Tools

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

3 tools

Can't be undone 2Claude Code: ask
  • convert_currencyConvert an amount between currencies using LIVE exchange rates (refreshed every 6h).Can send data outNo findings

    Why it is in this group

    • The name "convert_currency" says "convert": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.

    What it can reach

    • outboundThe input takes a destination (input.to): what the tool writes goes there.
    Description, as the server wrote it
    Convert an amount between currencies using LIVE exchange rates (refreshed every 6h). Use ISO 4217 codes (USD, EUR, ...). This is the tool to use instead of estimating rates from memory.
  • convert_unitsConvert a numeric value between two units of the same category (length, weight, volume, temperature, etc.).Can send data outNo findings

    Why it is in this group

    • The name "convert_units" says "convert": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.

    What it can reach

    • outboundThe input takes a destination (input.to): what the tool writes goes there.
    Description, as the server wrote it
    Convert a numeric value between two units of the same category (length, weight, volume, temperature, etc.). Units resolve by id or symbol (e.g. "cm" or "centimeter"). For currency use convert_currency.
Only reads 1Claude Code: allow
  • list_unitsList every conversion category with its units (id, symbol, name).No findings

    Why it is in this group

    • The name "list_units" says "list": a word for reading.
    Description, as the server wrote it
    List every conversion category with its units (id, symbol, name). Call this to discover the vocabulary before convert_units.

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 untrusted-input.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out2
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.

Install

Pinned to version 1.0.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http toolalize https://toolalize.com/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__toolalize__list_units"
    ],
    "ask": [
      "mcp__toolalize__convert_units",
      "mcp__toolalize__convert_currency"
    ],
    "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 toolalize. Review it before you use it.
