Over the last week it answered 98.6% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 21

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

zpl

zpl_command_help

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.

zpl_compatibility

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.

zpl_preview

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).

zpl_validate

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.

bulk

bulk_list

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

bulk_status

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.

bulk_submit

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).

barcode

barcode_png

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.

barcode_verify

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.

cpcl

cpcl_preview

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.

cpcl_validate

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.

epl

epl_preview

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.

epl_validate

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.

template

template_get

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).

template_list

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.

tspl

tspl_preview

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.

tspl_validate

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.

convert

convert_zpl_dpi

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.

explain

explain_zpl

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.

image

image_to_zpl

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).

language

language_detect

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.

Labelixa — questions

Answers built from our own checks of this server.

What can Labelixa do?

It exposes 21 tools, read directly from the server on our last check. Among them: barcode_png, barcode_verify, bulk_list, bulk_status, bulk_submit, convert_zpl_dpi and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Labelixa mostly used for?

Its tools cluster around zpl, bulk and template. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Labelixa working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 90 checks got a reply (94.4%), average response time 371 ms. The bar chart above shows every period we have measured.

How do I connect Labelixa?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Labelixa need an API key?

No. Labelixa completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Labelixa?

It answers our handshake in 371 ms on average, which is faster than 43% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Labelixa?

The npm package labelixa-mcp was installed 431 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Labelixa open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
