Base MCP gives your AI assistant direct access to your Base Account (the smart wallet powering the Base App). Connect once and your assistant can check balances, send funds, swap tokens, sign messages, execute contract calls, and pay x402-enabled APIs across multiple networks. Every write action requires your approval.Documentation Index
