Unlock trading operations for real/simulated accounts.
AI agents invoke unlock_trade to trigger actions in Futu Stock MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool unlocks trading capabilities on real or simulated financial accounts. While it doesn't directly move money, it removes a security barrier that gates all subsequent trade execution. Misuse by an AI agent could enable unauthorized trade execution across HK, US, and A-share markets — making it a critical enabler of financial harm.
From the tool's definition Unlock trading operations for real/simulated accounts
Documented attack patterns abuse exactly the kind of access unlock_trade gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Futu Stock MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for unlock_trade:
{
"version": "1",
"default": "deny",
"tools": {
"unlock_trade": {
"limits": [
{
"counter": "unlock_trade_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}unlock_trade stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
