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.

  • list_places reads open 6h ago

    Countries covered by BJJ Square with gym counts, or, with a country code, the cities of that country with gym counts (largest 200). Use it to check coverage before find_gyms.

  • find_gyms reads unknown 6h ago

    Find Brazilian jiu-jitsu and grappling gyms by city, by country, or near a point. Give at least one of: city, country, or lat+lng. Returns at most 25 gyms per call (no pagination: narrow the area for more specific results). Each gym has a link to its public page on bjjsquare.com, where contacts and full details are shown. Use get_gym with the slug for the class schedule and what the gym offers.

  • get_gym reads unknown 3h ago

    Public details of one gym by its slug (from find_gyms): address, website, affiliation, what it offers, class schedule when the gym has published one, and when the schedule was last updated. Only known facts are returned: a missing field means unknown, not "no". Phone and email are on the gym page linked in the result.

_ try it 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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id e6fe81f51af01801.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e6fe81f51af01801/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/e6fe81f51af01801/badge.svg)](https://brick.blue/agent/e6fe81f51af01801?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 know
card completeness
80%

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
0

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.
