api record

Card Mailer prints 5x7 photo postcards (no envelope) and mails them by USPS First-Class to US addresses. Typical flow: import_address_list -> design_card -> quote_mailing -> create_mailing (returns a link where the user pays on cards.onmax.me) -> get_mailing_status. Nothing is printed or charged until the user pays on that page. US addresses only. For holiday, thank-you and other personal or client greeting cards; not for e-cards, email, or advertising mail.

_ is it live, free and safe measured by this hub
Is card-mailer live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is card-mailer free to use?

What tools does card-mailer have?
6 tools: design_card, quote_mailing, get_mailing_status, import_address_list, fix_address, create_mailing.
Is card-mailer safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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 6 tools
6 never probed 0 of 6 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.

  • design_card unknown never probed

    Use this to create or edit the printed 5x7 postcard: a greeting on the front over or under the photo, and a message and sign-off on the back. Pass the photo the user attached as photo, or a public https image URL as photo_url; the image is downloaded and stored on cards.onmax.me. Without a photo the front is the greeting on a solid color. Pass design_id to edit a design: given fields replace the old values and omitted fields keep them. Use the message the user wrote or approved, up to 500 characters. Places the user's photo and text in a print template; does not generate images.

  • quote_mailing unknown 1h ago

    Use this when the user asks what mailing a card to an imported list costs or when it will arrive. Returns the price per card (First-Class postage included), the total for the ready recipients, the send date and the expected arrival window. If the cards must arrive by a date, pass arrive_by; the result gives the latest safe send date and whether that date can be met. Does not create an order or charge anything.

  • get_mailing_status unknown 1h ago

    Use this when the user asks whether a Card Mailer order was paid, printed, mailed or delivered. Takes the mailing_id returned by create_mailing (also the last part of the order link). Returns the status, send date, expected arrival and per-recipient counts. Does not change the order or track other USPS mail.

  • import_address_list unknown never probed

    Use this when the user wants to mail printed cards to people at US postal addresses and gives the addresses as pasted text, a CSV, or an .xlsx spreadsheet. Reads names and addresses, checks each against USPS data, and saves them as a recipient list. Returns a list_id, how many rows are ready, and the problem for each row that needs fixing. Up to 300 recipients; pass list_id to append rows to an existing list. US addresses only. Not for e-cards or email, addresses outside the US, or advertising mail to purchased or rented lists.

  • fix_address unknown never probed

    Use this to correct or remove one recipient in a list from import_address_list, by row number. Given fields replace the stored values and omitted fields keep theirs; if the row's problem says it could not be read, pass name, line1, city, state and zip together. Re-checks the address with USPS data. remove: true takes the recipient out of the mailing. Rows in a list that belongs to a paid order cannot be changed.

  • create_mailing unknown never probed

    Use this when the user has seen the card and the quote and says they want to order. Creates an unpaid order for the ready recipients in list_id with design_id and returns a link to cards.onmax.me, where the user reviews the recipients and pays. Nothing is printed, mailed or charged until the user pays on that page. Recipients that still need fixing are left out. Each call creates a separate order link, so call it once per order. Optional sender is printed as the US return address.

_ 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 e2f76e5590ea1466.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e2f76e5590ea1466/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.

_ 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.
