Verified XRP Ledger answers with proof. Free tools: list_services, get_sample, learn_about_bruk. Paid tools use x402: call once without payment to receive the payment requirements, then retry with params._meta['x402/payment'].

- Is bruk live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is bruk free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does bruk have?
- 9 tools: list_services, get_sample, learn_about_bruk, send_check, ledger_pulse, large_payments, payment_watch, payment_check, ….
- Is bruk safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid
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.
send_check 0.00385 USDC paid never probed
Pre-send check for an XRP Ledger payment: whether the destination is activated, requires a destination tag, blocks or pre-approves senders, can hold the token (trust line, limit, freeze, issuer approval), is blackholed, and whether the source can afford it. Returns ok_to_send, send_with_caution, or will_fail with reasons. Useful before any irreversible XRP Ledger payment. Price about $0.005 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.

XRP Ledger network health right now: latest validated ledger, close time, transactions and payments in it, fee levels, load, and rolling averages cross-checked against a direct ledger read. Useful before submitting XRP Ledger transactions or when reporting current network conditions. Price about $0.001 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 lineslarge_payments 0.0155 USDC paid never probed
Lists large XRP Ledger payments (50,000+ XRP or major stablecoins) in a recent window of up to 120 minutes, each independently re-checked on the ledger, with an explicit note when the window is not fully covered. Useful for market and liquidity monitoring. Price about $0.02 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.

Payment arrival alert: watches an XRP Ledger address for up to 24 hours and POSTs a signed webhook when a matching payment is final (validated, tesSUCCESS, delivered amount checked), or a watch.expired event if none arrives. Payments that land during restarts are still caught. Useful when waiting on an incoming payment without polling. Price about $0.05 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.

Verifies that an XRP Ledger payment settled as expected: validation, result code, destination, destination tag, currency, issuer, and the amount actually delivered, which exposes partial-payment tricks. Useful when confirming that a customer or counterparty really paid. Price about $0.01 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.

Checks whether an XRP Ledger token issuer is who it claims to be: two-way domain verification (on-ledger Domain field against the domain's xrp-ledger.toml), tokens issued and outstanding, and control flags such as freeze, clawback, blackholed, and multisign. Useful before accepting or holding a token. Price about $0.01 per call via x402 (USDC on Base, or XRP / RLUSD on the XRP Ledger). Without a payment the tool returns the x402 payment requirements; bad input and ledger outages are never charged.
{ "type": "object", "required": [ "account" ], "properties": { "account": { "type": "string", "description": "XRP Ledger r-address" } }, "additionalProperties": false }arguments 13 lineslearn_about_bruk open 1h ago

{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linesget_sample unknown 1h ago
Free. Returns a recent real answer from a Brük service (cached up to 5 minutes) so you can see the format before paying.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id2bd03351968af33d.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/2bd03351968af33d/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
