## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `price_history`

- 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
Daily price history of a specific product across stores: today's lowest price, the range in recent days, and whether today's price is low compared with what it actually cost before (not with a store's 'was' price).
```

## Only reads (1)

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

### `find_best_options`

- The name "find_best_options" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find the best real options to buy a product, ranked only by what is best for the buyer (never by who pays). Returns store, price, shipping, when the price was checked, why each option ranks where it does, and a buy link. Works for any product sold online in the US; stores are added in more categories every week (today: fragrance and beauty). If a category is not compared yet, it says so instead of guessing.
```

## Claude Code permissions

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

```json

  "permissions": {
    "allow": [
      "mcp__bidxon__find_best_options"
    ],
    "ask": [
      "mcp__bidxon__price_history"
    ],
    "deny": []
  }
}
```
