Ausca does not always answer

Over the last week it answered 99.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ausca

ausca_agent_inbox_attachment

Return one short-lived Ausca download URL only when the exact stored attachment has a clean safety verdict.

ausca_agent_inbox_delete

Idempotently stop inbound visibility and delete retained message and attachment content for one inbox lease.

ausca_agent_inbox_messages

Return at most 50 normalized message summaries after an opaque cursor, optionally waiting up to 30 seconds for a newer message.

ausca_agent_inbox_read

Return one bounded normalized message. HTML is inert untrusted content and is never rendered by Ausca.

ausca_agent_inbox_status

Return the random receive-only address, authoritative lease status, and expiry for one inbox.

ausca_browser_session_close

Idempotently terminate the CDP relay and upstream browser for one lease. Closing never creates another payment.

ausca_browser_session_connect

Return one short-lived Ausca CDP relay URL for an active lease. The upstream provider URL and credential are never disclosed.

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.

ausca_cancel_invocation

Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion.

ausca_get_invocation

Read the authoritative durable state, output commitment, and receipt reference for one invocation without creating a new purchase or retry identity.

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.

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.

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.

Ausca — questions

Answers built from our own checks of this server.

What can Ausca do?

It exposes 13 tools, read directly from the server on our last check. Among them: ausca_agent_inbox_attachment, ausca_agent_inbox_delete, ausca_agent_inbox_messages, ausca_agent_inbox_read, ausca_agent_inbox_status, ausca_browser_session_close and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Ausca working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 319 ms. The bar chart above shows every period we have measured.

How do I connect Ausca?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Ausca need an API key?

No. Ausca completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Ausca?

It answers our handshake in 319 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
