THE RISK

Medium Risk

Why api_ultrade_wallet_add_key needs a policy

This tool creates or adds data (a trading key) to a wallet, making it a Write operation. However, the severity is elevated to 'high' rather than standard 'medium' because adding trading keys to a wallet grants new authorization/authentication capabilities that could enable unauthorized trading if misused by an AI agent.

From the tool's definition 'Add a trading key' modifies wallet configuration by adding a new cryptographic key, which is a persistent data change to authentication/authorization state.

POLICY

How to control api_ultrade_wallet_add_key

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "api_ultrade_wallet_add_key": {
      "limits": [
        {
          "counter": "api_ultrade_wallet_add_key_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

api_ultrade_wallet_add_key stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
