This tool performs a read-only query to retrieve a list of users from a Kommo CRM account. It has no capacity to modify, create, delete, or execute operations. The blast radius is minimal as it only returns informational data about account users.

{
"version": "1",
"default": "deny",
"tools": {
"get_users": {}
}
}get_users is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
