MCP
Ledger MCP Server
Ledger's Model Context Protocol (MCP) lets AI agents directly manage their financial tools through a standardized interface. Using MCP, agents can create wallets, issue virtual cards, set spend controls, freeze or delete cards, and review balances and transaction histories — all in a secure, machine-readable format.
MCP works across all Ledger products, so your agents can reason about funds, take action instantly, and stay within the guardrails you define.
import { MCPClient, Tool } from '@modelcontextprotocol/sdk';
import { LedgerAPI } from '@ledger/mcp-server';
const mcpClient = new MCPClient('ledger://financial-tools');
const CreateCardTool = new Tool({
name: 'create_virtual_card',
description: 'Issue a new virtual card for agent payments'
});
await mcpClient.callTool('create_virtual_card', {
limit: 500.00,
merchant_category: 'software',
single_use: true
});
Pricing
Fair and transparent usage-based pricing.
Simple, transparent pricing that scales with your agents. Start free, pay only for real usage as you grow.
About
Building the financial OS for the agent economy.
AI agents will soon handle billions of transactions. They will need to pay suppliers, purchase services, and manage expenses across countless workflows. The current financial system was not designed for this future.
We believe commerce should be as autonomous as the agents driving it. Imagine a world where AI can transact seamlessly on any platform, pay for any service, and run complex financial workflows without human intervention. A world where agents are deployed with full confidence, knowing every transaction is tracked, every policy is enforced, and every dollar is accounted for.
