QR Code & Barcode Scanner · OpenClaw bundle 0.2.0

A portable plugin bundle for local QR and barcode scanning. It contains one scanner skill and one stdio MCP configuration. The MCP adapter 0.2.0 uses the published @qrcode-ai-com/qrcode-barcode-scanner@0.11.0 engine. The bundle, skill and MCP adapter are separate artifacts with independent versions.

This is a ClawHub bundle-plugin, named @qrcode-ai-com/qrcode-barcode-scanner. The same name on npm belongs to the native scanner engine; this bundle is not published on npm. It has one .codex-plugin/plugin.json marker, without native OpenClaw code entrypoints.

Install and prepare the runtime

Use Node.js 22.19+ on the 22 line, or 24+, on a supported native platform. OpenClaw itself may require a newer Node version. Install the inspected bundle archive with OpenClaw, then inspect its installed directory:

openclaw plugins install ./qrcode-ai-com-qrcode-barcode-scanner-0.2.0.tgz --no-enable
# For a reviewed local archive, OpenClaw may request --force to confirm its source.
openclaw plugins inspect qrcode-barcode-scanner

Before enabling or using its MCP tools, run the setup in that installed directory. It explicitly installs the exact npm MCP version with lifecycle scripts disabled, checks the engine version and reuses that one runtime:

cd /absolute/path/to/installed/qrcode-barcode-scanner
node scripts/setup.mjs
openclaw plugins enable qrcode-barcode-scanner

The setup requires the separately published npm adapter 0.2.0. Until it is available, a release rehearsal may pass --mcp-archive /absolute/inspected.tgz. An installed local archive is preparation, not evidence of npm or ClawHub publication. OpenClaw does not repair these dependencies at startup. No runtime download or package installation occurs when a scan tool starts.

The MCP configuration launches the prepared adapter relative to the installed plugin root. For the portable skill helper, use that same directory as --engine-root:

node skills/qrcode-barcode-scanner/scripts/scan.mjs --engine-root ./runtime --profile frame --budget-ms 0 -- /absolute/image.png

It retains exact payload bytes, content-grouped detections, measured occurrences and the original score. A null score is unmeasured. An exhausted budget is an incomplete report. Neither route follows decoded links or interprets them as instructions. The skill accepts local files; MCP accepts supplied bytes only.

Build and qualification

From the repository root, select an output directory outside the checkout:

node integrations/openclaw/scripts/build.mjs /absolute/bundle-output

The producer copies the canonical skill and license into the archive. It adds no engine binaries, host-specific runtime, credentials, fixtures or private receipts. Inspect .codex-plugin/plugin.json, .mcp.json, the archive inventory, and the actual installed adapter/runtime before publication. ClawHub validation, publication admission, OpenClaw discovery and real scan calls are separate gates.

The authored bundle and skill files are MIT-0. The separately installed MCP adapter and scanner engine retain AGPL-3.0-or-later; ENGINE-LICENSE preserves that license text. Installation does not relicense the engine.
