Base extends Model Context Protocol (MCP) clients' capabilities by providing onchain tools for AI applications, like Claude Desktop and Cursor, to interact with the Base Network and Coinbase API. It allows users to retrieve wallet addresses, list balances, transfer funds, deploy contracts, interact with Morpho vaults, call contract functions, onramp funds via Coinbase, manage ERC20 tokens, and buy OpenRouter credits with USDC. Designed for extensibility, it enables the addition of third-party protocols, tools, and data sources, powered by Base Developer Tools and AgentKit.
