5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Can't be undone 1Claude Code: ask
  • calculate_sales_taxWork out sales tax exactly, in whole minor units.1 finding

    Why it is in this group

    • The input carries an amount (input.amount) and a currency, so it moves money.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

      The server marks "calculate_sales_tax" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

      Matched text

      annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input carries an amount (input.amount) and a currency, so it moves money.

      What this check looks for
    Description, as the server wrote it
    Work out sales tax exactly, in whole minor units. mode "add": amount is the price before tax. mode "extract": amount already includes the tax, and the net price and the tax inside it are returned. rate is a percentage like "8.25". Money is a decimal string. Returns net, tax and gross as decimal strings rounded to the currency's decimals (default 2). Free. Make receipts only for lawful purposes, such as replacing a lost receipt, bookkeeping, testing or design mockups. Using a receipt to deceive anyone, including for refunds, expense claims or proof of purchase, is prohibited.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Work out a tip and split a bill between people, in whole cents. round "none" rounds the tip to the cent; "up-total" rounds the total up to the next whole unit; "up-each" rounds each person's share up to the next whole unit and the total becomes shares times people. Returns tip, total and per_person as decimal strings. Free. Make receipts only for lawful purposes, such as replacing a lost receipt, bookkeeping, testing or design mockups.

PUT the raw bytes to upload_url with a Content-Length header, then pass file_id as make_receipt's logo.file_id. Free.

Returns url, expires_at and text, what a reader will decode (including the check digit). Free within a daily quota counted in documents (see start.md).

    Why it is in this group

    What it can reach

    • outboundThe input takes a URL (input.logo.url): a request to a URL can carry data to whoever runs it.
    Description, as the server wrote it
    Make a receipt file from a template, with your own items, and get a 24-hour download link. Call list_templates for a slug first. Set accept_terms to true. items is required (1 to 200): name, qty and unit_price as decimal strings like "4.50", never numbers; subtotal, tax and total are worked out for you. Every other field you leave out (store name and address, date, currency, tax, payment, discounts, extra_lines, messages, barcode) uses the template's sample value, so pass an empty array to clear discounts, extra_lines or messages. format is png (default), jpeg or pdf. An optional logo goes on top: PNG, JPEG or SVG up to 2 MB (a PNG or JPEG at most 2 megapixels, for example 1600×1250; resize a bigger one first), as file_id (from create_upload), url or data_base64; it replaces the template's logo, and header.logo "none" removes the template's logo. Returns url, expires_at, the delivered image size in pixels (for a PDF, the page at 1x), the totals as formatted strings, and notes for anything that was left out or cut. Free within a daily quota counted in documents (see start.md). Make receipts only for lawful purposes, such as replacing a lost receipt, bookkeeping, testing or design mockups. Using a receipt to deceive anyone, including for refunds, expense claims or proof of purchase, is prohibited.

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.

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 out1
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.

Findings

Matches of fixed checks, with the text they matched.

1 warn

    What this check looks for

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

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__receipt-maker__list_templates"

    "ask": [

      "mcp__receipt-maker__calculate_tip",
      "mcp__receipt-maker__create_upload"
    ],
    "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 receipt-maker. Review it before you use it.
