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.

MCP tools · 21 exposed · ~2,207 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
typestringSymbology (code128, qr, datamatrix, ean13, upca, pdf417...)

No output schema declared.

No examples provided.

barcode_verify ~94

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

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
limitintegerMax jobs to return (default 50)

No output schema declared.

No examples provided.

bulk_status ~76

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

No output schema declared.

No examples provided.

bulk_submit ~170

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
dpmmintegerPrint density (default 8)
height_innumberLabel height, inches
outputstringOutput format (default zpl)
rowsarrayyesOne object per label: placeholder name -> value
width_innumberLabel 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
indexintegerLabel 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
ozetobjectyes

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
indexintegerLabel 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

ozetobjectyes

No examples provided.

explain_zpl ~139

Full health report for a ZPL label: sectioned findings (syntax, size/DPI, orientation, barcodes, fonts, graphics memory, job behaviour) with an honest score — sections that cannot be assessed say so and are excluded from the score.

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

No output schema declared.

No examples provided.

image_to_zpl ~131

Convert an image (PNG, JPEG, BMP or GIF, max 200 KB) to a ZPL ^GF graphic command. Returns the ZPL plus measured dimensions and the physical print size at the chosen density. PDF input is REST-only (/v1/graphics).

NameTypeReqDescription
ditherbooleanDither instead of hard threshold (photos)
dpmmintegerTarget printer density
image_base64stringyesBase64-encoded image bytes
wrapbooleanWrap 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

puanlarobjectyesPer-language score

No examples provided.

template_get ~79

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

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
categorystringFilter by category
searchstringSubstring 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

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.

ozetobjectyes

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
localestringLanguage 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 ~137

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).

NameTypeReqDescription
dpmmintegerPrinter density (8 = 203 dpi)
height_innumberLabel height, inches
indexintegerLabel index in the stream
width_innumberLabel width, inches
zplstringyesZPL source (^XA...^XZ)

No output schema declared.

No examples provided.

zpl_validate ~138

Lint ZPL code and return structured diagnostics: unknown commands, missing ^FS, out-of-range parameters, fields outside the label boundary. Run this before zpl_preview when generating ZPL.

NameTypeReqDescription
dpmmintegerPrinter density (8 = 203 dpi). The boundary check measures against it — pass the real value.
height_innumberLabel height in inches. Same as width_in: the boundary check depends on it.
width_innumberLabel width in inches. Fields outside it are reported, so a wrong size makes that finding wrong.

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 85 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 21 tools: zpl_preview, zpl_validate, zpl_command_help, barcode_png, language_detect, and 16 more. Their descriptions and schemas cost roughly 2,207 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 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
