| Tool | What it does | Hint |
|---|---|---|
ausca_agent_inbox_attachmentMint clean attachment access | 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… | writes |
ausca_agent_inbox_deleteDelete an agent-inbox lease | 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… | writes |
ausca_agent_inbox_messagesWait for or list inbound 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… | read-only |
ausca_agent_inbox_readRead one inbound message | 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.… | read-only |
ausca_agent_inbox_statusRead agent-inbox lease 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… | read-only |
ausca_artifact_accessMint artifact download 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… | writes |
ausca_browser_session_closeClose a browser-session lease | 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. | writes |
ausca_browser_session_connectMint a browser CDP connection | 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… | writes |
ausca_browser_session_statusRead browser-session lease 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_invocationRequest bounded cancellation | Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion. | writes |
ausca_extend_inboxAdmit or replay one Agent Inbox Extension invocation | 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… | writes |
ausca_get_invocationRead authoritative invocation state | 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_offerResolve an active or pinned offer revision | 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_browserAdmit or replay one Browser Session invocation | 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. | writes |
ausca_open_inboxAdmit or replay one Agent Inbox invocation | 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… | writes |
ausca_prepare_invocationValidate invocation input and return binding terms | Validate one exact invocation envelope and return immutable preparation terms or a typed refusal. Preparation never accepts payment material from model-authored tool arguments. | writes |
ausca_search_offersSearch immutable 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 |
