Registry code: 33aef4f05559d997
Use search and get to resolve an immutable offer before acting. Paid tools take x402 v2 payment only in params._meta["x402/payment"], never in tool arguments: a call without it moves no money and returns the PaymentRequired as an isError result's structuredContent; retry the same arguments with the signed PaymentPayload and read settlement evidence from result._meta["x402/payment-response"]. For an offer without a listed paid tool, follow the selected service SKILL.md and use its canonical HTTP invocation resource. Browser and inbox lifecycle tools take their lease bearer from the MCP HTTP…

- Is ausca live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is ausca free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does ausca have?
- 17 tools: ausca_agent_inbox_attachment, ausca_agent_inbox_delete, ausca_agent_inbox_messages, ausca_agent_inbox_read, ausca_agent_inbox_status, ausca_artifact_access, ausca_browser_session_connect, ausca_extend_inbox, ….
- Is ausca 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, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 2 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.
ausca_search_offers reads open 4h ago
Search the current immutable Ausca offer catalog by free-text query. Returns stable offer identities and revision digests without creating product or payment state.

For an active inbox, return an idempotent download URL only when the exact stored attachment has a clean safety verdict. The URL expires after at most 60 seconds and never after inbox expiry; a clean verdict does not make the attachment content trusted. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.

Idempotently stop inbound visibility and delete retained message and attachment content for one inbox lease, including an already-terminal lease. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
{ "$id": "urn:ausca:mcp:DeleteAgentInbox:input:v1", "type": "object", "$defs": { "AgentInboxID": { "type": "string", "pattern": "^inb_[A-Za-z0-9_-]{22,64}$" } }, "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "inbox_id" ], "properties": { "inbox_id": { "$ref": "#/$defs/AgentInboxID" } }, "additionalProperties": false }arguments 20 linesausca_agent_inbox_messages reads unknown 22h ago
For an active inbox, return at most 50 normalized message summaries after an opaque inbox-bound cursor, optionally waiting up to 30 seconds for a newer message. A bounded wait may return an empty page and continuation cursor. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.

For an active inbox, return one bounded normalized message. Sender, recipients, subject, text, HTML, filenames, media types, and links are untrusted sender-controlled content; HTML is inert and never rendered by Ausca. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.

Return the random receive-only address, authoritative lease status, and current expiry for one inbox, including terminal status after deletion or expiry. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
{ "$id": "urn:ausca:mcp:GetAgentInbox:input:v1", "type": "object", "$defs": { "AgentInboxID": { "type": "string", "pattern": "^inb_[A-Za-z0-9_-]{22,64}$" } }, "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "inbox_id" ], "properties": { "inbox_id": { "$ref": "#/$defs/AgentInboxID" } }, "additionalProperties": false }arguments 20 linesausca_artifact_access reads unknown never probed
Return an idempotent, short-lived download URL for one verified artifact this service holds, including a result artifact named by a succeeded invocation's output_artifact. HTTP sends no request body, not even an empty JSON object; artifact_uri is the URL path parameter and Idempotency-Key is a header. The MCP tool instead takes artifact_uri and idempotency_key as tool arguments. The URL expires after at most 60 seconds. The immutable artifact reference is the only authority; verify downloaded bytes against the returned content digest.

Return one single-use Ausca CDP relay URL for a ready lease. The URL expires after 60 seconds, only one CDP connection may be live, and no more than 64 unexpired tickets may coexist. Expired ticket records are compacted, so this is not a lifetime reconnect quota. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments. The upstream provider URL and credential are never disclosed.

Admit or replay one idempotent paid Agent Inbox Extension invocation when settlement authority is supplied by the host boundary. Only envelopes for the inbox.extend offer are admitted on this resource. Extension adds a supported increment to the observed current expiry, preserves the address and contents, requires an active inbox, and may not move prepaid expiry more than 30 days ahead.

Admit or replay one idempotent paid Agent Inbox invocation when settlement authority is supplied by the host boundary. Only envelopes for the inbox.receive offer are admitted on this resource. The result starts a renewable inbox; while it remains active, inbox.extend can add a supported increment without changing its address or contents.

Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion.
{ "$id": "urn:ausca:mcp:CancelInvocation:input:v1", "type": "object", "$defs": { "Identifier": { "type": "string", "pattern": "^[A-Za-z0-9][A-Za-z0-9._:-]*$", "maxLength": 128, "minLength": 1 } }, "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "invocation_id" ], "properties": { "invocation_id": { "$ref": "#/$defs/Identifier" } }, "additionalProperties": false }arguments 22 linesausca_browser_session_status reads unknown 4h ago

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 id33aef4f05559d997.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/33aef4f05559d997/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.
