## MCP tools (11)

### `zpl_preview` (~132 tokens)

Render ZPL label code to a PNG image via the Labelixa API. This is a SERVER-SIDE render for inspection — it is not a guarantee of how a specific physical printer will output the label.

Input parameters:

- `dpmm` (integer): Printer density in dots per mm (6, 8, 12 or 24)
- `height_in` (number): Label height in inches
- `index` (integer): Which label to render when the stream contains several
- `width_in` (number): Label width in inches
- `zpl` (string, required): Raw ZPL code (^XA ... ^XZ)

### `zpl_validate` (~109 tokens)

Lint/validate ZPL and return the structured diagnostics report (unknown commands, parameter range errors, layout overflow, etc.) as JSON. Pass the real label size — checks depend on it.

Input parameters:

- `dpmm` (integer): Printer density in dots per mm (6, 8, 12 or 24)
- `height_in` (number): Label height in inches
- `width_in` (number): Label width in inches
- `zpl` (string, required): Raw ZPL code

### `barcode_generate` (~87 tokens)

Generate a standalone barcode (SVG text or PNG image). Supported types include code128, code39, ean13, upca, upce, itf14, msi, qrcode, datamatrix, pdf417.

Input parameters:

- `data` (string, required): Data to encode
- `format` (string)
- `type` (string, required): Barcode type, e.g. code128

### `language_detect` (~68 tokens)

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

### `epl_validate` (~50 tokens)

Lint/validate EPL/EPL2 label code and return the structured diagnostics report (findings with positions and severity) as JSON.

Input parameters:

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

### `tspl_validate` (~54 tokens)

Lint/validate TSPL/TSPL2 label code and return the structured diagnostics report (findings with positions and severity) as JSON.

Input parameters:

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

### `cpcl_validate` (~46 tokens)

Lint/validate CPCL label code and return the structured diagnostics report (findings with positions and severity) as JSON.

Input parameters:

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

### `zpl_compatibility` (~102 tokens)

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, size-rule findings and the scope of our preview.

Input parameters:

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

### `zpl_command_help` (~108 tokens)

Look up one ZPL command in the maintained catalog: name, syntax, parameters (types, ranges, defaults) and whether the preview engine actually renders it — printer-side commands are honestly marked as not rendered.

Input parameters:

- `command` (string, required): Command code with or without prefix, e.g. ^PO, BC, ~DG
- `locale` (string): Language for the name and descriptions (default English). Command codes, syntax strings, examples and parameter names are protocol and never change.

### `convert_zpl_dpi` (~113 tokens)

Rescale ZPL coordinates between printer resolutions (203/300/600 dpi). Embedded ^GF/~DG bitmap data is NOT rescaled — when present, a Warnings block precedes the output instead of silently passing.

Input parameters:

- `source` (integer): Source resolution in dpi (152, 203, 300 or 600)
- `target` (integer): Target resolution in dpi (152, 203, 300 or 600)
- `zpl` (string, required): Raw ZPL code to convert

### `explain_zpl` (~155 tokens)

Full sectioned health report for a ZPL label (syntax, size/DPI, orientation, barcodes, fonts, memory) with an honest score: only assessable sections count, the rest say 'not assessed'. Pass the real label size — findings depend on it.

Input parameters:

- `dpmm` (integer): Printer density in dots per mm (6, 8, 12 or 24)
- `height_in` (number): Label height in inches
- `model` (string): Optional printer model as manufacturer/model (e.g. zebra/zd421) to add a model-compatibility section
- `width_in` (number): Label width in inches
- `zpl` (string, required): Raw ZPL code

## 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 npm package (labelixa-mcp).

### Is the Labelixa MCP server safe to use?

Labelixa scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. 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 11 tools: zpl_preview, zpl_validate, barcode_generate, language_detect, epl_validate, and 6 more. Their descriptions and schemas cost roughly 1,024 tokens of context every time the server is loaded.

### 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.

### What licence is the Labelixa MCP server under?

Labelixa declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
