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

How It Works

Code

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.
