orcalayer-mcp

PyPI MIT License MCP MCP Badge Glama MCP orcalayer-mcp MCP server

Model Context Protocol (MCP) server for the OrcaLayer API — Polymarket whale and market analytics inside Claude Desktop and other MCP clients.

It is a thin stdio wrapper over the orcalayer Python SDK and exposes five tools:

Tool

What it does

Key

leaderboard

Rank smart-money whales by P&L, win rate or volume

No

wallet_overview

A wallet's profile and performance summary

No

wallet_positions

A wallet's largest open positions

No

markets

Search markets where smart whales are clustering

No

whale_alerts

Live feed of recent smart-whale trades

Premium

Public tools work anonymously. whale_alerts needs a Premium API key (get one) supplied via the ORCALAYER_API_KEY environment variable.

New (2026-07-22): the Premium SSE stream (/api/public/v1/live/trades) now carries settlement_type (MINT / MERGE / COMPLEMENTARY / null) on every event — live-derived settlement mechanics, shadow-verified 100.000% accurate on MINT/MERGE. It describes how the match settled, not trader intent (~80% of all fills settle as MINT; null = honest refusal, not "not a mint"). Details: the orcalayer://api-reference resource or orcalayer.com/docs/api.

Prompts

Ready-to-use prompts for common analytics scenarios:

Prompt

What it does

analyze_wallet

Full wallet analysis — smart money or farmer?

find_divergence

Markets where smart money disagrees with the current price

hedge_check

Whether a wallet's profit was real alpha or a hedge structure

territorial_markets_review

Ukraine territorial markets with ISW frontline overlay

In Claude Desktop, pick a prompt from the prompt menu (the + / slash-command picker) — each one orchestrates the tools above for you.

Use with Claude Desktop

Add this to your claude_desktop_config.json (%APPDATA%\Claude\claude_desktop_config.json on Windows, ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "orcalayer": {
      "command": "uvx",
      "args": ["orcalayer-mcp"]
    }
  }
}

The public tools work as-is. For the Premium whale_alerts tool, add your API key (get one):

{
  "mcpServers": {
    "orcalayer": {
      "command": "uvx",
      "args": ["orcalayer-mcp"],
      "env": { "ORCALAYER_API_KEY": "sk_orca_your_key_here" }
    }
  }
}

Restart Claude Desktop after editing the config.
