Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

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.
find_subreddits unknown 1h ago
Use this when someone asks which subreddits or Reddit communities fit a product, brand or niche, or where on Reddit AI answers look for recommendations in a category. Takes a short description such as "AI writing tool for marketers" and returns up to 10 matching subreddits, closest match first, with how often AI answers cited each, members and a link to each subreddit's data page. Only subreddits in CommunityMentions' data (cited 50+ times or with 50+ verified comments placed) are included; health, legal-help and adult communities are left out.

Use this when someone asks how often AI answers cite a specific subreddit, which of its threads get cited, or whether it matters for being recommended by ChatGPT, Perplexity or Gemini. Takes a subreddit name such as "SaaS" or "r/marketing" and returns its AI citations by engine, the kinds of questions those answers were about, its most-cited threads and its member count.

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 ide776f341620ee7e6.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/e776f341620ee7e6/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.
