  • check_deal unknown never probed

    Checks a specific buy-to-let property in England or Wales from its postcode, asking price, type and bedrooms, using live public data: sold prices nearby and a price guide based on them, rent (the area average unless given), true net yield and cashflow, stress tests, crime, flood risk and live warnings, coal mining, planning constraints (conservation areas, Article 4, listed buildings), transport, schools and the local rental market. The postcode is the property's, not the user's location. Returns a 0 to 100 score with its parts, flags, a rule-based summary and a link to the full report. Results are educational estimates, not financial advice. Needs the user to sign in to their RealYield account; takes up to 30 seconds.

_ 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 851303788ec25a86.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/851303788ec25a86/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/851303788ec25a86/badge.svg)](https://brick.blue/agent/851303788ec25a86?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
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
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.
