Why make_app_delete_txn needs a policy

The tool creates a transaction to delete an application, which is an irreversible operation that destroys data or application state. Combined with the DeFi/crypto context where transactions have real financial consequences on blockchain, this poses critical risk if an AI agent executes it without proper authorization or understanding.

From the tool's definition Tool name contains 'delete' ("make_app_delete_txn") and description states "Create an application delete transaction". This irreversibly removes an application.

POLICY

How to control make_app_delete_txn

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 make_app_delete_txn:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "make_app_delete_txn"
  ]
}

make_app_delete_txn disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
