AI agents can now make Mastercard purchases through Crossmint's Lobster.cash

Crossmint's Lobster.cash — an open payment standard that gives AI agents virtual cards with spending limits and human approval workflows — has added Mastercard Agent Pay support, expanding beyond its initial Visa-only rails. The integration means AI agents built on platforms like Claude Code, Cursor, and OpenClaw can now autonomously complete purchases across both major card networks through a single Crossmint integration. Lobster.cash keeps card numbers and private keys out of the agent's context entirely, addressing prompt injection risks that come with agents handling raw payment credentials.
