Base Free USDC Transfer

What is mcp-free-usdc-transfer?

mcp-free-usdc-transfer is an MCP (Model Context Protocol) server that enables free USDC transfers on the Base network. It leverages Coinbase CDP (Coinbase Decentralized Protocol) for secure MPC (Multi-Party Computation) wallet integration, allowing users to send USDC without incurring transaction fees.

How to use mcp-free-usdc-transfer?

To use mcp-free-usdc-transfer, you first need to obtain a Coinbase CDP API key. After signing up for a Coinbase CDP account and generating your API key, you can configure the MCP server. This can be done by adding a specific JSON configuration to your claude_desktop_config.json file, which includes your Coinbase CDP API key name and private key. Alternatively, you can install the server using magnet-desktop.

Once configured, you can utilize the provided functions:

• transfer-usdc: This function allows you to specify a USDC amount and a recipient (on-chain address or ENS/BaseName domain) to schedule a free USDC transfer on the Base chain. It provides a link to view transaction details on BaseScan.
• create_coinbase_mpc_wallet: This function creates a new Coinbase MPC wallet address. If a wallet already exists, it returns the existing address. The wallet seed is securely stored in mpc_info.json in your Documents directory.
