Why secret_key_to_mnemonic needs a policy

This tool performs a read-only transformation of an existing secret key into its mnemonic representation. There are no side effects, no data modification, no external operations triggered, and no irreversible actions. While the data being handled is sensitive (cryptographic secrets), the tool itself only reads and formats the input—it does not execute code, modify blockchain state, delete data, or move funds.

From the tool's definition The tool name 'secret_key_to_mnemonic' and description 'Convert a secret key to a mnemonic' indicate a conversion/translation operation that reads and transforms a cryptographic secret into an alternative representation format.

POLICY

How to control secret_key_to_mnemonic

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 secret_key_to_mnemonic:

policy.json

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

secret_key_to_mnemonic 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.
