Free USDC Transfer MCP Server

An MCP server implementation enabling free USDC transfers on Base with Coinbase CDP MPC Wallet integration.

Features

• Free USDC Transfers: Send USDC to any address or ENS/BaseName domain on Base - no fees, just simple transfers
• Coinbase MPC Wallet: Create and manage your Coinbase MPC wallet for secure, feeless transactions
• Name Resolution: Automatic support for ENS and BaseName domains

Functions

tranfer-usdc

• Description: Analyze the value of the purchased items and transfer USDC to the recipient via the Base chain. Due to the uncertainty of blockchain transaction times, the transaction is only scheduled here and will not wait for the transaction to be completed.
• Inputs:
  • usdc_amount (number): USDC amount, greater than 0.
  • recipient (string): Recipient’s on-chain address or ENS domain (e.g., example.eth).
• Behavior:
  • Verifies the recipient’s address or resolves ENS domains.
  • Schedules a USDC transfer on the Base chain.
  • Provides a link to view transaction details on BaseScan.

create_coinbase_mpc_wallet

• Description: Create a Coinbase MPC wallet address.
• Behavior:
  • Creates a new Coinbase MPC wallet and saves the seed to a secure file.
  • If a wallet already exists, returns the existing wallet address.
  • The seed file for Coinbase MPC wallets is stored in the Documents directory under the file name mpc_info.json.
