Dev wires Stripe's agent payment protocol into a live MCP server for per-call USDC payments
schneida_vie · reddit · 2026-09-23
A developer running an MCP server for VC fund data swapped part of its signup/credit flow for Stripe's new agent payment protocol (MPP): agents can now pay per call in USDC straight from a wallet, no signup form, with a daily cap to avoid surprise bills. He notes the daily-limit logic was harder than the payment integration, and invites comparison with x402 and other wallet-based flows.
