Base introduces MCP gateway for agent tokenization and commerce

Imagine telling your AI assistant to rebalance your DeFi portfolio, and it actually does it. Not in some sandbox demo, not on a testnet, but across seven live protocols on a major Layer 2 blockchain. That’s the pitch behind Base MCP, which launched on May 26.

Base, the Coinbase-backed Layer 2 chain, rolled out its Model Context Protocol gateway, giving AI agents a direct line into onchain accounts. The system lets agents perform swaps, transfers, lending, perpetual trading, and portfolio tracking, all while keeping private keys firmly out of the agent’s reach.

How it works, and why keys stay safe

The Model Context Protocol itself was introduced by Anthropic back in November 2024 as a standardized way for AI models to interact with external tools and data sources. Base has built a gateway on top of this protocol that connects AI agents to user Base Accounts through a plugin architecture.

The agent never touches your keys. Transaction details are constructed locally by the agent and then presented to the user for explicit confirmation inside the Base App. The MCP server handles only pending requests. It doesn’t control keys, and it doesn’t execute transactions on its own.

This design also addresses one of crypto’s most persistent headaches: phishing. Because transactions are constructed locally rather than routed through external servers, the attack surface for malicious transaction injection shrinks considerably.

Seven protocols at launch

The initial rollout includes skill plugins for seven DeFi protocols, each covering a different corner of the ecosystem. Morpho handles lending and borrowing. Moonwell provides lending markets. Uniswap covers swaps and liquidity. Avantis enables perpetual trading. Aerodrome manages liquidity pools. Bankr facilitates token actions. And Virtuals supports agent and token launches.

Virtuals’ inclusion means the gateway doesn’t just let agents interact with existing DeFi infrastructure. It lets them launch new agents and tokens, effectively creating a system where AI can spawn more AI-driven financial products.

The supported AI interfaces at launch include Claude, ChatGPT, and Cursor. Core actions available through the gateway include portfolio tracking, transaction history review, token swaps, and direct interaction with each of the seven DeFi protocols.
