Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 913 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name barcodegen.

  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 913 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 913 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    10 of 10 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-15T09:26:42.794011Z, within 180 days.

Capabilities

Tools 3

generate_barcode

Encode a value into any of 35 barcode and QR symbologies and return the rendered image. Supports QR Code, Data Matrix, PDF417, Aztec, EAN-13, UPC-A, Code 128/39/93, ITF-14 and more. Returns SVG markup by default (or a data: URI when asked), plus a link to the online generator pre-filled with the same value. Use "type" with the canonical name from list_barcode_types; common spellings like "qr" or "code-128" are accepted. Linear formats such as EAN-13 enforce strict charset and length rules and will fail on invalid input.

Discovered
get_barcode_type

Return the full technical reference for one symbology: character set, data length, check digit rules, X-dimension and quiet-zone guidance, print ratio, magnification, governing standard, inventor and year, typical applications, FAQ, and related formats. Use this to pick a format for a requirement, or to find out why generate_barcode rejected a value.

Discovered
list_barcode_types

List every symbology this server can generate (35 formats), grouped by family, with a one-line summary and sample data for each. Call this first when you are unsure which "type" to pass to generate_barcode. Optionally narrow by family (e.g. "EAN / UPC", "2D Barcodes") or category ("linear", "stacked", "2d").
