Get top position holders for a specific market. Shows who holds the biggest positions and their PnL.
AI agents call get_market_positions to retrieve information from Limitless MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_market_positions is a pure read operation that retrieves historical position and PnL data from blockchain subgraphs. It has no side effects, does not execute code or transactions, and does not modify state. The blast radius of misuse is minimal — an agent querying this tool cannot cause harm beyond potentially learning market participant information that is already public on-chain.
