THE RISK

High Risk

Signing into a trading account triggers an authentication/session operation against an external trading system. This goes beyond a simple read — it initiates an active session that could enable subsequent financial operations. Given the financial trading context (BNB Chain, Sperax Protocol, trading account), a compromised sign-in could expose trading capabilities, making it high severity.

HOW TO CONTROL API_ULTRADE_WALLET_SIGNIN

PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for api_ultrade_wallet_signin:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "api_ultrade_wallet_signin": {
      "limits": [
        {
          "counter": "api_ultrade_wallet_signin_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

api_ultrade_wallet_signin 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.

Create a free account and register BNB Chain MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
