MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Alpha Arcade tools

Financial · Critical amend_order This tool modifies active financial orders on a prediction market, adjusting price, quantity, and collateral. Financial · Critical create_limit_order This tool directly commits financial obligations on-chain by placing a limit order on a prediction market and locking real ALGO collateral. Financial · Critical create_market_order This tool directly executes financial transactions on-chain by placing market orders on prediction markets, locking real cryptocurrency (ALGO) as collateral. Financial · High merge_shares This tool performs an on-chain financial operation that converts prediction market outcome tokens back into USDC stablecoin, directly moving/converting financial assets on the Algorand blockchain.

8 of Alpha Arcade's 20 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Alpha Arcade

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

Block financial tools by default

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

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

Deny destructive operations

{
  "cancel_order": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Cap read operations

{
  "get_agent_guide": {
    "limits": [
      {
        "counter": "get_agent_guide_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Point your MCP client (Claude, Cursor, anything) at your gateway URL.
