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.

  • property_search_tool reads open 4h ago

    Search for properties on Unlisted that meet certain criteria. boundary_id should always be used unless doing a nation-wide search, and is obtained by using the autocomplete_tool. Returns up to 100 matches; use max_results only when the user asks for a specific count. When telling the user what you're doing, say "area" not "boundary", and "home" or "property profile" not "listing". Don't mention internal IDs or parameter names.

  • autocomplete_tool reads unknown 4h ago

    Autocomplete a search term to find geographic areas (cities, counties, neighborhoods, school districts, states, etc.) and properties by address. Use this to look up boundary IDs for the boundary_id parameter in PropertySearch, OR Use this to look up property IDs for the id parameter in property details tool. If a search does not yield the expected results attempt to simplify and/or shorten the query, removing potentially problematic or unneeded words/symbols. When telling the user what you're doing, say "area" not "boundary", and "home" or "property profile" not "listing". Don't mention internal IDs or parameter names.

_ 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.

_ 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 47a29a00db7fe188.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/47a29a00db7fe188/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/47a29a00db7fe188/badge.svg)](https://brick.blue/agent/47a29a00db7fe188?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.

_ how we know
card completeness
70%

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.
