- Is frankki-mcp live?
- Yes — it answered the hub's last check (checked 39m ago). It answered 98% of checks over the last 30 days.
- Is frankki-mcp free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does frankki-mcp have?
- 4 tools: address_validate, shipping_quote, pricing_tiers, mcp_health.
- Is frankki-mcp 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.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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.
address_validate reads auth-required never probed
Prüft eine Adresse anhand landesspezifischer Regeln und liefert valid (dasselbe Urteil wie die Adressprüfung von order_send) sowie je Feld, was fehlt, falsch geformt ist oder vom Ort abweicht. Nur eine Prüfung, das Adressbuch bleibt unverändert; Anlegen und Ändern übernimmt address_upsert. EN: Validates an address using country-specific rules and returns valid (the same verdict as the order_send address check) plus, per field, what is missing, malformed or differs from the city. A check only, the address book is left untouched; address_upsert creates and changes addresses.

Ermittelt Preis, Briefformat, Versandart und voraussichtliche Laufzeit für einen geplanten Brief, bevor er versendet wird. Die Schätzung braucht nur Seitenzahl, Land und Versandart. Steht der Brief schon fest, versendet ihn order_send, und order_send mit dryRun:true liefert den genaueren Preis für genau diesen Brief. Der Preis gilt pro Brief und enthält bereits die Mengenstaffel des Partners, falls eine greift (Feld tierId); die Staffelpreise selbst liefert pricing_tiers. Ob es Einschreiben gibt, richtet sich nach dem aktuellen Katalog des Ziellands. einschreiben_einwurf und einschreiben_uebergabe sind deutsche Produkte; die Schweiz hat ch_einschreiben. Für andere Ziele listet ein Standard-shipping_quote für das Land die verfügbaren Versandarten in availableDeliveryTypes, und ein Quote für den gewählten Code liefert dessen Preis. Eine abgelehnte Kombination aus Land und Versandart gilt für genau dieses Paar, ein Katalogstand für genau diesen Stand. Sendungsverfolgung und Einschreiben sind verschiedene Produkte. EN: Determines price, letter format, shipping method and estimated delivery time for a planned letter, before it is sent. The estimate needs only page count, country and delivery type. Once the letter exists, order_send sends it, and order_send with dryRun:true gives the more precise price for that specific letter. The price is per letter and already includes the partner's volume tier where one applies (field tierId); pricing_tiers returns the volume tiers themselves. Registered-mail availability follows the destination's current catalog. The codes einschreiben_einwurf and einschreiben_uebergabe are German products; Switzerland uses ch_einschreiben. For other destinations, a standard shipping_quote for that country lists the available methods in availableDeliveryTypes, and a quote for the chosen code returns its price. A rejected country/method pair gives a verdict for that pair alone. A catalog snapshot gives a verdict for that snapshot alone. Tracked mail and registered mail are distinct products.

Liefert die Staffelpreise (Mengenrabatte) von FrankKi: ab welcher Monatsmenge welcher Beispielpreis pro Brief gilt. Das beantwortet Fragen nach Mengenrabatt, Volumenpreis, Staffelpreis oder Großkundenpreis. Die Beispielpreise gelten für einen einseitigen Standardbrief in Schwarzweiß innerhalb Deutschlands, der echte Preis pro Brief hängt zusätzlich von Seitenzahl, Farbe, Versandart und Zielland ab (den liefert shipping_quote). EN: Returns FrankKi's volume tiers (bulk discounts): from which monthly quantity which example price per letter applies. It answers questions about bulk discounts, volume pricing or enterprise pricing. The example prices are for a one-page black and white standard letter within Germany; the real per-letter price also depends on page count, color, delivery type and destination country (shipping_quote returns that).

Verbindungs- und Einrichtungsprobe: prüft das Partner-Token und die Verarbeitungskette von Anfang bis Ende und meldet unter setup, welche Voraussetzungen für einen echten Versand erfüllt sind (Absender-Profil, AVV, Guthaben, Sandbox, Freigabe, Marke, Briefpapier, Vorlagen) und welcher Schritt als nächster ansteht. Bei einem neuen Konto listet setup.goldenPath die Einrichtungsschritte in Reihenfolge. Jeder Schritt trägt humanSummary (de, en), einen Satz in Alltagssprache für den Menschen; Tool-Namen, nextTool, fixUrl und messageDe/messageEn sind maschinenlesbar. checkRender: true prüft zusätzlich, ob das Rendern gerade funktioniert (Vorschau, Thumbnail), etwa vor dem Bau einer Vorlage, die danach als Bild geprüft wird. Die Antwort kommt in etwa 3 Sekunden: eine Prüfung über ihrem Zeitbudget steht unter degraded und meldet ihren vorsichtigen Standardwert. EN: Connection and setup probe: verifies the partner token and the processing chain end to end and reports under setup which prerequisites for a real send are met (sender profile, data processing agreement, balance, sandbox, approval, brand, letterhead, templates) and which step comes next. On a new account, setup.goldenPath lists the setup steps in order. Every step carries humanSummary (de, en), one sentence in everyday language for the person; tool names, nextTool, fixUrl and messageDe/messageEn are machine-facing. checkRender: true also checks whether rendering works right now (preview, thumbnail), for example before building a template that is then checked as an image. The answer arrives in about 3 seconds: a check over its time budget is listed under degraded and reports its cautious default.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id7cbe6f0a8064cd19.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/7cbe6f0a8064cd19/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
