The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 6 tools

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.

  • get_graph open 54m ago

    Summarize the CWI catalog knowledge graph (node/edge counts, types, sample nodes). For the full graph, fetch GET /graph.json.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • search_catalog unknown never probed

    Search the CWI placement catalog (That Boy Hi Hat + roster) by keywords. Same scored engine as GET /query: title matches weigh 3x, genre 2x, mood 1x. Returns top 5 tracks with Spotify URLs and matched terms.

    mcp-tool

    {
  "type": "object",
  "required": [
    "q"
  ],
  "properties": {
    "q": {
      "type": "string",
      "description": "Search keywords, e.g. \"cyberpunk rap\" or \"dark cinematic\". Truncated at 500 characters."
    }
  }
}
    arguments 12 lines
  • get_track unknown 54m ago

    Look up one catalog track by title or Spotify ID/URL. Returns title, artist, Spotify URL, genres, and moods.

    mcp-tool

    {
  "type": "object",
  "required": [
    "id_or_title"
  ],
  "properties": {
    "id_or_title": {
      "type": "string",
      "description": "Track title (exact or partial) or a Spotify track ID / open.spotify.com URL."
    }
  }
}
    arguments 12 lines
  • get_artist unknown 54m ago

    Look up an artist by name. Returns the artist and their tracks in the catalog with Spotify URLs.

    mcp-tool

    {
  "type": "object",
  "required": [
    "name"
  ],
  "properties": {
    "name": {
      "type": "string",
      "description": "Artist name, e.g. \"That Boy Hi Hat\"."
    }
  }
}
    arguments 12 lines
  • sync_search unknown never probed

    Search the CWI sync catalog (23 tracks with editorial sonic descriptors: moods, energy words, instrumentation, scenes, use-cases, lyrical themes) for music-supervision queries like "fight scene" or "neon city". Descriptors are editorial (curated by CWI Sync); BPM values are estimates, not audio analysis.

    mcp-tool

    {
  "type": "object",
  "required": [
    "q"
  ],
  "properties": {
    "q": {
      "type": "string",
      "description": "Sync query, e.g. \"club scene\" or \"dark aggressive\". Truncated at 500 characters."
    }
  }
}
    arguments 12 lines
  • semantic_search unknown never probed

    Semantic search over the CWI catalog embedding matrix: cosine similarity against 384-dim bge-small-en-v1.5 vectors (55 tracks). The query is embedded at request time with Workers AI @cf/baai/bge-small-en-v1.5 — the same model that produced the matrix, so catalog and query vectors are directly cosine-comparable. No inference needed on your side; just call this tool. FALLBACK (documented, never silent): if the Workers AI [ai] binding is unavailable at runtime, the tool DEGRADES to keyword scoring over the matrix text fields and says so in its response (method "fallback:keyword", plus a fallback_note). Fallback scores are keyword weights (title 3x, genre/descriptor 2x, mood 1x) — they are NOT cosine similarity and are never presented as semantic scores.

    },

_ 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.

  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 af2ff70b4ef4c448.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/af2ff70b4ef4c448/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.

_ 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
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.
