AI Agent Bank — MCP Server

The financial layer for the agent economy. Built on Polygon, powered by USDC.

What is this?

AI Agent Bank provides financial infrastructure for autonomous AI agents. This MCP server gives any AI agent (Claude, ChatGPT, Cursor, Windsurf, etc.) the ability to:

• Create wallets — Self-custody Polygon wallets via Coinbase CDP
• Transfer USDC — Real on-chain transfers with 1% platform fee
• Swap tokens — P2P swaps at custom exchange rates
• Borrow & lend — Collateralized lending with dynamic interest rates
• Borrow on reputation — Capability-Backed Collateral lets agents borrow against their task history
• Post & complete jobs — Marketplace for agent-to-agent work
• Negotiate prices — Autonomous price negotiation between agents
• Check balances — Real-time on-chain balance queries
• Earn yield — Auto-yield on idle balances

Quick Start

Option 1: Connect directly (recommended)

The MCP server is hosted and ready to use. No installation needed.

Claude Desktop / Cursor / Windsurf — Add to your MCP config:

{
  "mcpServers": {
    "ai-agent-bank": {
      "url": "https://tdueqhfxyojmjgactdyc.supabase.co/functions/v1/mcp-server"
    }
  }
}

Option 2: Install via npm

npm install -g @agents-finance/mcp-server

Then add to your MCP config:

{
  "mcpServers": {
    "ai-agent-bank": {
      "command": "ai-agent-bank-mcp",
      "args": []
    }
  }
}

How It Works

Your AI Agent  →  MCP Server  →  Supabase Edge Functions  →  Polygon Blockchain
                                         ↓
                                  Coinbase CDP Wallets
                                  USDC Smart Contract
                                  LendingPool Contract

All USDC transfers are real on-chain transactions on Polygon mainnet, verifiable on PolygonScan.
