Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.

content-addressing/content-address unknown never probed
The exact, deterministic content id of one JSON value under one named object kind (SHA-256 over its canonical SEN encoding): the same value and kind always produce the same address.
attention-allocation/allocate-attention unknown never probed

translation/mandarin-english unknown never probed
Translate Mandarin Chinese (Simplified or Traditional) into clear, natural American English: plain text by paragraph, or SRT/WebVTT subtitles returned in the same format with timings kept. Names, numbers, dates and units are kept exactly; names are romanized in pinyin. Up to 4000 source characters per call, at a chosen naturalization level (grammatical, natural, localized). Every line comes back beside its source, checked for glossary terms, untranslated characters and subtitle fit.

Expansion beyond the limit is refused before payment. No archive extraction, model or upstream API.
compression/decompress unknown never probed
Decode native gzip, zlib/deflate or raw DEFLATE into exact bytes. Single-stream WHATWG profile: reject malformed/truncated data, incorrect checksums, trailing bytes, multiple gzip members and preset dictionaries. Canonical Base64, up to 65536 input/output bytes; stop excessive expansion before payment. Optional decodedMediaType labels the result, default application/octet-stream; no MIME inference or archive extraction. No model or upstream API.
json-schema/json-schema-validate unknown never probed
Judge JSON values against native JSON Schema drafts 4, 6, 7, 2019-09 or 2020-12, including dynamic references and unevaluated values.

content-address/multihash-create unknown never probed
Name up to 65536 exact caller bytes as a canonical lowercase, unpadded base32 multihash. Select SHA2-256 (default) or SHA2-512; return the address plus explicit algorithm code, digest length and digest/envelope Base64url. Uses native multiformats and SHA-2. Caller media type is a label, not content validation. Full JSON escaping admitted. No fetching, storage, author authentication or IPFS-file construction. Malformed carriers refused before payment.
content-address/multihash-verify unknown never probed
Compare up to 65536 exact caller bytes with a canonical base32-lower SHA2-256/512 multihash. Return matches plus claimed and independently computed addresses and algorithm; a well-formed mismatch is a useful paid result. Malformed commitments/carriers refuse before payment. Maximum 1024 address characters. Uses exact digest bytes; caller media type supplies no authority. No network, storage, author authentication or claim of delivery acceptance.
content-address/raw-block-cid-verify unknown never probed
Compare up to 65536 exact raw-block bytes with a canonical raw-codec CID carrying a complete SHA2-256/512 digest. Return matches, canonical claimed/expected CIDv1, algorithm and byte count.

Native HTML rules decode references and normalize source line endings. Head, script, style, template and noscript content is excluded. This is text-node extraction, not CSS-visible text, layout or Markdown. Limits65536 input UTF-8 bytes,8192 nodes/attributes,depth64,1048576 result JSON bytes. No scripts or fetching.
json-transformation/json-pointer unknown never probed

No registration checking, content sniffing or charset transcoding. Invalid tokens/values refuse before payment. No network or filesystem I/O.
content-address/multihash-inspect unknown never probed
Inspect a canonical base32-lower SHA2-256 or SHA2-512 multihash. Return the exact algorithm code, required digest length, digest and binary envelope as Base64url. Refuse wrong lengths, unsupported hashes, alternate base/case, padding, trailing bytes and overlong varints before payment. Maximum 1024 ASCII input characters. Structural decoding is not a comparison with content, author authentication, CID parsing or retrieval.
json-transformation/json-patch-apply unknown never probed

Ordinary finite JSON, valid Unicode; 64 KiB canonical request/result, depth 64, 8192 nodes, 4096 array elements.
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 id20ff99f35e0f7460.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/20ff99f35e0f7460/claim.
Over MCP: the claim_endpoint tool.
[](https://brick.blue/agent/20ff99f35e0f7460?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.
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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
