Claude Code: deny. ### `delete_qr_code` - The name "delete_qr_code" says "delete": a word for removing or ending something. - The description says "Permanently delete". Description, as the server wrote it: ```untrusted-server-text Permanently delete a QR code and its scan history. This action cannot be undone. To prevent accidental or injected deletions, you MUST supply confirm_title — the exact title of the code as returned by get_qr_code or list_qr_codes. If the title does not match the stored record, the deletion is refused. Always call get_qr_code or list_qr_codes first to retrieve the exact title before calling this tool. Requires authentication. ``` ## Changes things (3) Creates or changes something that can be changed back. Claude Code: ask. ### `create_qr_code` - The name "create_qr_code" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a new QR code. Authenticated users (API key required) get a permanent short URL that can be retargeted at any time without reprinting the physical QR image — limits are set by the account plan. Anonymous users receive a one-time data URI image that is not stored and cannot be updated. On success the result is a pre-formatted markdown table — display it exactly as received, do not reformat or summarise. ``` ### `request_api_key` - The name "request_api_key" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text Get a free API token — no account or email required. The token gives you up to 5 QR codes that can be updated at any time. IMPORTANT LIFETIME WARNING: the token expires after 90 days, and QR codes are permanently deleted ~90 days after that (~180 days total). To keep codes alive permanently, claim a free account at https://qrverloz.com/claim — this must be done before the token expires. Save the returned token: it is shown only once. Add it to your MCP client config under Authorization: Bearer, then call create_qr_code. ``` ### `update_qr_target` - The name "update_qr_target" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Change the destination URL of a QR code without touching the printed image. Print once, redirect anywhere — forever. Accepts either the internal qr_code_id or the short_code from the redirect URL. On success the result is a pre-formatted markdown table — display it exactly as received, do not reformat or summarise. Requires authentication. ``` ## Only reads (4) Looks things up and changes nothing. Claude Code: allow. ### `get_account_info` - The name "get_account_info" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get your account details: current plan, QR code usage, and which features are available. Use this before create_qr_code to check remaining capacity, or to confirm which features are active on your plan. Requires authentication. ``` ### `get_qr_code` - The name "get_qr_code" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Look up a single QR code by its internal ID or short code. Returns a pre-formatted markdown table with fields: Title, ID, Short Code, Short URL, Destination, Status, Created, QR Code Link. Display the table exactly as received — do not reformat or summarise. Requires authentication. ``` ### `get_qr_scans` - The name "get_qr_scans" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get the total lifetime scan count for a QR code. Returns a pre-formatted markdown table with fields: Title, ID, Short Code, Short URL, Destination, Status, Created, QR Code Link, Total Scans. Display the table exactly as received — do not reformat or summarise. Requires authentication. ``` ### `list_qr_codes` - The name "list_qr_codes" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List all QR codes in your account. Returns one pre-formatted markdown table per QR code with fields: Title, ID, Short Code, Short URL, Destination, Status, Created, QR Code Link. Display each table exactly as received — do not reformat or summarise. Requires authentication. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `qrverloz`: ```json { "permissions": { "allow": [ "mcp__qrverloz__get_qr_code", "mcp__qrverloz__list_qr_codes", "mcp__qrverloz__get_qr_scans", "mcp__qrverloz__get_account_info" ], "ask": [ "mcp__qrverloz__create_qr_code", "mcp__qrverloz__update_qr_target", "mcp__qrverloz__request_api_key" ], "deny": [ "mcp__qrverloz__delete_qr_code" ] } } ```
