Base Launches MCP Tool Connecting AI Agents to Crypto Wallets

Coinbase's Ethereum (ETH) layer-2 network Base released a protocol on May 26 that lets AI agents interact directly with users' crypto wallets and decentralized finance (DeFi) applications through plain-language instructions. The tool is called Base MCP and uses the Model Context Protocol (MCP), an open standard that allows AI systems to connect with external applications. Users can link their Base Accounts to AI interfaces, including ChatGPT, Cursor, and Claude, by downloading the integration within those clients. Once connected, users can ask their AI agent to send funds, swap tokens, check balances, review transaction history, and access DeFi protocols on Base without opening a separate app or website. ## Safeguards Against Common Attack Vectors The tool uses OAuth 2.1 for authentication, the same standard used by “Sign in with Google.” Because transactions are built locally rather than fetched from an external site, the system reduces exposure to phishing and domain hijacking, two common vulnerabilities in web-based crypto applications. At launch, Base MCP connects to lending platforms Morpho and Moonwell, decentralized exchange Uniswap, perpetuals trading platform Avantis, and additional protocols including Aerodrome, Bankr, and Virtuals. Supported functions cover lending, token swaps, liquidity management, perpetuals trading, and access to new token and agent launches on Base. **Source:** CMC News.
