Budget-bound x402 payment wallet for AI agents — pays HTTP 402 URLs, capped locally. No backend.

Install

claude mcp add mcp -- npx -y @piprail/[email protected]

Requires: PIPRAIL_PRIVATE_KEY, PIPRAIL_CHAIN, PIPRAIL_CHAINS, PIPRAIL_MAX_AMOUNT, PIPRAIL_MAX_TOTAL, PIPRAIL_MAX_TOTAL_DENOM, PIPRAIL_MAX_PAYMENTS, PIPRAIL_MAX_PAYMENTS_PER_WINDOW, PIPRAIL_WARN_AT_FRACTION, PIPRAIL_SPEND_LOG, PIPRAIL_EVENT_LOG, PIPRAIL_TOKENS, PIPRAIL_SCHEMES

Our take

Implements a local, budget-capped wallet for agents that need to pay HTTP 402 endpoints, without requiring a hosted backend. It is for developers working on paid API or agent commerce flows who want strict local spending controls. The idea is narrow but concrete; maturity looks modest, though the constraints-first design is a good sign for a finance-adjacent tool.
