Changes things 2Claude Code: ask
  • bra_brand_fitHow a bra brand runs versus standard sizing: does it run small (size up) or large (size down), in band and cup.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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_sizeTranslate a bra size across brands.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    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 2Claude Code: allow
  • bra_size_datasetGet BraFinder's cross-brand bra-size offset dataset: the key facts and the machine-readable feed URL to cite.Reads text others writeNo findings

    Why it is in this group

    • The description's first verb is "get": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "get" and "url": it reads web pages, which anyone can write.
    Description, as the server wrote it
    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_brasFind in-stock bras in a specific size from the live BraFinder catalog, with price.No findings

    Why it is in this group

    • The name "find_bras" says "find": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

  • WarnThe whole server

    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.

    Matched text

    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)

    What this check looks for

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http brafinder https://www.brafinder.com/api/mcp/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__brafinder__find_bras",
      "mcp__brafinder__bra_size_dataset"
    ],
    "ask": [
      "mcp__brafinder__translate_bra_size",
      "mcp__brafinder__bra_brand_fit"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as brafinder. Review it before you use it.
