Coinbase's Base Launches MCP Tool for AI Agents to Manage Crypto Wallets and DeFi

Coinbase-incubated Base is an Ethereum Layer 2 network. Base MCP uses the MCP standard initiated by Anthropic to connect AI services such as ChatGPT and Claude with Base Account. The design brings wallet and DeFi functions into conversational interfaces, but agents do not hold private keys and users must still approve every transaction.

Base announced the launch of Base MCP on May 26, 2026, initially supporting seven services: Morpho, Moonwell, Aerodrome, Bankr, Avantis, Virtuals and Uniswap. Users can check balances, transfer funds, swap tokens and interact with DeFi applications, with a preview of asset changes shown before confirmation. The related x402 protocol processed about $1.1 million over the past 30 days.
