## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

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

### `add_to_wishlist`

- The name "add_to_wishlist" says "add": 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
Adds products to a wishlist made earlier, given its edit link or the token at the end of it. A product already on the list keeps its place and takes the new note. A list holds at most 50 products; unknown or unavailable products, and products that no longer fit, are reported and not added. Returns the list's items with their best current prices. The token stops working once the list has been saved to a Plendio account.
```

### `remove_from_wishlist`

- The name "remove_from_wishlist" says "remove": a word for removing or ending something.
- 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
Removes products from a wishlist, given its edit link or the token at the end of it. A product that is not on the list is reported and ignored. Removing a product does not delete the list, even when it becomes empty, and a removed product can be added again. Returns the list's remaining items.
```

## Changes things (1)

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

### `create_wishlist`

- The name "create_wishlist" 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
Creates a shareable wishlist ("ønskeseddel") on Plendio from products a person has picked, for example gifts found with a search, once they want a list to send to family or friends. Takes a title (up to 80 characters), a market and 1 to 50 products by Plendio id, each with an optional note of up to 140 characters. Returns two links, a read-only share link to the list's page on Plendio and a private edit link for changing the list and saving it to a Plendio account, together with the list's items and their best current prices. No login is needed and no personal data is collected. Unknown or unavailable products are reported and not stored. The edit link is a secret: anyone who holds it can change the list. A list that is not viewed or edited for 90 days is deleted. Each request creates a new list.
```

## Only reads (5)

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

### `compare_prices`

- The name "compare_prices" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the shops selling one product, one offer per shop (its best, with a count of its other offers), cheapest first by total price including shipping (price alone where a shop's shipping is unknown), with each amount also converted to the market's currency. Offers that are in stock come first. Out-of-stock offers are left out unless include_out_of_stock is true, and only shops that ship to the market are listed unless include_other_markets is true. The result includes the url of the product's Plendio page.
```

### `get_product`

- The name "get_product" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Returns one product by its Plendio id: specifications, one offer per shop (its best) with price, shipping, total, the same amounts in the market's currency, availability, condition and whether the shop ships to the market, a summary of the product's price history over the last year, and the url of its Plendio page. A product that was merged into another resolves to the current one.
```

### `get_wishlist`

- The name "get_wishlist" says "get": a word for reading.
- Tag private-data: The description's first sentence says "return" and "note": it reads notes.
- Tag untrusted-input: The description's first sentence says "return" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Returns a Plendio wishlist from its share link or share id: its title, its items with notes and best current prices, and the url of each product's Plendio page. Read-only; the edit link is not needed and not accepted. The title and the notes are text written by whoever made the list.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Returns Plendio's product categories with localized names, slugs and product counts: the top level, or the subcategories of parent. The counts are products available in the market.
```

### `search_products`

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

Description, as the server wrote it:

```untrusted-server-text
Search Plendio's product catalogue: free text in Danish, Swedish, German, Norwegian or English ("laptop 32 GB RAM under 12000", "Sony WH-1000XM5", "running shoes women") plus optional filters. Spec words in the query (RAM, storage, screen size, price limits, in stock) are understood the way the Plendio website understands them. Each result has the cheapest current price, the number of shops selling it and the url of its Plendio page. Results are limited to shops that ship to the market unless include_other_markets is true. 24 results per page.
```

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (2 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://plendio.com/mcp: tools/list returned 8 tools to an anonymous client, including add_to_wishlist (destructive), remove_from_wishlist (destructive), create_wishlist (write)
