Base launched MCP, letting AI agents connect directly to crypto wallets and DeFi apps through natural language commands.
Crypto News
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
Base MCP is fully non-custodial. The MCP server never holds access to a user's private keys. When an AI agent initiates a transaction, the system stores it locally as a pending request, and the user's Base Account retrieves it for manual review before any signing takes place.
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.
The release follows a broader industry shift toward AI-driven systems capable of executing blockchain transactions on behalf of users. Gemini launched an MCP-based trading tool in April 2026, and Amazon Web Services introduced an AI agent payment system using Coinbase's x402 protocol in May 2026, both targeting the intersection of AI and crypto infrastructure.
Base framed the product as an early step toward AI-native internet interfaces. "Instead of forcing users to jump between apps, parse protocol interfaces, or know exactly which action to take, Base MCP lets your agent help you navigate the ecosystem in a more personalized and understandable way," the company wrote in its announcement. The company added that as more users adopt AI agents as a primary internet interface, applications will need new ways to appear inside those environments.
MCP is an open standard first developed by Anthropic. Its growing support across major AI clients gives Base a distribution path that does not require building separate front-ends for each supported DeFi protocol.
