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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. 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
Schema Quality & AI Usability74
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 3065 tokens (~133/item across 23 items; 23 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 Management100
  • No destabilizing schema changes in the last 30 days.Pass
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
  • Structured output schemas are declared (26% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 23 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 24 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 23 exposed · ~2,942 tokens

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 →

Tool Tokens
barcode_png ~97

Generate a single barcode as a PNG image (Code 128, QR, DataMatrix, EAN-13, UPC-A, PDF417 and more). For a full label with text and layout, write ZPL and use zpl_preview instead.

NameTypeReqDescription
datastringyesData to encode
typestring–Symbology (code128, qr, datamatrix, ean13, upca, pdf417...)

No output schema declared.

No examples provided.

barcode_verify ~109

Decode barcodes from a photo or scan of a PRINTED label (PNG, JPEG, BMP or GIF) and report what a software decoder reads back. Honest by design: 'read' does not guarantee every handheld scanner will read it, and 'not read' does not condemn the label (photo angle/focus matter) — the response says so.

NameTypeReqDescription
image_base64stringyesBase64-encoded image bytes. A data:image/...;base64, prefix and line breaks are accepted.

No output schema declared.

No examples provided.

bulk_list ~54

List your recent bulk jobs (id, state, error class, timestamps), newest first. Useful to recover a lost job id; details via bulk_status.

NameTypeReqDescription
limitinteger–Max jobs to return (default 50)

No output schema declared.

No examples provided.

bulk_status ~87

Status of one bulk job you own: state, attempt count and — when finished — the summary with produced count and per-row failures (row number + reason; failed rows never block the rest). Finished outputs stay downloadable for 7 days via the REST endpoint the response names.

NameTypeReqDescription
job_idstringyesJob id from bulk_submit (32 hex characters; the dashed UUID form is accepted)

No output schema declared.

No examples provided.

bulk_submit ~188

Submit a bulk label production job: one ZPL template with {{variable}} placeholders plus data rows (one object per label). Requires an API key whose plan includes bulk jobs. Quota is charged UPFRONT, one operation per row, and failed rows are not refunded; rows per job are capped by plan. Returns the job id — check bulk_status (small jobs usually finish within seconds).

NameTypeReqDescription
dpmminteger–Print density (default 8)
height_innumber–Label height, inches
outputstring–Output format (default zpl)
rowsarrayyesOne object per label: placeholder name -> value, e.g. [{"name": "Ada", "sku": "A-1"}]
width_innumber–Label width, inches
zplstringyesZPL template with {{name}} placeholders

No output schema declared.

No examples provided.

convert_zpl_dpi ~131

Rescale ZPL between printer resolutions (203/300/600 DPI): coordinates, fonts, barcode module width and label size are scaled. Embedded ^GF/~DG image data is NOT scaled; the response says so instead of silently passing it through.

NameTypeReqDescription
source_dpiintegeryesResolution the ZPL was written for, in DPI (not dpmm: 203 DPI = 8 dpmm).
target_dpiintegeryesResolution to rescale to, in DPI. Equal to source_dpi means no scaling.
zplstringyesRaw ZPL code

No output schema declared.

No examples provided.

cpcl_preview ~109

Render CPCL label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the CPCL manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may contain several, each ended by `PRINT`); pass `index` to render a different one.

NameTypeReqDescription
cpclstringyesRaw CPCL code
indexinteger–Label index in the stream

No output schema declared.

No examples provided.

cpcl_validate ~87

Lint CPCL label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the CPCL manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before cpcl_preview; if you are not sure which language the code is, call language_detect first.

NameTypeReqDescription
cpclstringyesRaw CPCL code
NameTypeReqDescription
diagnosticsarrayyes–
summaryobjectyes–

No examples provided.

epl_preview ~113

Render EPL/EPL2 label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the EPL2 manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may contain several, each ended by `P`); pass `index` to render a different one.

NameTypeReqDescription
eplstringyesRaw EPL/EPL2 code
indexinteger–Label index in the stream

No output schema declared.

No examples provided.

epl_validate ~91

Lint EPL/EPL2 label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the EPL2 manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before epl_preview; if you are not sure which language the code is, call language_detect first.

