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.

search_properties unknown 38m ago

Search normalized U.S. property records (owner, structural attributes, tax assessments, tax + sale history) by location. Pin a location one of three ways: a full address, a city+state(+zipCode), or a latitude+longitude point with a radius (miles). All other parameters narrow the result set. Records are cached 24h upstream, so meta.cached may be true on repeat queries.

get_property unknown never probed

Full detail for a single property record, keyed by its RentCast id (the same id returned on every search_properties, avm_value, avm_rent, and listings record). Returns 404 if no property matches the id. Cached 24h upstream.

search_sale_listings unknown never probed

Return a page of for-sale listings (list price, status, days on market, MLS name/number, listing agent + office contact, and price/status history) for a location. Same location-pinning rules as search_properties (address, city+state(+zipCode), or latitude+longitude+radius). Each record is tagged listingKind:"sale". Listings move faster than records, so these are cached only 30 minutes upstream.

_ try it 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.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/ca93b655081bf5da/badge.svg)](https://brick.blue/agent/ca93b655081bf5da)

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.

_ how we know

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

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.
