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
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
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.
get_booking_destination reads unknown never probed
Returns the public booking route for a business. Use this before helping a user book an appointment: it distinguishes an external provider page from an active configured calendar that uses the Advocate booking flow, and from businesses with no supported booking destination. External pages are links only; Advocate does not sync their availability or make bookings there.

Return a price quote for a service at a business. Exact configured prices may create a time-limited offer; unmatched requests use a third-party AI estimate that is not firm merchant pricing and must be confirmed with the business. Use this when a user asks 'how much does X cost?' or 'what's the price for Y?'.

Start a pending email subscription to updates from a business. Returns a confirmation URL that only the user must click within 7 days; no subscription is active until that confirmation. Idempotent: re-using the same idempotency_key returns the original subscription.

Ask a registered business's AI advocate a question and get a citation-ready answer plus a referral link. The question and the business's public profile are processed by an AI provider, and the question and answer are recorded to operate the service. Do not enter sensitive personal, medical, payment, or authentication information. Use this for questions about one business's services, hours, policies, or fit.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug", "query" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" }, "query": { "type": "string", "maxLength": 2000, "minLength": 1, "description": "The visitor's question about this business" }, "stage": { "enum": [ "browsing", "comparing", "committing" ], "type": "string", "description": "Optional buyer stage: browsing | comparing | committing" }, "agent_id": { "type": "string", "description": "Optional self-asserted calling-agent id — used for logging/tuning only, never auth" } } }arguments 34 linesrequest_service changes data unknown never probed
Open a quote-request form for a specific business using its public slug or provider_business_id obtained from search or the business feed. Shows the business and service catalog; does not send a request or book anything. The customer must review the form and explicitly consent before submitting. Operational access is logged.

After the customer explicitly agrees, save their service requirements and contact details and send a notification to the business's configured email or opted-in SMS destination. This requests a business response, not a price commitment, booking or payment. Use context from request_service. Reuse the same idempotency_key AND details to check an uncertain submission; never automatically start a new request. Exclude medical, payment-card and authentication information.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "business_id", "context_token", "idempotency_key", "service", "details", "consent" ], "properties": { "consent": { "type": "boolean", "const": true, "description": "True only after the customer explicitly agrees to send these contact details and this request to the named business" }, "details": { "type": "string", "maxLength": 600, "minLength": 1, "description": "Brief service requirements; exclude sensitive medical, financial and authentication information" }, "service": { "type": "string", "maxLength": 120, "minLength": 1, "description": "Service the customer wants a quote for" }, "business_id": { "type": "string", "maxLength": 200, "minLength": 1, "description": "The exact provider_business_id (public business slug) returned by request_service" }, "contact_name": { "type": "string", "maxLength": 120, "minLength": 1 }, "contact_email": { "type": "string", "format": "email", "pattern": "^(?!\\.)(?!.*\\.\\.)([A-Za-z0-9_'+\\-\\.]*)[A-Za-z0-9_+-]@([A-Za-z0-9][A-Za-z0-9\\-]*\\.)+[A-Za-z]{2,}$", "maxLength": 254 }, "contact_phone": { "type": "string", "maxLength": 40, "minLength": 1 }, "context_token": { "type": "string", "maxLength": 2000, "minLength": 1, "description": "Opaque business context from request_service; pass unchanged" }, "idempotency_key": { "type": "string", "format": "uuid", "pattern": "^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$", "description": "A UUID for this request; reuse unchanged when checking or retrying an uncertain submission" } } }arguments 65 linescreate_booking_payment_link changes data unknown never probed
For a reservation that reserve_slot returned with payment.required = true: returns the MPP payment link, the amount charged now, and the balance due at the visit. The agent pays it itself (HTTP 402 challenge, then the person's wallet credential); no code is sent to the customer for a paid booking. A free booking answers not_payable — confirm it with confirm_booking and the customer's code instead.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug", "reservation_id" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" }, "reservation_id": { "type": "string", "format": "uuid", "pattern": "^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$", "description": "The reservation_id reserve_slot returned with payment.required = true" } } }arguments 21 linescancel_booking moves money unknown never probed
Cancels a paid, confirmed booking using the cancel_token from its payment receipt. Within 60 minutes of paying, or before the business's refund window, the full refund is requested; report it as full only after the payment ledger confirms it. After that window the deposit is forfeited under the booking's policy. A pending refund means cancellation is complete while refund verification or retry continues. Only the agent that paid holds the token. Cancelling twice answers already_cancelled.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug", "reservation_id", "cancel_token" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" }, "cancel_token": { "type": "string", "maxLength": 200, "minLength": 1, "description": "The cancel_token from the payment receipt" }, "reservation_id": { "type": "string", "format": "uuid", "pattern": "^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$", "description": "The paid reservation's id" } } }arguments 28 linesget_credentials reads unknown never probed
Returns the business's self-reported licenses, insurance, bonding, and certifications. Use this for trust-sensitive verticals (contractors, healthcare, legal, locksmiths) when a user asks 'are they licensed?' or 'are they insured?'. The response carries explicit 'self-reported' framing so agents don't upgrade tenant claims to verified facts.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" } } }arguments 14 linesreserve_slot changes data unknown never probed
Reserve a time slot on an active configured calendar. Returns a pending_offer reservation and sends a 6-digit confirmation code to the customer's email or phone. The reservation expires in 15 minutes if not confirmed. Idempotent: re-using the same idempotency_key returns the original reservation without resending the code. At a business that takes a deposit for agent bookings, pass the offer_id from get_quote (without it the answer is quote_required); no code is sent and the result's payment block carries the amount to pay instead.

