Registry code: a7d50b931130b873

api record

Truvon: a record of 3.7 million U.S. businesses, each fact with its source and date, for agents acting for a person. It tells you which business is open, which phone and address its sources agree on, what it offers in its own words, and how to act.

How to use it: find_local_businesses with the service in a few plain words ("furnace repair", "water heater leak", "bbq catering for 12") and the place as "Town, ST"; put a specific time in open_at (a range like "this week" has no field: leave it out and judge from the hours shown) and requirements in the filters, not in need. Or…

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 11 tools
11 never probed 0 of 11 classified

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.

    Check up to 10 businesses you found elsewhere (maps, web, a link) before you give your user a phone or send them somewhere: open or closed with dated evidence, the phone its sources agree on, how to act. Send the name plus phone, website or address, and the town. With the need, you also get two listed businesses that fit it that you did not send. One not found is reported as not in Truvon.

  • find_local_businesses unknown 4h ago

    Start here. Find businesses that fit a need near a place. Give the service in a few plain words ("furnace repair", "water heater leak"), not the user's sentence; timing goes in open_at. Each result says why it fits, its hours and whether it is open right now (by its stated hours at its local time; "open:" is whether it is in business), the phone, and how to act, and the response ends with your next step. Five results by default; ask for more with limit, and add max_minutes to stay close.

  • connect_truvon unknown never probed

    When your app has not signed in to Truvon itself: get a link for your user to open and a connection code for you. One tap on the link (no account) and the reporting tools accept connection in this conversation. Searching needs none of this.

_ 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 a7d50b931130b873.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a7d50b931130b873/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
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.
