stablecoin-attestations
https://agentwares-stablecoin.vercel.app
Registry code: 0499b024d9aaa097
Issuer reserve attestations parsed to JSON. 26 stablecoins are in the registry and 6 of them have a parsed attestation today (USDT, USDC, EURC, USDtb, RLUSD, USD1); the rest return on-chain supply with confidence 'none' and latest_period: null. Start with stablecoin_list_issuers (free) to pick a symbol, then stablecoin_reserves({symbol}) — $0.02 per call against a prepaid balance (Authorization: Bearer <key>), or sample=true for a free example that needs no key. No key yet? POST /v1/keys with no auth for one, then POST its fund_url to get a Stripe Checkout URL, or fund it in USDC over x402;…

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.
stablecoin_list_issuers reads open 17h ago
Free. Lists every issuer in the registry with symbol, issuer, attestation type, attestor, cadence, source_url and which months are parsed. Call it first to pick a symbol for stablecoin_reserves.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {}, "additionalProperties": false }arguments 6 linesstablecoin_reserves reads unknown never probed
Latest parsed reserve attestation for one stablecoin issuer as JSON: as_of date, total reserves, composition by asset category, attestor, source_url, current on-chain supply (DefiLlama) and the reserve ratio. Use it when an agent needs machine-readable backing data instead of reading the issuer's PDF. Pass symbol (USDC, USDT, ...) or issuer; period=YYYY-MM selects an earlier month. Issuers without a third-party attestation return supply only with confidence 'none'. Paid: $0.02 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.

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 id0499b024d9aaa097.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/0499b024d9aaa097/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.
