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.

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.

Returns the top 10 Urantia paragraphs whose embeddings are nearest to the Bible chunk that contains this verse — the reverse of `include_bible_parallels` on the UB side. Pre-computed at seed time with text-embedding-3-large (3072-d) cosine similarity. Each result carries a similarity score (0..1) and rank (1..10). These are *semantic* parallels, not curated. Treat results as starting points for further reading, not as authoritative parallels.

Example: \"Matt\"" } } }arguments 27 linesbible.search.semantic unknown 6h ago
Free-form natural-language search across all Bible chunks, ranked by cosine similarity. Each result includes the top-N pre-computed Urantia paragraphs related to that chunk via `bible_parallels` (direction=bible_to_ub). One query surfaces both Bible matches and the relevant UB content. Optional filters: `canon` (`ot`, `deuterocanon`, `nt`) and `book_code`. Set `urantia_parallel_limit` to 0 to suppress the UB attachment. Requires OPENAI_API_KEY.

Example: \"Matt\" or \"Matthew\"" }, "urantia_parallel_limit": { "type": "integer", "default": 3, "maximum": 10, "minimum": 0, "description": "How many UB paragraphs to attach per Bible result (0-10, default 3). 0 disables." } } }arguments 48 lines
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.
[](https://brick.blue/agent/a18ff091cf46ddab)
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
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.
