Coinbase’s Base Unveils ‘Base MCP’ On-Chain Finance Infrastructure for AI Agents

Base, the Ethereum layer-2 network developed by Coinbase, has unveiled Base MCP, a new tool that lets artificial intelligence models interact with blockchain accounts.

Catenaa reported on May 30 that Base MCP links AI models such as ChatGPT and Claude to a user’s Base account, enabling functions including token swaps, balance checks, transfers and access to decentralized applications, or dApps.

Users can request blockchain actions through a chat interface, and the AI generates a transaction based on the request. The transaction is executed only if the user approves it.

Base said the system was designed so AI agents cannot access private keys. When a transaction request is generated, the user’s Base wallet opens separately, and the transaction is carried out only after final approval.

Base MCP integrates with major decentralized finance, or DeFi, protocols including Uniswap, Morpho, Moonwell, Aerodrome and Virtuals. That allows users to access on-chain financial services through an AI interface.

The launch follows Coinbase’s release last year of x402, an AI payments protocol designed to support stablecoin payments in AI-based internet service environments.
