## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (4)

Removes, cancels or revokes something. Claude Code: deny.

### `scheduleit_delete_event`

- The name "scheduleit_delete_event" says "delete": a word for removing or ending something.
- The description says "permanently delete".
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE, DESTRUCTIVE: permanently delete one event or task. It cannot be undone through the API. Only call this when the user clearly asked for this event to be deleted. DELETE /api/events/{id}.

Description, as the server wrote it:

```untrusted-server-text
WRITE: change fields of an existing event; only the fields you pass are changed, the rest stay as they are. Passing resource_ids replaces the whole list of linked resources; an empty string clears notes or a custom field. Changing dates or resources may notify people per the account's notification settings. POST /api/events/{id}.
```

### `scheduleit_update_group`

- The name "scheduleit_update_group" says "update": a word for a change.

### `scheduleit_create_event`

- The name "scheduleit_create_event" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
WRITE: create a new event (booking, shift, job or task) in the Schedule It account, optionally linked to resources. It becomes visible to everyone with access to the schedule, and Schedule It may notify the linked resources according to the account's own notification settings. Confirm the title, dates and resources with the user first. POST /api/events.
```

### `scheduleit_create_group`

```

## Only reads (8)

Looks things up and changes nothing. Claude Code: allow.

### `scheduleit_get_event`

- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One event or task by id with ALL its fields (title, dates, linked resources, notes, completion, priority, custom fields). GET /api/events/{id}.
```

### `scheduleit_get_group`

- The name "scheduleit_get_group" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
One resource group by id with ALL its fields. GET /api/groups/{id}.
```

### `scheduleit_get_resource`

- The name "scheduleit_get_resource" says "get": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.

- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List scheduled events and tasks (bookings, shifts, jobs). Without date_from/date_to Schedule It uses its default date range. Schedule It returns only a short summary of each event unless you name the fields you want: pass `fields` such as id,title,date_start,date_end,owner,notes,completed,priority,custom1 (get_event returns ALL fields of one event). `owner` holds the ids of the resources (people, rooms, equipment) the event is linked to. There is no paging: the reply holds up to `limit` events (default 100), so narrow with the filters instead. Do not call this repeatedly to watch for changes (use modified_after to fetch only what changed). GET /api/events.
```

### `scheduleit_list_groups`

- The name "scheduleit_list_groups" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

List resource groups (the categories resources are organised in, e.g. Staff, Rooms, Vehicles). Pass `fields` (e.g. id,name) for more than the short summary. GET /api/groups.
```

### `scheduleit_list_label_groups`

- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List label groups (the categories that labels are organised in). Pass `fields` (e.g. id,name) for more than the short summary. GET /api/labelgroups.
```

### `scheduleit_list_labels`

- The name "scheduleit_list_labels" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List the labels that can be put on events (for example Confirmed, Urgent). Pass `fields` (e.g. id,name) for more than the short summary. GET /api/labels.
```

### `scheduleit_list_resources`

- The name "scheduleit_list_resources" says "list": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List resources: the people, rooms, equipment or vehicles that events are scheduled against. Schedule It returns only a short summary unless you pass `fields` (for example id,name,email,data1; get_resource returns ALL fields of one). Resources belong to groups (`owner` = group ids). There is no paging; the reply holds up to `limit` resources (default 100). GET /api/resources.
```
