  "jsonrpc": "2.0",

## Why register_operator is rated Medium

This tool creates new operator accounts and generates sensitive credentials (API key, recovery code) that establish persistent state. While account registration itself is reversible (accounts can theoretically be deleted), the creation of cryptographic credentials and the establishment of financial/identity state in a Bitcoin Lightning wallet system makes this a Write operation with high severity.

From the tool's own definition: "Tool description states 'Register a new operator account' and 'Returns API key and recovery code.' These are account creation operations that irreversibly create persistent credentials and state."

## Use case

AI agents use register_operator to create or update resources in Lightning Wallet, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lightning Wallet environment.
