About
Polymarket smart-money analytics: whale leaderboard, wallet P&L, market consensus, live alerts
Security Report
This is a well-structured MCP server for the OrcaLayer Polymarket analytics API. It properly handles authentication (optional for public tools, Premium API key via environment variable), implements defensive error handling with API key scrubbing, and delegates all business logic to an upstream SDK. Permissions are appropriate for the category (network_http, env_vars) and match the server's purpose. Minor issues include loose exception handling and absence of input validation on user-supplied market identifiers, but these are low-severity and do not create exploitable vulnerabilities. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

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 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) supplied via the
ORCALAYER_API_KEY environment variable.
New (2026-07-22): the Premium SSE stream (
/api/public/v1/live/trades) now carriessettlement_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: theorcalayer://api-referenceresource 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.
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):
{
"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.
