Available tools 11

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

account

get_account

Read the connected account's plan and available capabilities. Does not include email or billing details.

analytics

get_analytics

Read aggregate recorded human scans for one owned code. Default period is 28 days; history follows the current plan. Scans are not conversions or unique people.

code

get_qr_code

Inspect an owned QR code, destination, design, latest stored link health and revision. Read before updating.

codes

list_qr_codes

Find only your owned QR codes, with label search and stable cursor pagination.

compare

compare_qr_codes

Compare aggregate human scan counts for 2 to 10 owned QR codes over the same period. Do not infer conversion rates without separate conversion data.

create

create_qr

Create a dynamic QR code for a public HTTP(S) destination. Supply a UUID request_key to safely retry authenticated creation. Anonymous creation is limited; ALWAYS show its returned claim_url to the user. Account creation uses existing plan limits.

destination

update_destination

Change an owned QR destination without changing its printed redirect URL. Confirm the intended destination with the user. Supply expected_revision from get_qr_code; conflict means read again before retrying.

link

check_qr_link

Check a public QR destination's current HTTP reachability, redirect chain and known general provider policies. Cannot determine exact expiry, account state or destination safety.

render

render_qr

Preview and download an owned QR as PNG, or eligible SVG. Returns a short-lived download URL; do not expose private connection tokens. Existing anonymous PNG URLs remain supported.

routing

set_routing

Legacy Programmable tool: compile a plain-language routing prompt or save a valid supplied routing program on an owned code. Version conflicts require reading again.

simulate

simulate_scan

Dry-run a routing program against a sample scan context. Does not create a scan or change a code.

QRtracer — questions

Answers built from our own checks of this server.

What can QRtracer do?

It exposes 11 tools, read directly from the server on our last check. Among them: check_qr_link, compare_qr_codes, create_qr, get_account, get_analytics, get_qr_code and 5 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is QRtracer working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 188 ms. The bar chart above shows every period we have measured.

The registry lists QRtracer as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect QRtracer?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does QRtracer need an API key?

No. QRtracer completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.
