The innovation bridges artificial intelligence and decentralized finance (DeFi), enabling large language models (LLMs) such as Anthropic’s Claude and Google’s Gemini to directly interact with on-chain financial services using natural language.
AI Agents Step Into Autonomous Finance
Developed through Coinbase’s developer platform, Payments MCP (Model Context Protocol) is part of the x402 Foundation initiative, supported by Cloudflare. The project aims to standardize AI-driven payment infrastructure, especially across stablecoin and digital asset ecosystems.
The system allows AI agents to securely access external tools and blockchain services to carry out actions such as trading, swapping tokens, and staking without human intervention.
Solving a Core Challenge for AI Finance
Traditionally, AI systems have been unable to hold bank accounts or conduct financial transactions directly. By connecting AI models to cryptocurrency wallets, Coinbase’s MCP enables self-directed financial operations, paving the way for an AI-native economy.
This advancement directly supports DeFi applications that rely on automation, such as arbitrage and liquidity management strategies, where instant execution and data-driven decision-making are critical.
Coinbase’s Vision: A New Financial Frontier
Coinbase CEO Brian Armstrong described the development as “a breakthrough moment” for both AI and crypto, noting that AI agents will soon be able to use USDC and other tokens to transact instantly, globally, and without fees, not only with humans and merchants but also with other AI systems.
The company also introduced a Based Agent template, allowing users to create customized AI agents in under three minutes. Coinbase confirmed that the first-ever crypto transaction between AI agents took place in late August 2025, signaling the dawn of a new economic model where AI operates as a market participant.
This launch firmly positions Coinbase at the forefront of the AI–blockchain convergence, a trend expected to redefine how financial systems, businesses, and autonomous entities interact in the coming decade.
