## Documentation & README

# mcp-server

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.

## Connect

Streamable HTTP endpoint:

```
https://ausca.com/mcp
```

Claude Desktop / Claude Code:

```json
{
  "mcpServers": {
    "ausca": {
      "type": "http",
      "url": "https://ausca.com/mcp"
    }
  }
}
```

## Tools

**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. |

## How to use it

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`.
