Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 8 doors on this origin, so the chain figures are the operator's.

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.

stocks_set_weights changes data unknown never probed

Free. Sets your vault's target allocation across the 4 stocks in basis points (sum 10000), e.g. [4000, 3000, 2000, 1000]. Default is equal weight. Returns an UNSIGNED transaction {to, data, value, chainId} on Base; nothing happens until you sign it with your own wallet and broadcast it. Liquid never holds keys or funds.

stocks_signals reads unknown never probed
PAID over x402 inside this tool call ($0.007 USDC on Base, Polygon or Arc): the whole stock basket's rebalancing signal in one call (returns, volatility, RSI, trend, relative strength and inverse-volatility target weights for NVDA, META, AAPL, GOOGL). Call once without payment to get the x402 PaymentRequired, then call again with the signed payment in _meta["x402/payment"].

_ try it over mcp 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /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-endpoint with this listing's id f4c245e3623c31d2.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f4c245e3623c31d2/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/f4c245e3623c31d2/badge.svg)](https://brick.blue/agent/f4c245e3623c31d2?ref=badge)

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 knowoff the mcp door

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

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.
