# Update User Group

Use the Speak AI MCP server tool `update_user_group` to update a user group's name
and member list.

## What does it do?

Update a user group's name and member list. NOTE: the users array is a FULL
REPLACEMENT, not a delta. Any member id you omit is removed from the group. Fetch
the current members with `list_user_groups` first and send the complete list.

## Parameters

`update_user_group` takes 3 parameters, all of them required.

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `_id` | string | Yes | Group _id to update (from `list_user_groups`) |
| `description` | string | Yes | New group name |
| `users` | array of string | Yes | Full replacement list of member _id strings (omitted users are removed) |
