## Quality 94/100 (new)

### 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: 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`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 345 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

## Tools (1)

- `create_static_qr_code`: Create a static QR code image (PNG or SVG) from text, a URL, WiFi credentials, a vCard or any other payload up to 1000 bytes. The payload is encoded directly in the pattern, so the code works forever, but it cannot be edited or tracked after printing. For an editable code with scan analytics, the user needs a dynamic QR code from qrcode.io (15-day free trial, no card).
