SCORM Packager (HTML → SCORM 2004)

scorm-mcp-server

Turn self-contained HTML, a Claude Design .dc bundle or a mobile-learning platform content export (Excel activity templates + media) into a SCORM 2004 (or 1.2) package ready to import into any LMS — assets inlined for 100% offline, completion / progress / score tracking injected, ADL schemas bundled.

The bundled local harness (scorm-test-harness.html) playing a package: progress 0 → 100%, completion, and the live LMS API-call log (0 errors). Illustration.

An MCP server exposing three tools: scorm_package converts a finished HTML learning module into a .zip (PIF) any SCORM-compliant LMS can import, scorm_validate checks any existing SCORM zip (made by any tool) and explains exactly why an LMS would reject it, and scorm_selftest is a 1-second health check.

Principle: WRAP, don't rewrite. Your HTML is preserved; the tool only:

1. Inlines every asset (CSS, @import, fonts, JS, images, srcset, favicons) as data URIs → runs 100% offline.
2. Injects a small runtime that reports completion, progress (%) and time spent, with resume across sessions.
3. Generates the manifest and bundles the 15 official ADL XSD schemas — the manifest is validated against them (real conformance, not just "well-formed").

✅ Status — validated on a real LMS

• 325/325 automated checks green: 23 converter · 15 runtime · 15 MCP · 1 schema conformance (xmllint) · 6 security · 11 features · 13 auto-milestones · 21 V2 (bundle / .dc / score) · 10 output-dir · 9 tracking-signal · 32 hardening · 29 SCORM 1.2 · 12 CLI/batch · 16 web UI · 44 mobile-learning migration · 35 package validation · 33 question-level interactions — plus 6 bonus strict-runtime checks (scorm-again).
• SCORM Cloud (real LMS): imports cleanly (recognized as SCORM 2004 4th Ed., "manifest looks great"), and the dashboard reports completion = complete, success = passed, time tracked.

Input formats

Pass a .dc bundle as its folder or .zip (not the lone .dc.html, which is inert without its siblings).

Scores & quizzes (optional)

Set mastery_score (0..1) to enable score-based success and add sequencing objectives to the manifest. Report the score from your content in one line — no SCORM knowledge required:

window.SCORM2004.score(8, 0, 10);                                   // raw, min, max
window.dispatchEvent(new CustomEvent("scorm:score",    { detail: { raw: 8, min: 0, max: 10 } }));
window.dispatchEvent(new CustomEvent("scorm:progress", { detail: 0.5 }));  // 0..1
window.dispatchEvent(new CustomEvent("scorm:complete"));

The runtime maps these to cmi.score.*, sets success_status = passed/failed against mastery_score, and reports completion/progress. (dc:* event names are accepted as aliases.)

Question-level tracking (v2.3) — report each answer as a cmi.interactions record, so the LMS gradebook shows which questions were missed, not just the total:

window.SCORM2004.interaction({
  id: "quiz1-q3", type: "choice",
  description: "Which colour is the brand?",
  learnerResponse: "Blue", correctResponse: "Red",
  result: false, latencyMs: 12000,
});
// or, without touching the API:
window.dispatchEvent(new CustomEvent("scorm:interaction", { detail: { id: "q3", result: true } }));

Dialect-aware (2004 learner_response/timestamp vs 1.2 student_response/time, incorrect vs wrong) and best-effort by design: an LMS that refuses interaction writes gets a logged warning and the session carries on. Quizzes generated by the mobile-learning migration report their interactions automatically — one record per question, with the question text, the learner's answer, the expected answer and the latency.

SCORM 1.2, batch mode, CLI (v2.1)

SCORM 1.2 — pass scorm_version: "1.2" and you get a 1.2 manifest (validated against the bundled 1.2 XSDs, with adlcp:masteryscore when mastery_score is set). The injected runtime is adaptive: it speaks to whichever API the hosting LMS exposes (API_1484_11 or API), maps the data model (single lesson_status, 0-100 score, HH:MM:SS session time, 4096-char suspend data) and never downgrades a passed status.

Batch — batch: true treats input_path as a directory of courses (each sub-directory, .zip or .html = one course). One package per course, one consolidated batch-report.json, and a broken course never sinks the others.

CLI — no MCP client required:

npx -y scorm-mcp-server ui            # local drag & drop web UI
npx -y scorm-mcp-server pack course.html --title "My course"
npx -y scorm-mcp-server pack ./courses --batch --scorm-version 1.2
npx -y scorm-mcp-server validate pkg.zip   # conformance-check an existing package
npx -y scorm-mcp-server selftest      # 1-second health check

Web UI — ui opens a localhost page: drop an .html or .zip, pick the SCORM edition and an optional pass mark, download the package. Runs entirely on your machine; nothing is uploaded anywhere.

Library — buildPackage() is a public API for pipelines and SaaS backends:

import { buildPackage } from "scorm-mcp-server";
const r = await buildPackage({ html, title: "My course", scormVersion: "1.2", masteryScore: 0.6 });
// r.zip (Buffer) · r.fileName · r.warnings · r.milestoneIds …

Diagnostic — the scorm_selftest MCP tool packages a constant built-in HTML and reports version, duration and output path: it separates "server broken" from "input problem" in one second.

Validate any SCORM package (v2.3)

"Why does my LMS reject this zip?" — scorm_validate answers it for any SCORM package, not only those produced here, and the input is never modified:

npx -y scorm-mcp-server validate course.zip          # human-readable report
npx -y scorm-mcp-server validate course.zip --json   # machine-readable

Checks: zip readability, imsmanifest.xml at the ROOT (detects the classic "zipped the folder instead of its contents" mistake and says how to fix it), well-formed manifest, SCORM edition detection (2004/1.2), launchable organization/item/resource chain, launch file and every <file href> present in the archive (case-only mismatches flagged — they work on Windows and fail on Linux LMS servers), and full XSD validation against the official ADL schemas — using the package's own XSDs first and falling back to the embedded copies, so packages that ship without schemas validate too. Exit code 0/1 for CI pipelines; also exposed as the scorm_validate MCP tool and the validatePackage() library API.

Install

Option 0 — try it online, no install

https://scormpackager.vercel.app — drop a course, pick the SCORM edition, download the package. Files are processed in memory and never stored, but they do travel to a server; for real work use the local options below, where nothing leaves your machine (and there is no 4 MB limit).

Option A — one-click (recommended)

Download scorm-mcp-server-x.y.z.mcpb from the Releases, then in Claude Desktop → Settings → Extensions, drag-drop the .mcpb, pick an output folder, and enable it.

Option B — npm (any MCP client)

No install step: add this to your client's MCP config (~/Library/Application Support/Claude/claude_desktop_config.json for Claude Desktop):

{
  "mcpServers": {
    "scorm": {
      "command": "npx",
      "args": ["-y", "scorm-mcp-server"],
      "env": { "SCORM_OUTPUT_DIR": "/ABSOLUTE/PATH/scorm-packages" }
    }
  }
}

Registry name: io.github.giacomomaria81/scorm-mcp-server (MCP registry).

Option C — from source (developer)

git clone <this-repo> && cd scorm-mcp-server
npm install        # dist/ is prebuilt; npm run build is optional

Then point the config at node /ABSOLUTE/PATH/scorm-mcp-server/dist/index.js.

Restart Claude. The scorm_package tool is now available.
