## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "call": a word for a change.
```


## Deletes or cancels (1)

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

### `watch_remove`

- The name "watch_remove" says "remove": a word for removing or ending something.
- The description says "cannot be recovered".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Call this tool to stop tracking one item, by watch id or URL. Its whole price history is deleted and cannot be recovered, so re-adding starts empty. A key matching no watch is refused.
```

## Changes things (7)

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

### `alerts_pending`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Answer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %. Reads stored data only: run watch_refresh first.
```

### `license_activate`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
```

### `price_add_manual`

- The name "price_add_manual" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to store a price you read yourself where a shop blocks fetching: it creates the watch if new and returns the amount and the observation count. An unreadable price is refused. Free: 3 watches.
```

### `price_check`

- The description's first verb is "call": a word for a change.
- 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
Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Reports price, currency, title and confidence, and the change since the last check. It creates no watch.
```

### `price_history`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to list one watch's stored observations, oldest to newest, each with price, currency, source and confidence, plus min and max. Nothing is fetched. Free shows the last 30.
```

### `watch_add`

- The name "watch_add" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Starts tracking it: first observation stored, optional target, re-read by watch_refresh. Free: 3 watches.
```

### `watch_refresh`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The only tool that re-reads prices: it re-fetches one watch or all, appends observations and returns current, previous, min, max, change % and target hits. A page that fails is listed; then read alerts_pending.
```

## Only reads (2)

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

### `license_status`

- The name "license_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
```

### `watch_list`

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

Description, as the server wrote it:

```untrusted-server-text
Show every tracked item with current and previous price, min, max, change %, target, confidence and last check, plus free-tier use. Prices are as of the last watch_refresh, never live; nothing is fetched.
```
