Wallgent

Welcome to Wallgent

Financial infrastructure for AI agents. Wallets, payments, policies, and MCP tools.

What is Wallgent?

Wallgent is a financial infrastructure platform that enables AI agents to earn, hold, and spend money. It provides programmable wallets backed by a double-entry ledger, a policy engine for spending controls, and native MCP tool integration.

Core Components

  • Agent Wallets -- Programmable wallets holding USD stablecoins (USDC). Each wallet maps to a liability account in the ledger.
  • Double-Entry Ledger -- Every transaction produces balanced debit/credit entries. Immutable, auditable, and consistent.
  • Policy Engine -- Configurable spending rules: transaction limits, daily caps, approved/blocked recipients, time restrictions, and human approval gates.
  • MCP Financial Server -- Tools like check_balance, send_payment, and get_transactions that MCP-compatible agents can call directly.
  • TypeScript SDK -- Stripe-style resource API (wg.wallets, wg.payments, wg.policies) for server-side integration.
  • Developer Dashboard -- Monitor wallets, set policies, view transactions, and manage API keys.

The MCP server communicates with the REST API over HTTP -- it never touches the database directly. The policy engine evaluates every payment request before it reaches the ledger. All financial mutations go through the ledger service with pessimistic locking.
