MOST DANGEROUS TOOLS

Critical Risk

The most dangerous CasualMarket tools

Financial · Critical buy_taiwan_stock Even though the server description mentions 'simulated trading,' the tool name 'buy_taiwan_stock' strongly implies a financial transaction — purchasing stock. Financial · Critical sell_taiwan_stock The tool name explicitly indicates selling Taiwan stocks.

2 of CasualMarket's 23 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control CasualMarket

PolicyLayer is an MCP gateway — it sits between your AI agents and CasualMarket, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

{
  "buy_taiwan_stock": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Cap read operations

{
  "check_taiwan_trading_day": {
    "limits": [
      {
        "counter": "check_taiwan_trading_day_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
