## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__tangylimes__get_pricing` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__tangylimes__buy_cards` `mcp__tangylimes__get_pricing` `mcp__tangylimes__request_card` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "make_card_link" says "link": a word for a change.
```


## Changes things (3)

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

### `buy_cards`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
Make a Stripe checkout link for packs of 3 cards ($4.99 a pack). The person pays on Stripe; the cards are then added to the account for the email given, and they make each card on tangylimes.com by signing in with that email. Nothing is charged until they pay. Always show the link to the person; never claim the purchase is done.
```

### `make_card_link`

- The name "make_card_link" says "link": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- 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
A link that opens a card on tangylimes.com, ready for the person to add their photo and watch the free preview. Add a discount code to apply it automatically.
```

### `request_card`

- The name "request_card" says "request": 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
Ask the studio to make a card that doesn't exist yet. Leave an email to hear when it's ready.
```

## Only reads (3)

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

### `get_card`

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

Description, as the server wrote it:

```untrusted-server-text
Details for one card by id: title, occasion, headline, how many faces, formats, length, price and links.
```

### `get_pricing`

- The name "get_pricing" says "get": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "email": it reads inbound email, which other people can write.

Description, as the server wrote it:

```untrusted-server-text
Tangy Limes prices: one card, the 3-pack, the custom song, and the first-card email offer. No subscription.
```

### `search_cards`

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

Description, as the server wrote it:

```untrusted-server-text
Find Tangy Limes video greeting cards. Each card is a short music video where real faces from a photo sing an original song. Filter by words (e.g. "dog birthday", "roast", "Paris anniversary"), occasion, and how many faces the card fits.
```
