Overview

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

5 Tools

Installation

      "command": "uvx",
      "args": ["orcalayer-mcp"]
