CabalSpy MCP Server

Real-time crypto wallet tracking for AI assistants. CabalSpy monitors labeled wallets — key opinion leaders (KOLs), smart money and whales — across Solana, BNB Chain, Base and Ethereum, and exposes the data as Model Context Protocol (MCP) tools.

Connect it to Claude, Cursor, or any MCP client and ask about on-chain trading activity in plain language.
