## 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__used-prices__check_ebay_listing` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__used-prices__check_ebay_listing` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_ebay_listing`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Judge whether an eBay listing is a good price: compares its delivered price with what the same model actually sold for recently (great / fair / above typical / overpriced, and % vs the sold median), and lists cheaper listings that ship to the buyer.
```

## Only reads (2)

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

### `get_used_price`

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

Description, as the server wrote it:

```untrusted-server-text
What a used PC part actually sells for on eBay: sold-price median and p25-p75 range (EUR) over the last 30 and 90 days, for one market or all seven pooled.
```

### `list_tracked_models`

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

Description, as the server wrote it:

```untrusted-server-text
The PC part models pcprice.watch tracks, with their IDs, optionally filtered by part type.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `used-prices`:

```json
{
  "permissions": {
    "allow": [
      "mcp__used-prices__get_used_price",
      "mcp__used-prices__list_tracked_models"
    ],
    "ask": [
      "mcp__used-prices__check_ebay_listing"
    ],
    "deny": []
  }
}
```
