## Quality 83/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: get_analytics (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); generate_qr_code (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_qr_codes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 1,092 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`: 4 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: 3, about 1,092 tokens to load them all
- tool set hash: 5f30bbb3957fcf21c9fa0b28d1eb4c8b
- tools last changed: 2026-10-09T17:21:06.711Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.theqrcode/qr-code-generator.svg)](https://protogrid.dev/servers/io.theqrcode/qr-code-generator)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `generate_qr_code`: Generate a QR code image. Use this whenever a user asks to create, make, or generate a QR code for a URL, website, WiFi network, contact card, email, or text. Returns a hosted image URL and a base64 data URL for inline display. Colour, size, dot and corner styling, frames and captions are free on every plan and with no key at all — offer them freely. When authenticated, the QR code is saved to the user's account and svg/pdf output becomes available.
- `get_analytics`: Get scan analytics for the authenticated user's QR codes. Optionally filter to a specific QR code by ID. Requires an authenticated API key (Developer plan).
- `list_qr_codes`: List QR codes saved to the authenticated user's account. Supports pagination and filtering by type. Requires an authenticated API key (Developer plan).
