THE RISK

Critical Risk

Why wallet_abortAction needs a policy

Aborting a transaction is an irreversible cancellation of that pending action. Once aborted, the transaction cannot be recovered or re-submitted; the operation permanently discards the prepared transaction. While it releases inputs back to spendable state (which could be seen as reversible from a funds perspective), the transaction itself is irreversibly destroyed, fitting the Destructive category.

From the tool's definition Aborts a pending (nosend or unsigned) transaction, releasing consumed inputs back to spendable state.

POLICY

How to control wallet_abortAction

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

policy.json

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

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