Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (20)

`bulk_create_dynamic_qr`	Create up to 200 dynamic QR codes at once. Requires an OpenQR API key.
`clear_subdomain`	Release the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
`create_dynamic_qr`	Create an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.
`create_folder`	Create a folder to organise codes. Requires an OpenQR API key.
`create_link_alias`	Create an extra short link (link alias) that resolves where one of your dynamic codes points: share a different slug per channel while the QR keeps its own slug, so QR scans and link clicks are counted separately. Free accounts have no alias allowance; Pro includes 10. Requires an OpenQR API key.
`create_static_qr`	Save a static QR code to your library from structured fields: wifi, contact (vCard), email, SMS, WhatsApp, location, text, phone or URL. Static codes bake the content into the code itself — no short link, no scan analytics, not editable later. Render the returned payload with generate_qr. Requires an OpenQR API key.
`create_theme`	Save a reusable style theme. `style` is a QR style object (fgColor, bgColor, dotType, cornerSquareType, etc.). Requires an OpenQR API key.
`delete_dynamic_qr`	Permanently delete a dynamic QR code. The short link stops working. Requires an OpenQR API key.
`delete_folder`	Delete a folder (its codes are un-filed, not deleted). Requires an OpenQR API key.
`delete_theme`	Delete a saved theme. Codes already styled with it keep their look. Requires an OpenQR API key.
`generate_qr`	Generate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.
`get_dynamic_qr`	Get the full details of one of your QR codes by id: destination, short link, label, type, tags, folder, status and created date. Requires an OpenQR API key.
`get_scans`	Get scan statistics for a dynamic QR code. Requires an OpenQR API key.
`get_subdomain`	Show the branded subdomain on this account ({name}.oqr.to). Reports whether it is currently suspended — a suspended subdomain redirects to the plain short link instead of serving, which happens when a Pro plan lapses. Requires an OpenQR API key.
`list_dynamic_qr`	List your dynamic (editable) QR codes — id, short URL, destination, label and status. Requires an OpenQR API key.
`list_folders`	List your folders (id and name). Requires an OpenQR API key.
`list_link_aliases`	List the link aliases of one dynamic code. Requires an OpenQR API key.
`list_themes`	List your saved style themes (id, name) — apply one by passing its id or name as `theme` to generate/create/update tools. Requires an OpenQR API key.
`set_subdomain`	Claim or change the branded subdomain so codes also resolve at {name}.oqr.to. Pro only. Codes keep working on the plain short link either way, so changing this never breaks anything already printed. Requires an OpenQR API key.
`update_dynamic_qr`	Edit a dynamic QR code: change its destination, label, custom short link (slug), tags or folder. Pass only the fields you want to change. Requires an OpenQR API key.
