OrcaLayer MCP — Polymarket Whale Analytics

OrcaLayer MCP Server

Polymarket whale tracking and smart-money analytics MCP server. A thin stdio wrapper over the orcalayer Python SDK.

What it does

• Filtered leaderboard — top smart-money whales with airdrop-farmers and market-makers excluded by default
• Hedge detection — flags wallets holding YES + NO on same market (market-maker pattern, not directional alpha)
• NegRisk correction — multi-outcome markets correctly weighted (no double-counting)
• Unique ISW Ukraine module — overlay of Institute for the Study of War frontline data on territorial prediction markets (50+ cities mapped)
• Open methodology — full classification rules published at orcalayer.com/methodology
