Why mnemonic_from_seed needs a policy

This tool generates a mnemonic phrase from a seed. While it doesn't directly perform a read, write, execute, destructive, or financial operation on external systems, it produces cryptographic key material (mnemonic phrases) that could be used to control crypto wallets and DeFi assets. The operation itself is a local computation/generation, but misuse could lead to exposure of wallet credentials.

POLICY

How to control mnemonic_from_seed

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for mnemonic_from_seed:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mnemonic_from_seed": {
      "limits": [
        {
          "counter": "mnemonic_from_seed_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

mnemonic_from_seed gets a rate cap, and everything else on the server is denied unless you say otherwise.
