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
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
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
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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 →
barcode_png Generate 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.
| Name | Type | Req | Description |
|---|---|---|---|
| data | string | yes | Data to encode |
| type | string | – | Symbology (code128, qr, datamatrix, ean13, upca, pdf417...) |
No output schema declared.
No examples provided.
barcode_verify Read back barcodes from an image ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| image_base64 | string | yes | Base64-encoded image bytes. A data:image/...;base64, prefix and line breaks are accepted. |
No output schema declared.
No examples provided.
bulk_list List bulk jobs ~54
List your recent bulk jobs (id, state, error class, timestamps), newest first. Useful to recover a lost job id; details via bulk_status.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max jobs to return (default 50) |
No output schema declared.
No examples provided.
bulk_status Bulk job 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.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | Job id from bulk_submit (32 hex characters; the dashed UUID form is accepted) |
No output schema declared.
No examples provided.
bulk_submit Submit bulk label job ~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).
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | Print density (default 8) |
| height_in | number | – | Label height, inches |
| output | string | – | Output format (default zpl) |
| rows | array | yes | One object per label: placeholder name -> value, e.g. [{"name": "Ada", "sku": "A-1"}] |
| width_in | number | – | Label width, inches |
| zpl | string | yes | ZPL template with {{name}} placeholders |
No output schema declared.
No examples provided.
convert_zpl_dpi 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.
| Name | Type | Req | Description |
|---|---|---|---|
| source_dpi | integer | yes | Resolution the ZPL was written for, in DPI (not dpmm: 203 DPI = 8 dpmm). |
| target_dpi | integer | yes | Resolution to rescale to, in DPI. Equal to source_dpi means no scaling. |
| zpl | string | yes | Raw ZPL code |
No output schema declared.
No examples provided.
cpcl_preview Render CPCL label ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| cpcl | string | yes | Raw CPCL code |
| index | integer | – | Label index in the stream |
No output schema declared.
No examples provided.
cpcl_validate Validate CPCL ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| cpcl | string | yes | Raw CPCL code |
| Name | Type | Req | Description |
|---|---|---|---|
| diagnostics | array | yes | – |
| summary | object | yes | – |
No examples provided.
epl_preview Render EPL label ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| epl | string | yes | Raw EPL/EPL2 code |
| index | integer | – | Label index in the stream |
No output schema declared.
No examples provided.
epl_validate Validate EPL ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| epl | string | yes | Raw EPL/EPL2 code |
| Name | Type | Req | Description |
|---|---|---|---|
| diagnostics | array | yes | – |
| summary | object | yes | – |
No examples provided.
explain_zpl Explain ZPL health report ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Raw ZPL code |
No output schema declared.
No examples provided.
image_to_zpl Convert 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).
| Name | Type | Req | Description |
|---|---|---|---|
| dither | boolean | – | Dither instead of hard threshold (photos) |
| dpmm | integer | – | Target printer density |
| image_base64 | string | yes | Base64-encoded image bytes. A data:image/...;base64, prefix and line breaks are accepted. |
| wrap | boolean | – | Wrap the ^GF in a printable ^XA...^XZ label with ^PW/^LL |
No output schema declared.
No examples provided.
language_detect Detect printer language ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Raw label code to classify |
| Name | Type | Req | Description |
|---|---|---|---|
| confidence | string | yes | Confidence level |
| evidence | array | – | – |
| language | string | yes | Detected printer language |
| mixed | boolean | – | True when the input mixes languages |
| scores | object | yes | Per-language score |
No examples provided.
printer_language_to_zpl Convert 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.
| Name | Type | Req | Description |
|---|---|---|---|
| code | string | yes | Raw SBPL, DPL or IPL label stream |
| dpmm | integer | – | Target printer density in dots per mm (8 = 203 dpi) |
| label_length_mm | number | – | 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_language | string | yes | Language of `code`: sbpl (SATO), dpl (Datamax / Honeywell) or ipl (Intermec / Honeywell) |
| Name | Type | Req | Description |
|---|---|---|---|
| note | string | – | – |
| one_to_one | boolean | yes | True only when warnings is empty |
| source_language | string | yes | – |
| warnings | array | yes | Everything not carried over, with the manual page |
| zpl | string | yes | Converted ZPL, one ^XA...^XZ block per label |
No examples provided.
save_label Save label to account ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | Print density in dots per mm: 6, 8, 12 or 24 (8 = 203 dpi) |
| height_in | number | – | Label height in inches |
| name | string | – | Label name (default: 'Label from assistant') |
| width_in | number | – | Label width in inches |
| zpl | string | yes | Raw ZPL code |
No output schema declared.
No examples provided.
template_get Get label template ~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).
| Name | Type | Req | Description |
|---|---|---|---|
| template_id | string | yes | Template `id` from template_list (the id, not the display name) |
No output schema declared.
No examples provided.
template_list List label templates ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Filter by category |
| search | string | – | Substring match on id/tags |
No output schema declared.
No examples provided.
tspl_preview Render TSPL label ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| index | integer | – | Label index in the stream |
| tspl | string | yes | Raw TSPL/TSPL2 code |
No output schema declared.
No examples provided.
tspl_validate Validate TSPL ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| tspl | string | yes | Raw TSPL/TSPL2 code |
| Name | Type | Req | Description |
|---|---|---|---|
| diagnostics | array | yes | – |
| summary | object | yes | – |
No examples provided.
zpl_command_help 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.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | 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. |
No output schema declared.
No examples provided.
zpl_compatibility Check printer 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.
| Name | Type | Req | Description |
|---|---|---|---|
| model | string | yes | Printer model slug, manufacturer/model, e.g. zebra/zd421 |
| zpl | string | yes | Raw ZPL code |
No output schema declared.
No examples provided.
zpl_preview Render ZPL label ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | ZPL 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 Validate ZPL ~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.
| Name | Type | Req | Description |
|---|---|---|---|
| dpmm | integer | – | 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_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 | yes | ZPL source, non-empty (^XA...^XZ) |
| Name | Type | Req | Description |
|---|---|---|---|
| diagnostics | array | yes | – |
| fields | array | – | – |
| rfid | array | – | – |

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.
remote · api.labelixa.com
claude mcp add --transport http com-labelixa-zpl 'https://api.labelixa.com/mcp'
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.
