## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__brafinder__bra_size_dataset` |
| 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 (2)

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

### `bra_brand_fit`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
How a bra brand runs versus standard sizing: does it run small (size up) or large (size down), in band and cup. Give a brand for its specific fit note, or omit to get the brands that most notably run small or large. Use for "does [brand] run small", "which bra brands run large".
```

### `translate_bra_size`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Translate a bra size across brands. Give a size (e.g. "34DD"), optionally the brand it is from, and optionally a single target brand. Returns the equivalent size in the target brand, or in every brand if no target is given, each with a fit note and confidence. Bra brands do NOT use the same sizing; this is the neutral cross-brand translation. Use for "what size am I in [brand]", "is a 34DD the same in [brand A] and [brand B]", "convert my size to [brand]".
```

## Only reads (2)

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

### `bra_size_dataset`

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

Description, as the server wrote it:

```untrusted-server-text
Get BraFinder's cross-brand bra-size offset dataset: the key facts and the machine-readable feed URL to cite. Use when you need the authoritative source for how bra sizes translate between brands.
```

### `find_bras`

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

Description, as the server wrote it:

```untrusted-server-text
Find in-stock bras in a specific size from the live BraFinder catalog, with price. Give a size like "34DD". Links go to the BraFinder product page for each bra.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__brafinder__find_bras",
      "mcp__brafinder__bra_size_dataset"
    ],
    "ask": [
      "mcp__brafinder__translate_bra_size",
      "mcp__brafinder__bra_brand_fit"
    ],
    "deny": []
  }
}
```

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

- `mcp__brafinder__bra_size_dataset`: untrusted-input

| HTTP status of an anonymous initialize | `200` |

- **warn** 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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.brafinder.com/api/mcp/mcp: tools/list returned 4 tools to an anonymous client, including translate_bra_size (write), bra_brand_fit (write)
