Base Token Facts MCP

An MCP server for AI agents on Base that provides token verdicts, sell checks, wallet snapshots, gas prices, transaction summaries, and Basename lookups. It simulates buy/sell transactions to report taxes and round-trip losses without sending on-chain transactions, with payments handled per call in USDC via x402.
