AI-native payment infrastructure that gives AI agents isolated wallets with programmable spending policies for autonomous USDC stablecoin transactions.

11 MCP tools for Claude Desktop, Cursor, and Windsurf:

  • check_balance, send_payment, list_transactions, agent_info
  • create_invoice, pay_invoice, check_invoice_status, list_invoices
  • call_x402_endpoint, call_mpp_endpoint, plus more

Tri-rail support: x402 (HTTP-native micropayments), MPP (session-based streaming), and traditional fiat. Multi-chain USDC on Polygon PoS, Base, and Tempo with sub-second settlement.

Non-custodial wallets with Shamir key splitting — your keys, never ours.

Programmable spending policies (daily caps, per-transaction caps, recipient allowlists, cooldowns) enforced at the infrastructure level. Your agent literally cannot overspend regardless of prompt injection or buggy retry loops.

Free tier — no credit card, no KYC, no geographic gating.

Server tool list (11)

Raw names from tools/list. Only developers need these.

check_balanceReturns the agent wallet's current USDC balance, daily spending limit, amount spent today, and remaining daily allowance.
list_transactionsReturns recent transaction history for the agent wallet. Filter by status and control how many records are returned.
agent_infoReturns metadata about the agent: name, ID, wallet address, status, USDC balance, and spending limits.
send_paymentSends a USDC payment from the agent wallet to a recipient address. Enforces per-transaction and daily spending limits.
call_x402_endpointCalls an x402-protected API endpoint. Automatically handles the HTTP 402 payment flow: probes the endpoint, pays if required, and returns the response data. If a matching Grantex spend grant exists, its JWT is auto-attached so servers can verify scope and budget.
list_active_grantsReturns the agent's active spend grants — endpoint, remaining budget, and expiry. An agent uses this to discover what it is pre-authorized to pay for.
create_invoiceCreates a USDC invoice for the agent. Returns a payment URL that can be shared with the payer. The payment is detected automatically when USDC arrives at the agent's wallet.
check_invoice_statusChecks the current status of an invoice. Returns amount, payment status, and payment URL.
list_invoicesLists invoices created by this agent. Optionally filter by status (pending, partial, paid, expired, cancelled).
pay_invoicePay an invoice by invoice ID. The agent's wallet will be charged the invoice amount and the invoice will be marked as paid.
call_mpp_endpointCalls an MPP-paywalled HTTP endpoint. The agent pays using stablecoins on Tempo via the Machine Payments Protocol (MPP). Supports 100+ MPP-compatible services. The agent must be on a Tempo chain.
