find_whale_followers
AI agents call find_whale_followers to retrieve information from Polymarket Research without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool operates within a read-only research server designed for investigating public Polymarket data. Despite the empty description, the server-level constraints and context—combined with the tool's analytical nature (finding followers of whale addresses)—indicate it retrieves and correlates existing data without creating, modifying, executing code, or causing destructive effects.
From the tool's definition Server is explicitly described as 'Read-only MCP server' backed by 'public APIs'. The tool name 'find_whale_followers' suggests querying/identifying relationships in publicly available market data, consistent with the investigative research purpose.
