Claude Code: ask. ### `invoice_payment_qr` - The name "invoice_payment_qr" says "payment": a word that usually means money moves, which cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Call this tool for a SEPA payment QR from just an amount and reference: IBAN and name are read from the shared business profile, never asked for; pass invoice_id instead to take the amount from an invoice. ``` ### `qr_payment_sepa` - The name "qr_payment_sepa" says "payment": a word that usually means money moves, which cannot be taken back. - The input carries an amount (input.amount) and a currency, so it moves money. Description, as the server wrote it: ```untrusted-server-text Call this tool for an EPC069-12 payment QR a euro banking app can scan. Amount and reference are enough: the beneficiary IBAN and name default to the shared business profile, never asked for. ``` ## Changes things (6) Creates or changes something that can be changed back. Claude Code: ask. ### `barcode_batch` - The description's first verb is "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this tool to draw many barcodes or QR codes at once from a list of rows, each with its own value and file name. Every row comes back as its own download link valid for one hour. Pro; the free tier does one code per call. ``` ### `barcode_create` - The name "barcode_create" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this tool to draw a linear barcode (code128, ean13, ean8, upca) as SVG, or PNG to out_path. A short EAN or UPC gets its check digit computed; a wrong one is refused, never redrawn. qr_create makes QR codes. ``` ### `license_activate` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Turn Pro on for this connection with key, an MCPL1.. issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it. ``` ### `qr_create` - The name "qr_create" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this tool to turn text or a URL into a QR code: SVG inline, or a PNG at a pixel size to out_path (Pro). Returns version, module grid and payload size. Free: 20 codes a month on this server. ``` ### `qr_vcard` - The description's first verb is "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this tool to make a QR code that adds a contact when scanned (vCard 3.0). For your own card pass nothing: name, phone, email and address default to the shared business profile, never asked for. ``` ### `qr_wifi` - The description's first verb is "call": a word for a change. Description, as the server wrote it: ```untrusted-server-text Call this tool to make a QR code that joins a WiFi network when scanned: ssid, password and auth type, written to out_path or returned as SVG. Free: 20 codes a month. qr_create takes plain text or a URL. ``` ## Only reads (2) Looks things up and changes nothing. Claude Code: allow. ### `code_list` - The name "code_list" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the codes this server generated, newest first, with what each carried and where it went, plus how much of the free 20 a month is used. Filter by kind. It reads the register, not the files. ``` ### `license_status` - The name "license_status" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `barcode-qr-code-sepa-payment-ean13`: ```json { "permissions": { "allow": [ "mcp__barcode-qr-code-sepa-payment-ean13__license_status", "mcp__barcode-qr-code-sepa-payment-ean13__code_list" ], "ask": [ "mcp__barcode-qr-code-sepa-payment-ean13__license_activate", "mcp__barcode-qr-code-sepa-payment-ean13__qr_create", "mcp__barcode-qr-code-sepa-payment-ean13__qr_wifi", "mcp__barcode-qr-code-sepa-payment-ean13__qr_vcard", "mcp__barcode-qr-code-sepa-payment-ean13__qr_payment_sepa", "mcp__barcode-qr-code-sepa-payment-ean13__invoice_payment_qr", "mcp__barcode-qr-code-sepa-payment-ean13__barcode_create", "mcp__barcode-qr-code-sepa-payment-ean13__barcode_batch" ], "deny": [] } } ```
