Model Context Protocol (MCP) server for the [OrcaLayer API](https://orcalayer.com) —
Polymarket whale and market analytics inside Claude Desktop and other MCP clients.

It is a thin stdio wrapper over the [`orcalayer`](https://pypi.org/project/orcalayer/)
Python SDK and exposes six tools:

| Tool | What it does | Key |
|---|---|---|
| `leaderboard` | Rank smart-money whales by P&L, win rate or volume | No |
| `wallet_overview` | Wallet profit tracking: profile, P&L and win-rate summary | No |
| `wallet_positions` | A wallet's largest open positions | No |
| `markets` | Track smart money flows: search markets where smart whales are accumulating | No |
| `market_consensus` | Smart-money consensus on one market vs its price (head-count + capital-weighted) | No |
| `whale_alerts` | Real-time alerts on profitable wallets: live feed of smart-whale trades | Premium |

Public tools work anonymously. `whale_alerts` needs a Premium API key
([get one](https://orcalayer.com/pricing)) 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](https://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.

## Resources

Read-only context the model can pull directly — no tool call needed:

| Resource URI | Content |
|---|---|
| `orcalayer://methodology` | How smart money is filtered from farmers, hedgers and market-makers |
| `orcalayer://glossary` | Prediction-markets glossary |
| `orcalayer://api-reference` | OrcaLayer REST API reference (endpoints, auth, rate limits) |

## 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):

```json
{
  "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](https://orcalayer.com/pricing)):

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

Restart Claude Desktop after editing the config.