NameTypeReqDescription
eplstringyesRaw EPL/EPL2 code
NameTypeReqDescription
diagnosticsarrayyes–
summaryobjectyes–

No examples provided.

explain_zpl ~172

Human-readable health REPORT for a finished ZPL label, with a 0-100 score: sectioned findings (syntax, size/DPI, orientation, barcodes, fonts, graphics memory, job behaviour); sections that cannot be assessed say so and are excluded from the score. Use it to review or explain a label to a person; for a quick pass/fail check while editing, use zpl_validate instead.

NameTypeReqDescription
dpmminteger–Printer density (8 = 203 dpi). The size/DPI section is scored against it — pass the real value.
height_innumber–Label height in inches; same role as width_in.
width_innumber–Label width in inches; fields outside it are reported.
zplstringyesRaw ZPL code

No output schema declared.

No examples provided.

image_to_zpl ~177

Convert an image (PNG, JPEG, BMP, GIF or SVG, max 200 KB) to a ZPL ^GF graphic command. SVG is rasterised at the chosen density from its declared size (mm/in honoured); SVGs with external references or a DTD are rejected. Returns the ZPL plus measured dimensions and the physical print size at the chosen density. PDF input is REST-only (/v1/graphics).

NameTypeReqDescription
ditherboolean–Dither instead of hard threshold (photos)
dpmminteger–Target printer density
image_base64stringyesBase64-encoded image bytes. A data:image/...;base64, prefix and line breaks are accepted.
wrapboolean–Wrap the ^GF in a printable ^XA...^XZ label with ^PW/^LL

No output schema declared.

No examples provided.

language_detect ~68

Detect which printer language raw label code is written in (ZPL, EPL, TSPL or CPCL). Heuristic: returns the language plus a confidence TIER (high/medium/low) and signal codes — not a probability.

NameTypeReqDescription
codestringyesRaw label code to classify
NameTypeReqDescription
confidencestringyesConfidence level
evidencearray––
languagestringyesDetected printer language
mixedboolean–True when the input mixes languages
scoresobjectyesPer-language score

No examples provided.

printer_language_to_zpl ~310

Convert a SATO SBPL, Honeywell (Datamax) DPL or Honeywell (Intermec) IPL label stream to ZPL, so it can be checked with zpl_validate and rendered with zpl_preview. You must name the source language: language_detect does not recognise these three. Real control characters and the manuals' readable notation (<STX>, <ESC>) are both accepted. Commands outside the supported subset (printer settings, RFID, job management, some 2D symbologies) are skipped with a warning, never silently: non-empty `warnings` mean the conversion is not 1:1 and `one_to_one` is false — show the warnings to the user. The output follows each manufacturer's command reference and is not verified on physical printers; check a preview and a test print before production.

NameTypeReqDescription
codestringyesRaw SBPL, DPL or IPL label stream
dpmminteger–Target printer density in dots per mm (8 = 203 dpi)
label_length_mmnumber–DPL only: label length in mm. DPL measures rows from the bottom edge, ZPL from the top; without it (or <STX>c in the stream) 6 inches is assumed and a warning is added.
source_languagestringyesLanguage of `code`: sbpl (SATO), dpl (Datamax / Honeywell) or ipl (Intermec / Honeywell)
NameTypeReqDescription
notestring––
one_to_onebooleanyesTrue only when warnings is empty
source_languagestringyes–
warningsarrayyesEverything not carried over, with the manual page
zplstringyesConverted ZPL, one ^XA...^XZ block per label

No examples provided.

save_label ~179

Save a ZPL label to a Labelixa account so it can be edited, versioned and printed later. With an API key the label is saved immediately and the saved label id is returned. Without a key the label is held for 24 hours and a one-time link is returned: the user opens it, signs in (free account is enough) and the label lands in their account. Nothing else is stored for anonymous calls.

NameTypeReqDescription
dpmminteger–Print density in dots per mm: 6, 8, 12 or 24 (8 = 203 dpi)
height_innumber–Label height in inches
namestring–Label name (default: 'Label from assistant')
width_innumber–Label width in inches
zplstringyesRaw ZPL code

No output schema declared.

No examples provided.

template_get ~89

Fetch one catalog template: metadata, preview image URL and — for non-premium templates — the ZPL source, ready for zpl_preview. Premium templates return metadata for everyone; their ZPL source requires an API key whose plan includes the premium-template feature (same rule as the website).

NameTypeReqDescription
template_idstringyesTemplate `id` from template_list (the id, not the display name)

No output schema declared.

