fees, tax, penalty), interest paid back to yourself, how much smaller the 401(k) is at term end and at 65, and whether it is allowed.

_ 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 6afd93505a78b0c8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6afd93505a78b0c8/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
70%

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.
