## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

    "name": "update_operator",

## Why update_operator is rated Medium

This tool modifies user profile data (email, display name) reversibly. It does not delete data (so not Destructive), does not move money directly (so not Financial), and does not execute arbitrary code or external operations (so not Execute). The 'REQUIRES OPERATOR KEY' restriction mitigates risk but does not change the fundamental category.

From the tool's own definition: "Tool description states 'Update operator profile: set your email...and/or display name.' The words 'Update' and 'set' indicate data modification. The mention of email verification and promo eligibility shows this creates reversible state changes."

## Use case

AI agents use update_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.
