## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (4)

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

### `upper_assign_drivers`

- The name "upper_assign_drivers" says "assign": a word for a change.
- 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: assign one or more drivers (ids from upper_list_drivers) to a route, replacing the route's drivers. Every id must be an active driver on the team. If the route was already optimized it is reset to unoptimized (needs_optimization: true), so run upper_optimize_route again. POST /ext-assign-drivers.
```

### `upper_optimize_route`

- The description's first verb is "write": a word for a change.
- 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: start optimizing a route's stop order. The route needs at least one stop and one assigned driver (upper_assign_drivers). It runs asynchronously: this returns status pending and a queue_id, then poll upper_get_optimization_status. If a job is already running, that job is returned. POST /ext-optimize-route.
```

### `upper_update_route`

- The name "upper_update_route" says "update": a word for a change.
- 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: change settings of an existing route (name, date, optimize_for, units, pickup_settings, service_time). Only the fields you pass change. POST /ext-update-route.
```

### `upper_update_stop`

- The name "upper_update_stop" says "update": a word for a change.
- 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: change an existing stop; only the fields you pass change. A new address is re-geocoded (city/state/zipcode you pass with it are ignored); city/state/zipcode apply only without an address. Passing route_id moves the stop to that route. Editing a stop on an optimized route flags the route for re-optimization; stops on an active route cannot be edited. POST /ext-update-stop.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `upper_create_route`

- The name "upper_create_route" 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, empty route (name, date, optimization preference, units, pickup sequencing, service time). Omitted settings fall back to the account's defaults. Returns the new route_id; add stops with upper_create_stop. Calling it twice creates two routes. POST /ext-create-route.
```

### `upper_create_stop`

- The name "upper_create_stop" 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.
- Tag outbound: The input takes a destination (input.phone): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
WRITE: create a stop. The address is geocoded by Upper. Pass route_id to put it on a route (the route must not be active/in progress; an optimized route is flagged for re-optimization); omit it for an unscheduled stop. Calling it twice creates two stops. POST /ext-create-stop.
```

### `upper_share_route_to_drivers`

- The description's first verb is "write": 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: push a route to the drivers' mobile app NOW, which sends each driver a notification. Without driver_ids the route's assigned drivers are used; with them, every id must be an active driver on the team. Sending twice notifies twice. Confirm with the user before calling. POST /ext-share-to-driver.
```

## Only reads (5)

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

### `upper_get_capacity_fields`

- The name "upper_get_capacity_fields" 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
The workspace's five capacity-field slots (capacity1 - capacity5: label, unit, enabled) used for load planning. GET /ext-get-capacity-fields.
```

### `upper_get_custom_fields`

- The name "upper_get_custom_fields" 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
The workspace's five stop custom-field slots (custom1 - custom5: type, label, enabled, required) and which are enabled. Needs the Custom fields feature in the Upper plan. GET /ext-get-custom-fields.
```

### `upper_get_optimization_status`

- The name "upper_get_optimization_status" 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
Check whether a route is optimized: status is optimized, pending (still running) or not_optimized, plus the queue_id of the last job. Poll this after upper_optimize_route. GET /ext-optimization-status.
```

### `upper_list_drivers`

- The name "upper_list_drivers" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "email": it reads mail.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "list" and "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
List the active drivers on the Upper team that owns the API token: id, name, email and phone. Use the ids with upper_assign_drivers and upper_share_route_to_drivers. GET /ext-get-drivers.
```

### `upper_list_stops`

- The name "upper_list_stops" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "contact": it reads contacts.
- 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 team's stops in optimized order: address, coordinates, contact, time window, duration, status, route_id and custom ids. Pass route_id for one route (optionally scheduled=true/false); pass unscheduled=true (without route_id) for stops not on any route; with no filter all active stops are returned. Upper has no paging, so this tool pages locally: `limit` stops (default 100, max 500) starting at `offset`; the reply says if more remain (truncated, next_offset). GET /ext-get-stops.
```
