         "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"
           }
         }
       }
     }
     

   • Alternatively, install the server with magnet-desktop.

💡 Key Use Cases in AI Workflows

Use Case 1: Automated Payment Processing AI applications can use this MCP server to automate payment processing by scheduling USDC transfers based on predefined criteria. For instance, an AI-driven finance bot could use the Free USDC Transfer MCP Server to send daily reimbursements via Base.

Use Case 2: Marketplace Settlements e-commerce platforms can leverage the Free USDC Transfer MCP Server to facilitate secure and feeless settlements between sellers and buyers.

🔌 Integration with MCP Clients

The following AI applications fully support integration with this MCP server:

• Claude Desktop: Supports full compatibility for all functions.
• Continue: Supports most functions but lacks prompt creation capabilities due to its model context limitations.
• Cursor: Limited to data tool integrations and not suitable for complex workflow setup.

Example Integration Code

{
  "mcpServers": {
    "free-usdc-transfer": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-free-usdc-transfer"],
      "env": {
        "COINBASE_CDP_API_KEY_NAME": "your_api_key_name",
        "COINBASE_CDP_PRIVATE_KEY": "private_key_here"
      }
    }
  }
}
