Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

Changes things 2Claude Code: ask
  • match_intentClassify a visitor message and return the next public URL.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
    Classify a visitor message and return the next public URL. Order lookup, punch balances, and hiring are not guest-order conversions.
  • understand_siteWhat Straws Soda is, where the shop is, and what this server will not do.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

    Why it is in this group

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

    What it can reach

    • untrusted-inputThe description's first sentence says "return" and "url": it reads web pages, which anyone can write.

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 outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
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.

Remote posture

  • 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.strawssoda.com/api/mcp: tools/list returned 5 tools to an anonymous client, including understand_site (write), match_intent (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 straws-site https://www.strawssoda.com/api/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__straws-site__get_location",
      "mcp__straws-site__list_menu",
      "mcp__straws-site__recommend_path"
    ],
    "ask": [
      "mcp__straws-site__understand_site",
      "mcp__straws-site__match_intent"
    ],
    "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 straws-site. Review it before you use it.
