This MCP server enables AI agents to verify B20 tokens on the Base blockchain by checking issuer powers, detecting imposter tokens, and retrieving signed EIP-712 verdicts. It supports both a free rate-limited demo route and a paid x402 endpoint for unmetered access, allowing agents to assess token safety without trusting the API blindly.
