## Findings

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

```untrusted-server-text
The server marks "set_prices" 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 name "set_prices" says "set": a word for a change.
```


## Changes things (8)

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

### `all_time_highs`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks which cards in one game are at a record price.
    Returns cards that set an all-time high market price (since February 2024) in the
    last 7 days and still hold it, with the date of the high, in USD.
```

### `all_time_lows`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks which cards in one game are at their lowest price
    or have crashed. Returns cards worth $5+ sitting at their all-time low market price
    after falling at least 50% from their high, with the high and the percent below it,
    in USD.
```

### `card_price`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks what one specific card or sealed product is worth
    today. Returns the latest daily TCGplayer market price and lowest listed price per
    printing (Normal, Holofoil, Reverse Holofoil, 1st Edition...) with the date of the
    price, in USD, plus the page URL. Raw (ungraded) prices only; not an appraisal of
    a particular copy. Needs a product_id from search_cards.
```

### `most_valuable`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks for the most expensive or most valuable cards in
    one game right now. Returns up to 25 singles ranked by today's raw market price
    (USD) with set and printing. Raw prices only, not graded values.
```

### `movers`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks which cards in one game rose or fell the most
    recently. Returns the biggest percentage moves over the last `days` (1 to 90) for
    cards worth $5 or more, with the start and end market price in USD. Describes past
    moves only; not a prediction.
```

### `price_history`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks whether a card's price is going up or down, how it
    moved over a period, or what it was worth on a past date. Returns the daily market
    price per printing for the last `days` days (7 to 1000; history starts February
    2024, later for newer cards) in USD. Past prices only, no forecasts.
```

### `sealed_prices`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks about sealed product prices in one game: booster
    boxes, elite trainer boxes, bundles, packs, tins and cases. Returns today's market
    price (USD) and 30-day percent change per product, most expensive first. For one
    named product, search_cards plus card_price is more direct.
```

### `set_prices`

- The name "set_prices" says "set": 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
Use this when the user asks what a set is worth, what it costs to complete, or
    which cards in one set are the most valuable. Returns the cost to complete the set
    in singles today (one copy of each collector number at its cheapest printing, USD,
    the same figure as the set page), the master set total (every printing we price,
    labeled separately), the 25 most valuable singles and the 10 priciest sealed
    products of the set, plus companion sets
    that ship in the same packs but are catalogued separately (for example a
    Classic Collection or Trainer Gallery subset) with their own totals. Needs a
    group_id from search_cards.
```

## Only reads (3)

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

### `fetch`

- The name "fetch" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this after `search` to read one product: today's market price per printing
    (USD), its move over the last 90 days and the page URL.
```

### `search`

- The name "search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this to look up trading cards or sealed products (Pokemon, One Piece,
    Lorcana, Riftbound, Yu-Gi-Oh, Gundam) by name. Returns up to 10 matches with ids
    to pass to `fetch`.
```

### `search_cards`

- The name "search_cards" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user names a trading card or sealed product and you need its
    TickerMint product_id (required by card_price and price_history) or its set id
    (group_id, required by set_prices). Returns up to 25 matches with name, set,
    collector number, the latest raw market price in USD and the page URL. Covers
    Pokemon, One Piece, Lorcana, Riftbound, Yu-Gi-Oh and Gundam only.
```
