## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 79/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2330 tokens (~110/item across 21 items; 21 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 90/100
  - Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (24% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 21 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 22 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (21)

### `zpl_preview` (~137 tokens)

Render ZPL label

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).

Input parameters:

- `dpmm` (integer): Printer density (8 = 203 dpi)
- `height_in` (number): Label height, inches
- `index` (integer): Label index in the stream
- `width_in` (number): Label width, inches
- `zpl` (string, required): ZPL source (^XA...^XZ)

### `zpl_validate` (~138 tokens)

Validate ZPL

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.

Input parameters:

- `dpmm` (integer): Printer density (8 = 203 dpi). The boundary check measures against it — pass the real value.
- `height_in` (number): Label height in inches. Same as width_in: the boundary check depends on it.
- `width_in` (number): Label width in inches. Fields outside it are reported, so a wrong size makes that finding wrong.
- `zpl` (string, required): ZPL source

Output parameters:

- `alanlar` (array)
- `diagnostics` (array)
- `ozet` (object)
- `rfid` (array)

### `zpl_command_help` (~104 tokens)

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.

Input parameters:

- `command` (string, required): ZPL command code, e.g. FO, ^BC, ~DG
- `locale` (string): Language for the human-readable fields (name and descriptions). Command codes, syntax strings, examples and parameter names never change.

### `barcode_png` (~97 tokens)

Generate 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.

Input parameters:

- `data` (string, required): Data to encode
- `type` (string): Symbology (code128, qr, datamatrix, ean13, upca, pdf417...)

### `language_detect` (~68 tokens)

Detect printer language

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.

Input parameters:

- `code` (string, required): Raw label code to classify

Output parameters:

- `dil` (string): Detected printer language
- `guven` (string): Confidence level
- `kanitlar` (array)
- `karma` (boolean): True when the input mixes languages
- `puanlar` (object): Per-language score

### `epl_validate` (~91 tokens)

Validate EPL

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.

Input parameters:

- `epl` (string, required): Raw EPL/EPL2 code

Output parameters:

- `diagnostics` (array)
- `ozet` (object)

### `tspl_validate` (~96 tokens)

Validate TSPL

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.

Input parameters:

- `tspl` (string, required): Raw TSPL/TSPL2 code

Output parameters:

- `diagnostics` (array)
- `ozet` (object)

### `cpcl_validate` (~87 tokens)

Validate CPCL

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.

Input parameters:

- `cpcl` (string, required): Raw CPCL code

Output parameters:

- `diagnostics` (array)
- `ozet` (object)

### `explain_zpl` (~139 tokens)

Explain ZPL health report

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.

Input parameters:

- `dpmm` (integer): Printer density (8 = 203 dpi). The size/DPI section is scored against it — pass the real value.
- `height_in` (number): Label height in inches; same role as width_in.
- `width_in` (number): Label width in inches; fields outside it are reported.
- `zpl` (string, required): Raw ZPL code

### `convert_zpl_dpi` (~131 tokens)

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.

Input parameters:

- `source_dpi` (integer, required): Resolution the ZPL was written for, in DPI (not dpmm: 203 DPI = 8 dpmm).
- `target_dpi` (integer, required): Resolution to rescale to, in DPI. Equal to source_dpi means no scaling.
- `zpl` (string, required): Raw ZPL code

### `template_list` (~79 tokens)

List label templates

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.

Input parameters:

- `category` (string): Filter by category
- `search` (string): Substring match on id/tags

### `template_get` (~79 tokens)

Get label template

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).

Input parameters:

- `template_id` (string, required): Template id from template_list

### `epl_preview` (~113 tokens)

Render EPL label

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.

Input parameters:

- `epl` (string, required): Raw EPL/EPL2 code
- `index` (integer): Label index in the stream

### `tspl_preview` (~117 tokens)

Render TSPL label

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.

Input parameters:

- `index` (integer): Label index in the stream
- `tspl` (string, required): Raw TSPL/TSPL2 code

### `cpcl_preview` (~109 tokens)

Render CPCL label

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.

Input parameters:

- `cpcl` (string, required): Raw CPCL code
- `index` (integer): Label index in the stream

### `image_to_zpl` (~131 tokens)

Convert 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).

Input parameters:

- `dither` (boolean): Dither instead of hard threshold (photos)
- `dpmm` (integer): Target printer density
- `image_base64` (string, required): Base64-encoded image bytes
- `wrap` (boolean): Wrap the ^GF in a printable ^XA...^XZ label with ^PW/^LL

### `barcode_verify` (~94 tokens)

Read back barcodes from an image

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.

Input parameters:

- `image_base64` (string, required): Base64-encoded image bytes

### `zpl_compatibility` (~97 tokens)

Check printer 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.

Input parameters:

- `model` (string, required): Printer model slug, manufacturer/model, e.g. zebra/zd421
- `zpl` (string, required): Raw ZPL code

### `bulk_submit` (~170 tokens)

Submit bulk label job

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).

Input parameters:

- `dpmm` (integer): Print density (default 8)
- `height_in` (number): Label height, inches
- `output` (string): Output format (default zpl)
- `rows` (array, required): One object per label: placeholder name -> value
- `width_in` (number): Label width, inches
- `zpl` (string, required): ZPL template with {{name}} placeholders

### `bulk_status` (~76 tokens)

Bulk job 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.

Input parameters:

- `job_id` (string, required): Job id from bulk_submit

### `bulk_list` (~54 tokens)

List bulk jobs

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

Input parameters:

- `limit` (integer): Max jobs to return (default 50)

## 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.
