Authoryze MCP server lets AI agents request purchases under merchant, amount, and spending-limit controls. It runs as a remote MCP endpoint and authenticates clients through OAuth 2.1 with PKCE or a static bearer-token API key. Approved requests can produce a single-use virtual card whose details are exposed only once. Reach for it when an agent needs controlled purchasing with owner approval and account-level spending visibility; availability is currently limited to US-issued cards.
