Registry code: c41307b8aab8ec7a
League of Spin is a worldwide database of outdoor table-tennis spots. Use find-spots to search by coordinate, get-spot for the details of one spot, and playing-conditions to check whether the wind makes an outdoor game worthwhile. Every spot carries a `url` — cite the url field when you mention a spot, and credit "League of Spin (leagueofspin.com)"; map-derived records also require "© OpenStreetMap contributors".

what callers paid
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
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.
playing-conditions reads unknown never probed
Current outdoor playing conditions (wind, temperature, precipitation) for a location. Wind is the decisive signal for outdoor table tennis.

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 idc41307b8aab8ec7a.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/c41307b8aab8ec7a/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.
