Why api_ultrade_wallet_key_message needs a policy

The tool generates a message from trading key data, which is a read/compute operation with no apparent side effects. It does not submit transactions, move funds, or modify state. However, the description is sparse, and in a trading context 'generating a message' could be a signing step preceding financial operations. Confidence is moderate due to limited description detail.

How to control api_ultrade_wallet_key_message

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_key_message:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "api_ultrade_wallet_key_message": {}
  }
}

api_ultrade_wallet_key_message is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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