One authority, another projection
Connect a Streamable HTTP MCP client to https://ausca.com/mcp. MCP tools are generated from the canonical OpenAPI document. Tool names, input schemas, output schemas, and safety annotations are projections, not independently authored behavior.
Payment stays at the invocation boundary
MCP does not carry x402 HTTP headers. A governed host may enable the paid invocation tool and coordinate authority, but the tool remains disabled by default and the underlying paid invocation owns settlement and receipt state.
Generated tool surface
Safety labels below come from the generated MCP descriptor, including the paid invocation default.
ausca_cancel_invocation Request bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion.
- May mutate
- Enabled by default
- Destructive annotation
ausca_get_invocation Read the authoritative durable state, output commitment, and receipt reference for one invocation without creating a new purchase or retry identity.
- Read only
- Enabled by default
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.
- Read only
- Enabled by default
ausca_invoke_offer Admit or replay one idempotent paid invocation when settlement authority is supplied by the host boundary. The public MCP transport keeps this tool disabled; paid callers use the canonical HTTP resource.
- May mutate
- Disabled by default
- Destructive annotation
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.
- May mutate
- Enabled by default
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.
- Read only
- Enabled by default
