- hygiene: 80
- liveness: 100
- freshness: 100

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 75/100 (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: 100 (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
- pass `tools.annotations`: 11 of 11 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,039 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 11 tool changes in 30 days
- fail `stability.rug_pull`: 5 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 11, about 2,039 tokens to load them all
- tool set hash: bdc32206a71104ea7d8b1a6bcfa5c3fd
- tools last changed: 2026-10-04T22:38:01.727Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.danieldedaniel/qrtracer.svg)](https://protogrid.dev/servers/io.github.danieldedaniel/qrtracer)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-04 `simulate_scan` changed (description, inputSchema, annotations)
  - before: Dry-run a routing program against a fake scan context.
  - after: Dry-run a routing program against a sample scan context. Does not create a scan or change a code.
- 2026-10-04 `set_routing` changed (description, inputSchema, annotations) **meaning changed**
  - before: Compile plain English into a routing program and save it on a claimed code.
  - after: 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.
- 2026-10-04 `check_qr_link` added
  - 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.
- 2026-10-04 `render_qr` changed (description, inputSchema, annotations) **meaning changed**
  - before: Return PNG/SVG render URLs for a code.
  - after: 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.
- 2026-10-04 `compare_qr_codes` added
  - 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.
- 2026-10-04 `get_analytics` changed (description, inputSchema, annotations) **meaning changed**
  - before: Read scan counts for a claimed code.
  - after: 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.
- 2026-10-04 `update_destination` changed (description, inputSchema, annotations) **meaning changed**
  - before: Update a claimed QR destination URL.
  - after: 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.
- 2026-10-04 `get_qr_code` added
  - Inspect an owned QR code, destination, design, latest stored link health and revision. Read before updating.
- 2026-10-04 `list_qr_codes` added
  - Find only your owned QR codes, with label search and stable cursor pagination.
- 2026-10-04 `get_account` added
  - Read the connected account's plan and available capabilities. Does not include email or billing details.

## Packages

_none_

## Tools (11)

- `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.
- `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_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.
- `get_account`: Read the connected account's plan and available capabilities. Does not include email or billing details.
- `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.
