Laso Finance

Overview

Laso Finance turns USDC into prepaid cards, gift cards and fiat payouts (laso.finance). Its agent guide lists what an agent can do: order single-load or reloadable prepaid cards, buy gift cards, send via Venmo, PayPal or push-to-debit, make ACH transfers to registered US banks, and pay other x402 endpoints on behalf of agent wallets. It is reachable through direct x402 calls settled in USDC on Base or Solana, an MCP server at laso.finance/mcp, WebMCP, and an OpenAPI spec plus SKILL.md.

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
