You can now tell ChatGPT to swap your ETH for USDC on Base, and it will actually do it. That’s the core pitch behind Base’s new Model Context Protocol integration, which launched on May 26 with Uniswap as a native plugin.
The Base MCP creates a direct bridge between AI assistants and onchain activity. Users type a conversational prompt like “Swap 0.05 ETH to USDC on Base,” and the AI agent handles the routing, execution logic, and transaction preparation on their behalf.
How the Base MCP actually works
Model Context Protocol is a standard that lets AI models interact with external tools and data sources in a structured way. Base has built its own MCP server that connects AI assistants — Claude, ChatGPT, and Cursor — directly to user Base Accounts, turning natural language into onchain actions.
Uniswap sits at the center of this launch as the primary swap and liquidity management layer. Users can execute token swaps, manage liquidity pool positions, check balances, sign messages, and execute contract calls, all through conversational prompts.
