Predge Whale Data MCP

An MCP server that exposes Polymarket whale trades, smart-money signals, and signed settlement outcomes as agent tools. It handles x402 USDC micropayments automatically, allowing agents to query whale activity, wallet profiles, and market consensus without managing API keys or gas fees directly.
