Free USDC Transfer

What is Free USDC Transfer about?

Free USDC Transfer provides a Model Context Protocol (MCP) server that lets users send USDC on the Base blockchain without paying transaction fees. It leverages Coinbase CDP's MPC wallet for secure, feeless transactions and automatically resolves ENS and BaseName domains.

How to use Free USDC Transfer?

1. Obtain a Coinbase CDP API key – sign up at the Coinbase CDP portal and generate an API key.
2. Configure the MCP server (see the serverConfig section below) with the API key name and private key.
3. Call the exposed functions:
   • create_coinbase_mpc_wallet – creates or returns an existing MPC wallet address.
   • tranfer-usdc – schedules a USDC transfer by providing usdc_amount ( > 0 ) and a recipient (address, ENS, or BaseName).
4. The server returns a BaseScan link to view the scheduled transaction.

Key features of Free USDC Transfer

• Fee‑free USDC transfers on the Base chain.
• Coinbase MPC wallet integration for secure key management.
• ENS & BaseName support – resolves human‑readable domains to on‑chain addresses.
• Simple scheduling – transaction is queued and a explorer link is provided.

Use cases of Free USDC Transfer

• Developers building crypto‑enabled applications that need to move USDC without incurring gas costs.

• Businesses accepting USDC payments and preferring feeless settlements.
• Any workflow that requires automated USDC payouts to users identified by ENS/BaseName.

FAQ from the Free USDC Transfer

Q: Do I need any cryptocurrency to cover gas fees? A: No. The server uses Coinbase CDP’s MPC infrastructure to sponsor the transaction, making it fee‑free for the end user.

Q: Can I transfer to ENS names? A: Yes. The server automatically resolves ENS and BaseName domains to their underlying addresses.

Q: What happens if the transaction is delayed on‑chain? A: The function only schedules the transfer and returns a BaseScan link; you can monitor the transaction status there.

Q: Is the wallet seed stored securely? A: The seed is saved as mpc_info.json in the Documents directory, which should be protected by the host system.

Q: How do I integrate this with Claude Desktop? A: Add the provided snippet to claude_desktop_config.json under mcpServers and replace the placeholder environment variables with your Coinbase credentials.
