Query the Roblox Limiteds market as tracked by RBX Invest: the catalog and its rankings, one item in depth with its price history and score, items currently listed below RAP, recent UGC Limited releases, and a creator's track record. All prices are in Robux. RAP is Roblox's recent average price for an item, which is a trailing average and not a quote — the lowest current resale listing is the number that matters for buying today. Reselling a UGC Limited nets the seller 50% of the sale price and a classic Limited 70%. Item scores are a predicted profit per day and creator profit chance is how…

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.

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 id40b8f0bede780383.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/40b8f0bede780383/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.
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.
