## Findings

- **warn** Annotations that disagree with the tool in `identify_charge` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "identify_charge" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "identify_charge" says "charge": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `identify_charge`

- The name "identify_charge" says "charge": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Which subscription is this charge? For requests like "what is this APPLE.COM/BILL charge?", "I see AMZN Digital on my statement", "what is DD *DOORDASH DASHPASS?". Returns the likely service, or for Apple, Amazon, Google and Microsoft the few it could be and where to check, or match: purchase when it looks like a one-off order (marketplace, a ride, a restaurant through a delivery app). Then call get_cancel_steps.
```

## Only reads (3)

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

### `get_cancel_reminder`

- The name "get_cancel_reminder" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Calendar reminder for the last safe day to cancel. Returns a calendar file (.ics) with an all-day event on the cancel-by day, the steps and the official link, with alerts at 9am the day before and 9am on the day. Nothing is stored. get_cancel_steps gives this link as add_to_calendar whenever renews_on is given and the day hasn't passed.
```

### `get_cancel_steps`

- The name "get_cancel_steps" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How to cancel one subscription. For requests like "how do I cancel Netflix?", "cancel my Planet Fitness membership", "how do I leave Sky?", "cancel my PureGym", "what's the cheapest way to keep Spotify?", "stop my Audible". Returns the official page, steps, catches and a cheaper option. UK answers add region ("UK") and uk_rules; a US-only service asked about from the UK has region "US only".
```

### `list_services`

- The name "list_services" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Every subscription Cancel My Sub covers. For requests like "which subscriptions can you help me cancel?" or "what gyms do you know?". Also returns the current status of the FTC click-to-cancel rule and the UK rules (uk_rules)
```
