Tools
| Tool | Description | Behaviour |
|---|---|---|
| ausca_agent_inbox_attachment | 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. | Changes data |
| ausca_agent_inbox_delete | 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. | Destructive |
| ausca_agent_inbox_messages | 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. | Read-only |
| ausca_agent_inbox_read | 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. | Read-only |
| ausca_agent_inbox_status | 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. | Read-only |
| ausca_artifact_access | 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_ref is the URL path parameter and Idempotency-Key is a header. The MCP tool instead takes artifact_ref 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. | Changes data |
| ausca_browser_session_close | Idempotently terminate the CDP relay and upstream browser for one lease. Closing never creates another payment. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments. | Destructive |
| ausca_browser_session_connect | 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. | Changes data |
| ausca_browser_session_status | Return authoritative status and expiry for one browser-session lease. The lease capability is supplied by the transport and is never a tool argument or response field. | Read-only |
| ausca_cancel_invocation | Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion. | Destructive |
| ausca_extend_inbox | 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. | Destructive |
| ausca_get_invocation | Read the authoritative durable state, output commitment, and receipt reference for one invocation without creating a new purchase or retry identity. | Read-only |
| ausca_get_offer | Resolve one active offer or an exact immutable revision, including the schema and revision digests required to construct a valid invocation envelope. | Read-only |
| ausca_lease_browser | Admit or replay one idempotent paid Browser Session invocation when settlement authority is supplied by the host boundary. Only envelopes for the browser.session offer are admitted on this resource. | Destructive |
| ausca_open_inbox | 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. | Destructive |
| ausca_prepare_invocation | Validate one exact invocation envelope and return immutable preparation terms or a typed refusal. Preparation never accepts payment material from model-authored tool arguments. | Changes data |
| ausca_search_offers | Search the current immutable Ausca offer catalog by free-text query. Returns stable offer identities and revision digests without creating product or payment state. | Read-only |
