Free USDC Transfer MCP Server

Overview

Free USDC Transfer is an MCP server that enables fee-free USDC transfers on the Base blockchain using Coinbase CDP's MPC Wallet technology. This server allows you to create a secure wallet and send USDC to any address or ENS/BaseName domain without paying transaction fees.

Prerequisites

Before using this MCP server, you'll need:

1. A Coinbase CDP account
2. API credentials from the Coinbase CDP developer portal

Installation

Setting up with Claude Desktop

Add the following configuration to your claude_desktop_config.json file:

{
  "mcpServers": {
    "free-usdc-transfer": {
      "command": "npx",
      "args": [
        "-y",
        "@magnetai/free-usdc-transfer"
      ],
      "env": {
        "COINBASE_CDP_API_KEY_NAME": "YOUR_COINBASE_CDP_API_KEY_NAME",
        "COINBASE_CDP_PRIVATE_KEY": "YOUR_COINBASE_CDP_PRIVATE_KEY"
      }
    }
  }
}

Replace YOUR_COINBASE_CDP_API_KEY_NAME and YOUR_COINBASE_CDP_PRIVATE_KEY with your actual Coinbase CDP credentials.

Alternative Installation with Magnet Desktop

You can also install this server using magnet-desktop, which provides a more streamlined setup process.

Getting Coinbase CDP API Credentials

1. Sign up for a Coinbase CDP account at portal.cdp.coinbase.com
2. Navigate to the developer dashboard
3. Generate an API key and save both the key name and private key
4. Add these credentials to your configuration as shown above

Usage

Once installed, you can use the MCP server to:

1. Create a Coinbase MPC wallet
2. Send fee-free USDC transfers to any address or ENS/BaseName domain on Base

The server handles all the complexities of blockchain transactions, including address verification and name resolution for ENS and BaseName domains.

Security Notes

• The seed file for your Coinbase MPC wallet is stored in the Documents directory as mpc_info.json
• Keep your Coinbase CDP API credentials secure and never share them
• While transactions are fee-free, they still require confirmation on the Base blockchain

Troubleshooting

If you encounter issues:

1. Verify your Coinbase CDP API credentials are correct
2. Ensure you have sufficient USDC in your wallet for transfers
3. Check that recipient addresses or ENS domains are valid
4. For transaction status, use the BaseScan link provided after initiating a transfer
