MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Lemonade Stand MCP Server tools

Financial · Medium buy_supplies The tool purchases supplies, which constitutes a financial transaction within the game simulation. Execute · Low next_day While the tool is part of a game simulation (low actual risk), it executes a game action whose effects depend on the current game state. Execute · Low sell_lemonade This tool executes a business simulation action with side effects (inventory changes, revenue generation, game state progression) that cannot be predicted in advance and depend on dynamic factors like weather and pricing Execute · Low start_game This tool triggers initialization of a game environment, which is an external operation execution.

5 of Lemonade Stand MCP Server's 5 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Lemonade Stand MCP Server

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

Block financial tools by default

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

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

Rate limit write operations

{
  "set_price": {
    "limits": [
      {
        "counter": "set_price_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.
