## Quality 89/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 796 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 5 of the 7 days needed

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

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

- tools: 3, about 796 tokens to load them all
- tool set hash: 08f5f0d3243068b390718b8ed71bcdb5
- badge: [![protogrid quality](https://protogrid.dev/badge/net.barcodegen/barcode-generator.svg)](https://protogrid.dev/servers/net.barcodegen/barcode-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_barcode`: Encode a value into any of 35 barcode and QR symbologies and return the rendered image. Supports QR Code, Data Matrix, PDF417, Aztec, EAN-13, UPC-A, Code 128/39/93, ITF-14 and more. Returns SVG markup by default (or a data: URI when asked), plus a link to the online generator pre-filled with the same value. Use "type" with the canonical name from list_barcode_types; common spellings like "qr" or "code-128" are accepted. Linear formats such as EAN-13 enforce strict charset and length rules and will fail on invalid input.
- `get_barcode_type`: Return the full technical reference for one symbology: character set, data length, check digit rules, X-dimension and quiet-zone guidance, print ratio, magnification, governing standard, inventor and year, typical applications, FAQ, and related formats. Use this to pick a format for a requirement, or to find out why generate_barcode rejected a value.
- `list_barcode_types`: List every symbology this server can generate (35 formats), grouped by family, with a one-line summary and sample data for each. Call this first when you are unsure which "type" to pass to generate_barcode. Optionally narrow by family (e.g. "EAN / UPC", "2D Barcodes") or category ("linear", "stacked", "2d").
