Free USDC Transfer
★ 21from magnetai
Enables free USDC transfers on the Base network using a Coinbase CDP MPC Wallet.
⌁ labsco summary — our analysis, not the vendor's
What it is — An MCP server that lets an AI assistant send USDC on the Base network with no transfer fees, using a Coinbase CDP MPC wallet.
What you get —
tranfer-usdc— schedule a feeless USDC transfer to an address or ENS/BaseName domain, with a BaseScan link to view itcreate_coinbase_mpc_wallet— create/manage a Coinbase MPC wallet, seed saved locally tompc_info.json- Automatic ENS and BaseName resolution, e.g. "send 5 USDC to example.eth"
Requirements — A Coinbase CDP account with API credentials: COINBASE_CDP_API_KEY_NAME and COINBASE_CDP_PRIVATE_KEY.
Cost snapshot — The server is free and open source (MIT), on npm as @magnetai/free-usdc-transfer. Transfers are advertised as feeless on Base, but it requires a Coinbase CDP account and moves real funds via that paid platform.
Setup effort — npx -y @magnetai/free-usdc-transfer with your CDP key/private key in env, or install via magnet-desktop.
Our take — Interesting for programmatic on-chain payments, but letting an LLM initiate real money transfers is high-risk: the wallet seed is stored in a local file and transfers are only scheduled (not confirmed) at call time, so treat approvals and key security very carefully.

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.