No examples provided.

template_list ~79

List Labelixa's first-party label template catalog: id, English name, category, size/density and tags. Read-only product content (no tenant data). Fetch one with template_get; render its ZPL with zpl_preview.

NameTypeReqDescription
categorystring–Filter by category
searchstring–Substring match on id/tags

No output schema declared.

No examples provided.

tspl_preview ~117

Render TSPL/TSPL2 label code and return a PNG preview. The preview assumes 203 dpi and is an interpretation of the TSPL manual covering a core command subset — no physical printer validation. `labels` in the response is the TOTAL number of labels the stream prints (a stream may contain several, each ended by `PRINT`); pass `index` to render a different one.

NameTypeReqDescription
indexinteger–Label index in the stream
tsplstringyesRaw TSPL/TSPL2 code

No output schema declared.

No examples provided.

tspl_validate ~96

Lint TSPL/TSPL2 label code and return positioned findings with severity as JSON. Checks the command set Labelixa implements from the TSPL2 manual — a clean result is not a guarantee that a specific printer accepts the job. Run this before tspl_preview; if you are not sure which language the code is, call language_detect first.

NameTypeReqDescription

No examples provided.

zpl_command_help ~104

Explain a single ZPL command: syntax, parameters with types/ranges/options, a fragment example and whether the Labelixa renderer draws it. Data comes from the same catalog that powers the public command reference pages.

NameTypeReqDescription
commandstringyesZPL command code, e.g. FO, ^BC, ~DG
localestring–Language for the human-readable fields (name and descriptions). Command codes, syntax strings, examples and parameter names never change.

No output schema declared.

No examples provided.

zpl_compatibility ~97

Compatibility RISK analysis of ZPL code against a specific printer model, given as manufacturer/model (e.g. 'zebra/zd421'). NOT an emulator and never says 'it works': reports the model's language posture with evidence level and size-rule findings.

NameTypeReqDescription
modelstringyesPrinter model slug, manufacturer/model, e.g. zebra/zd421
zplstringyesRaw ZPL code

No output schema declared.

No examples provided.

zpl_preview ~183

Render ZPL label code and return the label as a PNG image. Use this to SEE what ZPL output looks like — LLMs can write ZPL but cannot otherwise verify the visual result. One call renders one label (use `index` to pick a label from a multi-label stream). The result also carries an 'Open this label in the Labelixa editor' link the user can click to edit, save or share the label.

NameTypeReqDescription
dpmminteger–Printer density (8 = 203 dpi)
height_innumber–Label height, inches
indexinteger–Label index in the stream
width_innumber–Label width, inches
zplstringyesZPL source, non-empty, from ^XA to ^XZ. Send real line breaks, not the two characters \n.

No output schema declared.

No examples provided.

zpl_validate ~205

Pass/fail lint for ZPL — machine-readable diagnostics with line/column, code and severity: unknown commands, missing ^FS, out-of-range parameters, fields outside the label. Fast; run it before zpl_preview whenever you generate or edit ZPL. For a human-readable report with a score, use explain_zpl instead.

NameTypeReqDescription
dpmminteger–Printer density in dots per mm: 6, 8, 12 or 24 (8 = 203 dpi, 12 = 300 dpi, 24 = 600 dpi). The boundary check measures against it — pass the real value.
height_innumber–Label height in inches. Same as width_in: the boundary check depends on it.
width_innumber–Label width in inches. Fields outside it are reported, so a wrong size makes that finding wrong.

Install

How do I install the Labelixa MCP server?

Labelixa is a hosted endpoint at https://api.labelixa.com/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.

Common questions

What is the Labelixa MCP server?

Labelixa is an MCP server listed in the public MCP registry as com.labelixa/zpl. Thermal label MCP server: render, validate, debug and convert ZPL, EPL, TSPL and CPCL labels. This page covers its hosted endpoint (https://api.labelixa.com/mcp).

Is the Labelixa MCP server safe to use?

Labelixa scores 87 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 Labelixa MCP server expose?

Labelixa exposes 23 tools: zpl_preview, zpl_validate, zpl_command_help, barcode_png, language_detect, and 18 more. Their descriptions and schemas cost roughly 2,942 tokens of context every time the server is loaded.

Does the Labelixa MCP server require authentication?

No. We connected to Labelixa without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Labelixa MCP server still maintained?

Labelixa is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What did VerifyMCP test on the Labelixa MCP server?

VerifyMCP ran 13 checks on Labelixa, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
