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.

  • search_properties reads unknown never probed

    Use this when the user wants to find, compare, or shortlist Spanish properties (flat, house, office, land) for buy/rent using location, budget, rooms, floor, and lifestyle preferences (e.g. nature, views, natural light). LLM must send either `city` (single municipality) or `locations[]` (multiple municipalities/towns, recommended 3-5, hard max 5). If the user mentions neighborhoods, districts, comarcas, or regions, send those in `location_hints[]` (soft preference for reranking), not in `city`. `query_text` is context only and never a substitute for structured constraints. Treat `min_floor` and `exclude_ground_floor` as apartment-style filters: only set them when the user explicitly asks for upper-floor/non-ground-floor units, not as a proxy for generic brightness or light. Do not set `sources` unless the user explicitly asks for specific portals. Returns normalized listings with portal links, prices, photos, explainability (`why_matched`), presentation cards, and execution diagnostics including per-location and per-source coverage.

_ 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 c419c6b0d6108cc8.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c419c6b0d6108cc8/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.

card completeness
50%

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.
