Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

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

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.

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.

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.

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.

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.

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_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.

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.

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.

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_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.

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_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.

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.

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 17 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_artifact_access and 11 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 92 of 92 checks got a reply (100.0%), average response time 381 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 in the form 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 17 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 381 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Ausca?

The npm package ausca was installed 32 times in the last week. Week over week that is -33%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Ausca open source?

The code is open source: it is published under the MIT licence, written in TypeScript, 40 stars on GitHub and 7 open issues. The licence covers the code in the repository, not the hosted service at ausca.com, which runs on its operator's own terms.
