MCP is an interface, not a backend. Business rules live in the domain services and the gateway enforces authorization in one place, so a tool call and the equivalent REST call are subject to identical checks. There is no logic that exists only on the MCP side, and therefore no behaviour that can drift between them.

Authorization

The MCP server is an OAuth protected resource. Clients discover the authorization server through protected-resource metadata and run the same authorization-code + PKCE flow.
Tokens are audience-bound. A token minted for Ryde is only accepted by Ryde, and must never be forwarded to another service.
401 means authentication is missing or invalid. 403 means authenticated but not permitted — either a missing scope or a missing entitlement, distinguished by the error code.
tools/list is filtered by the scopes the customer granted.

Transacting tools stay VISIBLE to a customer without Ryde One, carrying the requirement in their description. Hiding them would leave an agent unable to explain why it cannot help — the customer would just be told no. Showing them lets the agent price the thing, then explain exactly what a membership unlocks.
