Coinbase’s Ethereum layer-2 network Base released a new tool this week called Base MCP. It lets users manage their crypto wallets and DeFi apps through AI assistants like ChatGPT, Claude and Cursor. The tool taps the Model Context Protocol, or MCP — an emerging standard for building secure interfaces between AI models and external tools.
Wallets and DeFi, via chat
Base MCP works by connecting a user’s Base Account directly to an AI client. Once linked, you can ask the AI to check balances, send transactions, or interact with DeFi protocols. The commands go through MCP, which handles authentication and limits what the AI can actually do on-chain. No private keys leave your control.
The tool is aimed at developers and power users who want to speed up routine actions — swapping tokens, checking positions, or managing multiple wallets — without clicking through a browser interface. Base says it’s a first step toward making crypto feel more like a conversation.
The protocol behind it
MCP is still relatively new, but it’s gaining traction as a way for AI models to call functions without opening the floodgates. Instead of giving an AI full access to a wallet, MCP lets you define exactly which actions it’s allowed to take and under what conditions. Base is one of the first L2s to bake this standard into a consumer-facing product.
That matters because most crypto-AI experiments so far have been either gimmicky or insecure. Base MCP flips that: it’s built on an open protocol, so other wallets and chains could adopt the same approach. Coinbase hasn’t said whether it plans to expand MCP support to its main platform, but the choice of Base suggests they’re testing the waters before a wider rollout.
Right now, Base MCP is available to anyone with a Base account and access to ChatGPT, Claude or Cursor. You install the MCP server, link your account, and start giving commands. The setup is straightforward but still requires some technical comfort — this isn’t a one-click app for grandma yet.
The real test will be whether users actually trust an AI to move their money. Base MCP’s design tries to solve that with scoped permissions and the ability to review each action before it executes. Still, it’s a big leap from “chatbot helps you write code” to “chatbot sends your ETH to a Uniswap pool.”
No timeline has been given for expanded support, but the tool is live now. Base is accepting feedback from early users, and the next obvious step is adding more DeFi protocols and maybe integrating with mobile apps. For now, it’s a glimpse of a future where you don’t have to open a wallet app at all — you just ask.
