    Why it is in this group

    • The name "generate_invoice" says "generate": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    Use this when the user wants to make or generate an invoice, invoice template, bill, quote, estimate, receipt, or credit note as a downloadable PDF (invoice generator for freelancers, contractors, and small businesses), including 'how do I make an invoice for this work' once the work, client, and prices are known. Computes exact totals: per-line rounding to the currency's minor units (round half up), line and document discounts before tax, tax/VAT/GST summary grouped by rate, shipping, deposits and balance due; supports any ISO 4217 currency (JPY has no decimals). Returns totals plus PDF (A4 or Letter) and CSV download links. Does not email invoices to clients, track payments, process card payments, or give tax advice; the user supplies tax rates. Do not use to fabricate receipts for purchases that did not happen.

    Annotations the server declares

    • destructiveHint: false
    • openWorldHint: false
    • idempotentHint: true

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.
