## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: request_api_key (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_qr_code (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_qr_code (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,284 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 8, about 1,284 tokens to load them all
- tool set hash: 2721ae0db47d476117a37f0d02afe0ef

## Tools (8)

- `create_qr_code`: 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.
- `delete_qr_code`: 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.
- `get_account_info`: 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`: 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`: 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`: 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.
- `request_api_key`: 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`: 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.
