Public metadata and connection docs for the Ausca MCP server.
Ausca exposes pay-per-call APIs and MCP services for agents. There are no accounts and no API keys. Every paid execution settles against an immutable offer revision and returns a verifiable receipt.
The server is hosted. There is nothing to install from this repository.

Offers
| Tool | What it does |
|---|---|
ausca_search_offers | Search the current immutable offer catalog by free-text query. Returns stable offer identities and revisions. |
ausca_get_offer | Resolve one active offer or an exact immutable revision, including the schema and revision digests. |
Invocations
| Tool | What it does |
|---|---|
ausca_prepare_invocation | Validate one exact invocation envelope and return immutable preparation terms or a typed refusal. |
ausca_get_invocation | Read the durable state, output commitment, and receipt reference for one invocation. |
ausca_cancel_invocation | Request bounded cancellation of one invocation. Idempotent, and may be refused. |
Agent inbox
| Tool | What it does |
|---|---|
ausca_agent_inbox_status | Return the receive-only address, lease status, and expiry for one inbox. |
ausca_agent_inbox_messages | Return up to 50 normalized message summaries after an opaque cursor. |
ausca_agent_inbox_read | Return one bounded normalized message. HTML is inert untrusted content and is never rendered. |
ausca_agent_inbox_attachment | Return a short-lived download URL, only when the stored attachment has a clean safety verdict. |
ausca_agent_inbox_delete | Stop inbound visibility and delete retained message and attachment content for one lease. |
Browser sessions
| Tool | What it does |
|---|---|
ausca_browser_session_status | Return status and expiry for one browser-session lease. |
ausca_browser_session_connect | Return a short-lived CDP relay URL for an active lease. The upstream provider URL and credential are never exposed. |
ausca_browser_session_close | Terminate the relay and upstream browser for one lease. Closing never creates a payment. |
Resolve an offer with ausca_search_offers and ausca_get_offer before acting, so the
work is bound to an exact immutable revision.
The public MCP transport does not accept wallets or payment credentials, and the
paid-invocation tool is not exposed over it. Paid execution goes through the canonical
HTTP invocation resource described by the selected service's SKILL.md.
