## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `price_card`

- 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
Looks up the current market price of a single TCG card (any of 22+ games: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and more). Returns the best match's price and an affiliate-wrapped TCGplayer product link, plus alternates when the name is ambiguous.
```

### `price_deck`

- 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
Prices a pasted decklist (any TCG: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and 18+ more) and returns a ready-to-buy TCGplayer cart link. Paste the raw decklist text — one card per line, quantity + name, e.g. '4x Lightning Bolt' or '2 Counterspell (7ED)'. Returns a priced table (qty, name, set, unit price, line total), a market-price estimate (full estimate, known-price subtotal, or unknown depending on price coverage), any lines that couldn't be resolved with did-you-mean suggestions, and one affiliate-wrapped buy link.
```

## Only reads (2)

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

### `list_printings`

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

Description, as the server wrote it:

```untrusted-server-text
Lists every known printing of a TCG card (any of 22+ games) — every set it was printed in, with per-finish (nonfoil/foil) prices and treatment tags (border, frame, promo, full art). Use this instead of price_card when the buyer wants to compare printings, find the cheapest version, or find a specific treatment (e.g. borderless, showcase). Returns a `grouping` field: "oracle_id" means the printings are confirmed the exact same card; "normalized_name" is a best-effort name match that can occasionally over- or under-group.
```

### `market_index`

- The description's first verb is "show": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Shows the cross-market price trend for a whole game or a single set — a chain-linked index (base 100) with 7/30/90-day movement, the total market value of one-of-every product, the median price, and how many products are priced. Use this for "how is Pokemon / this set trending" questions, or pass a comma-separated `vs` list to compare up to 3 scopes. This is trend data across a set, NOT a single card's price — use price_card or list_printings for one card.
```
