## Exfil surface

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

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

## Findings

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

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

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


## Changes things (4)

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

### `deals`

- 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
Today's deals: products whose cheapest listing is well under their own 30-day average low (or, for new products, under today's typical price). Optional category key from list_categories.
```

### `price_moves`

- The name "price_moves" says "move": 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
Biggest price moves over the last week across all tracked products (typical asking price, then vs now), falling and rising.
```

### `price_per_unit`

- 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
Cheapest price per unit, best first: per GB/TB for storage and RAM, per GB of VRAM for GPUs, per battery, per ounce, per foot of cable and so on. category = a key from list_categories (e.g. 'storage', 'ram', 'gpus', 'Batteries', 'Coffee & tea'). Optional condition for eBay categories: new, used or refurb.
```

### `used_vs_new`

- 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
How much buying used or refurbished saves vs new, typical price vs typical price, for a category key from list_categories (not collectibles).
```

## Only reads (3)

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

### `get_price`

- The name "get_price" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Today's price summary for one sharpest.ai product page (a URL from search_prices): lowest and median asking price, listing count, 30-day low, high and change.
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
Categories sharpest.ai tracks, with the keys the other tools take: eBay product categories (GPUs, storage, RAM, phones, cameras, cards...) and per-unit staple groups (batteries, coffee, cables...).
```

### `search_prices`

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

Description, as the server wrote it:

```untrusted-server-text
Find current prices for a product on sharpest.ai: GPUs, CPUs, RAM, SSDs, phones, laptops, cameras, consoles, Pokemon and other trading cards, LEGO, and everyday staples priced per unit (batteries, coffee, cables...). Returns today's lowest and median US eBay Buy It Now asking price (item + shipping, USD; not sold prices) or, for staples, the cheapest price per unit across Amazon and eBay, with a link to the product page.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `sharpest`:

```json
{
  "permissions": {
    "allow": [
      "mcp__sharpest__search_prices",
      "mcp__sharpest__list_categories"
    ],
    "ask": [
      "mcp__sharpest__get_price",
      "mcp__sharpest__price_per_unit",
      "mcp__sharpest__deals",
      "mcp__sharpest__used_vs_new",
      "mcp__sharpest__price_moves"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__sharpest__get_price`: untrusted-input, outbound
