THE RISK

Medium Risk

Why kaspa_generate_mnemonic needs a policy

Generating a mnemonic phrase creates new, persistent cryptographic key material that will be stored and used for wallet operations. While not destructive or financial in itself, it is a write operation that produces data used to control financial assets on the Kaspa blockchain.

From the tool's definition Tool description states it 'Generate[s] a new mnemonic phrase for wallet creation' - the verb 'generate' indicates creation of data (a mnemonic seed phrase) that will be used to establish a wallet.

POLICY

How to control kaspa_generate_mnemonic

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

policy.json

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

kaspa_generate_mnemonic 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
