Payment infrastructure MCP server enabling AI agents to make gasless USDC payments on Base and JIT single-use virtual card checkouts, with zero-trust card handling, merchant checkout hints, and signed receipts.
Deterministic, auditable payment policy enforcement for AI agents. It provides pre-action authorization with scopes, budgets, allowlists, and signed mandates via an MCP server.
Budget & cost control for AI agents: hard per-agent spend caps, rate limits,
idempotency, and human-in-the-loop approval — enforced before each LLM call, not
after the invoice. One hosted MCP endpoint (no proxy or self-hosting), settled
via x402 (USDC on Base).
