README

orcalayer-mcp

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.

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": "ol_your_key" }
    }
  }
}

Restart Claude Desktop after editing the config.
