Stockmarket Loans (stockmarket.loans) answers questions about what it costs to borrow against a stock portfolio: each US broker's published margin rate schedule, a side-by-side ranking at any loan balance, and the interest cost of a balance over a number of months. Every rate is copied from the broker's own margin rate page or fee schedule (source URL and the broker's printed date on each result); rates were last checked against those pages on 2026-10-24. Interactive Brokers rates follow its USD benchmark plus the printed spread and update when a newer benchmark reading is available. Results…

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.

  • compare_brokers unknown 48m ago

    Every compared broker's published annual margin rate on one loan balance, ranked from lowest to highest (ties shared), with the tier that applies, the yearly interest at that rate, schedule dates and source links. Brokers that print no rate at that balance are listed separately with the reason.

  • borrowing_cost unknown 48m ago

    What a margin loan costs over a number of months at every compared broker's published rate, as the site's margin interest calculator works it: rate, interest per month, total over the period and the extra cost versus the lowest rate, simple interest on a flat balance. Optionally adds a rate you were quoted (an SBLOC offer or a negotiated margin rate) or narrows the table to one broker.

  • get_margin_rates unknown 48m ago

    One broker's published margin rate schedule: every balance tier with its annual rate and the broker's own wording for how it is set, the base rate and its date, whether tiers blend, maintenance and minimum-equity notes, the schedule date, our check date and the broker's source URL. A family name like "Interactive Brokers" returns each of its plans.

      "type": "object",

        "broker"
      ],

          "type": "string",
          "maxLength": 60,
          "minLength": 2,
          "description": "Broker name, e.g. \"Schwab\", \"Fidelity\", \"Interactive Brokers\", \"Robinhood\"."
        }

_ 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 53c4e61fb533810a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/53c4e61fb533810a/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.
