Category Design and Media
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 759 tokens (~253/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
generate_barcode Generate barcode ~328
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.
| Name | Type | Req | Description |
|---|---|---|---|
| caption | string | – | Optional human-readable text drawn under the symbol. Defaults to the value itself. |
| errorCorrection | string | – | QR error-correction level. Higher levels survive more damage but produce a denser symbol. Ignored by linear formats. |
| format | string | – | Output encoding. "svg" returns XML markup; "data-uri" returns a ready-to-embed data: URL. |
| height | number | – | Symbol height in pixels (linear formats mainly). |
| showText | boolean | – | Draw the human-readable caption under the symbol. |
| type | string | yes | Barcode symbology, e.g. "Qrcode", "Ean13", "Code128", "Datamatrix", "Pdf417", "gs1-128". |
| value | string | yes | The data to encode — a URL, product number, tracking code, phone number, Wi-Fi string, etc. |
No output schema declared.
No examples provided.
get_barcode_type Get barcode type details ~119
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.
| Name | Type | Req | Description |
|---|---|---|---|
| type | string | yes | Barcode symbology to look up, e.g. "Qrcode", "Ean13", "gs1-128", "pdf417". |
No output schema declared.
No examples provided.
list_barcode_types List barcode types ~137
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").
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Restrict to one structural class of symbology. |
| family | string | – | Case-insensitive substring match on the family name, e.g. "Code 128", "2D", "EAN". |
No output schema declared.
No examples provided.
How do I install the Barcode Generator MCP server?
Barcode Generator is a hosted endpoint at https://www.barcodegen.net/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Barcode Generator MCP server?
Barcode Generator is an MCP server listed in the public MCP registry as net.barcodegen/barcode-generator. Generate barcodes and QR codes in 35 symbologies: QR, Data Matrix, PDF417, EAN-13, Code 128, more. This page covers its hosted endpoint (https://www.barcodegen.net/mcp).
Is the Barcode Generator MCP server safe to use?
Barcode Generator scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Barcode Generator MCP server expose?
Barcode Generator exposes 3 tools: generate_barcode, list_barcode_types, get_barcode_type. Their descriptions and schemas cost roughly 584 tokens of context every time the server is loaded.
Does the Barcode Generator MCP server require authentication?
No. We connected to Barcode Generator without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Barcode Generator MCP server still maintained?
Barcode Generator is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
