It answers at https://ausca.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 18 October 2026, succeeded.
Pay-per-call APIs and MCP services for agents, no accounts or keys, with verifiable receipts.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 con Inputs: attachment_id, idempotency_key, inbox_id, message_id |
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. Inputs: inbox_id |
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 lea Inputs: after, inbox_id, wait_seconds |
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 bear Inputs: inbox_id, message_id |
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 Inputs: inbox_id |
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. The URL expires after at most 60 seconds. The immutable artifact ref Inputs: artifact_ref, idempotency_key |
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. Inputs: session_id |
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 li Inputs: idempotency_key, session_id |
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. Inputs: session_id |
ausca_cancel_invocation | Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion. Inputs: invocation_id |
ausca_get_invocation | Read the authoritative durable state, output commitment, and receipt reference for one invocation without creating a new purchase or retry identity. Inputs: invocation_id |
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. Inputs: offer_id, revision_digest |
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. Inputs: canonicalizer_version, idempotency_key, input, input_schema_digest, offer_id, offer_revision |
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. Inputs: cursor, limit, q |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://ausca.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