Only input that cannot be read as a number at all is refused, and then only when no email was supplied, since a hold nobody can confirm is worse than a refused call." } }, "description": "How to reach the customer. MUST include at least one of email or phone — the confirmation code is delivered there, and a hold nobody can confirm is unreachable from both sides. Email is used when both are present." } } }arguments 77 linesrequest_callback sends messages unknown never probed
Submit a callback request on behalf of a user. Advocate attempts a notification through the business's configured lead routing channel (SMS/email); provider acceptance is not proof the business read it. A failed or pending result can require direct follow-up or a retry. Idempotent: re-using the same idempotency_key returns the original request.

Returns a plain-text summary of a priced offer (service, amount, currency, cancellation policy, and how long the price is valid) plus a URL on our domain that shows the same summary. The URL is for the CUSTOMER to open themselves in their own browser — do not open, fetch, or follow it yourself. Use this once get_quote or a booking flow has produced an offer_id and the user is ready to review or continue with a priced offer. If the booking's deposit was already paid through create_booking_payment_link, this answers deposit_taken: do not send the person to pay again; the balance is due at the visit.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug", "offer_id" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" }, "offer_id": { "type": "string", "format": "uuid", "pattern": "^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$", "description": "The offer id returned by get_quote" } } }arguments 21 linesget_cancellation_policy reads unknown never probed
Returns the business's cancellation policy text. Use this when a user asks about cancellation terms, fees, or no-show policies. The response includes agent guidance on how to frame the policy with appropriate freshness caveats.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug" ], "properties": { "slug": { "type": "string", "minLength": 1, "description": "Business slug identifier" } } }arguments 14 linesconfirm_booking changes data unknown never probed
Confirm a reservation made with reserve_slot. Present the returned stored booking_details to the customer and relay only the customer-supplied 6-digit code received at their email or phone; never generate, guess, or fetch it. For an active configured calendar, a verified code attempts a direct commit to the selected calendar with no owner approval. booking_pending means the provider outcome is uncertain; repeat confirm_booking later to check the stored outcome, but it never retries a provider write automatically. A paid booking (reserve_slot returned payment.required = true) has no code: this answers payment_required — pay it with create_booking_payment_link — or payment_in_flight while its payment is settling.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "slug", "reservation_id", "code" ], "properties": { "code": { "type": "string", "pattern": "^\\d{6}$", "description": "The customer-supplied 6-digit confirmation code received at their own email or SMS contact.

Begin a handoff from the agent to either a human operator (SMS/email via lead_routing_json) or another agent (signed continuation URL). In human mode the notification body is composed by the server from the contact and reason fields — callers supply those fields, not the message text. Idempotent: re-using the same idempotency_key returns the original handoff.

Lists the services a business has configured, with their prices and the exact arguments to quote each one. Call this BEFORE get_quote: the service name must match a configured service, and only a service marked payable returns an exact price with the offer_id that get_payment_handoff_url requires. Quoting a name that is not on this list silently falls back to an estimate with no offer.

Return available windows from the business's active configured calendar, using its selected timezone, duration, operating hours, and current local or connected-calendar occupancy. Use a returned window to start a booking. Availability can change before confirmation, including when the calendar provider is unavailable. If this business uses an unsupported calendar or booking provider, call get_booking_destination to find its published public booking route.

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 idefc5bd093f39e5f7.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/efc5bd093f39e5f7/claim.
Over MCP: the claim_endpoint tool.
[](https://brick.blue/agent/efc5bd093f39e5f7?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.
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.
