    Why it is in this group

    • The name "find_best_australian_exchange" says "find": a word for reading.
    Description, as the server wrote it
    Compare Australian cryptocurrency exchanges to identify the best estimated buying or selling outcome for a specified asset, AUD trade amount and direction. Use this tool when the user wants to compare exchange prices, fees or estimated value received. For simply finding exchanges that offer a cryptocurrency, use find_where_to_buy_crypto instead. Results are estimates, not guaranteed executable quotes, and no trade is placed. This is a paid data-access tool using XRP on XRPL Mainnet. First call without paymentSignature to receive an x402 v2 payment challenge. An authorised compatible payer must generate the PAYMENT-SIGNATURE for the exact resource and retry with identical inputs. Never supply wallet secrets. This server does not sign or initiate payments. If payment fails or times out, verify settlement before attempting another payment.

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 or outbound.

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 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.

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__cryptobuddy__find_best_australian_exchange",
      "mcp__cryptobuddy__find_where_to_buy_crypto"
    ],
    "ask": [],
    "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 cryptobuddy. Review it before you use it.
