"ZAP" matching MCP servers:

MAP (Maraventano Agent Protocol). One MCP server with three subtractive parts — Merchant Key (read any product URL into one CleanRead), Atlas (publish your own catalog by reading yourself), Provisions (wallet curriculum), Teacher, not butler: never signs, pays, or holds keys.

Enables agents to inspect pot balances, deposits, deposit addresses, and spend approvals, and to pay for PaidResources on spark/USDB or send to allowlisted Spark addresses within a per-spend cap. Transactions above the cap become human approval tickets, and the pot key remains in the OS keychain so nothing is signed until approval.

Exposes the SAI Verified Agent Protocol as MCP tools so clients acting in agent, verifier, or executor scopes can prepare and submit actions and proposals, submit attestations, and execute approved payments, with status and receipt lookups. Scope selection limits which tools are available per session.

Enables to interact with Tap Payments gateway for charges, refunds, customers, and invoices via Bearer token auth.
