scorm-mcp-server
Turn self-contained HTML, a Claude Design .dc bundle or a Teach on Mars content export 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 a single tool, scorm_package, that converts a finished HTML learning module into a .zip (PIF) any SCORM-compliant LMS can import.
Principle: WRAP, don't rewrite. Your HTML is preserved; the tool only:
- Inlines every asset (CSS,
@import, fonts, JS, images, srcset, favicons) as data URIs → runs 100% offline.
- Injects a small runtime that reports completion, progress (%) and time spent, with resume across sessions.
- Generates the manifest and bundles the 15 official ADL XSD schemas — the manifest is validated against them (real conformance, not just "well-formed").
🇫🇷 README in English for reach; the in-depth handoff doc (PASSATION.md) and guides are in French.
✅ Status — validated on a real LMS
- 256/256 automated checks green: 23 converter · 15 runtime · 14 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 Teach on Mars migration — 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
A single self-contained .html (e.g. Claude Design "standalone HTML" export) | assets inlined, runtime injected — v1 path |
A folder or .zip (multi-file module) | whole tree preserved; entry HTML inlined; manifest lists every file |
A Claude Design .dc bundle (*.dc.html + support.js + _ds/) | auto-detected; CDN libs (React/Babel…) vendored offline via window.__resources (no source patch); runtime injected before support.js |
A Teach on Mars content export (Excel activity templates + media/) | auto-detected; an interactive HTML course is rebuilt from the templates — Mobile Course cards (info / transition / flash), Quiz Game questions, media codes ([media:…], [H1:…], [quote:…], !!), scored quizzes reporting cmi.score — then packaged. Course title derived from the template names; with --batch, a whole catalogue migrates in one run |
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);
window.dispatchEvent(new CustomEvent("scorm:score", { detail: { raw: 8, min: 0, max: 10 } }));
window.dispatchEvent(new CustomEvent("scorm:progress", { detail: 0.5 }));
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.)
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
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 selftest
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 });
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.
Install
Option 0 — try it online, no install
https://scorm-packager-peach.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
Then point the config at node /ABSOLUTE/PATH/scorm-mcp-server/dist/index.js.
Restart Claude. The scorm_package tool is now available.
Usage
In a conversation: build your module with Claude Design, then say "package this module as SCORM." Claude calls scorm_package and returns the path to the .zip.
Progress & completion — it just works
You don't have to prepare anything: if your HTML declares no milestone, the packager auto-generates them from the document structure (sections → articles → headings, capped at 8, trigger view). Plain HTML gets meaningful progress out of the box. Disable with auto_milestones: false. Want success_status = passed on completion without touching the HTML? Pass success_on_completion: true.
Declarative milestones (recommended for fine control)
Mark the meaningful steps directly in your HTML — explicit milestones always take precedence over auto-generation. The runtime computes progress_measure = milestones_reached / total, and sets completion_status = "completed" once all are reached.
data-jalon="unique-id" | declares a milestone |
data-trigger="view" | reached when scrolled into view (default) |
data-trigger="click" | reached on click |
data-trigger="ended" | reached when a video/audio ends |
<section data-jalon="intro" data-trigger="view">…</section>
<button data-jalon="read-pitch" data-trigger="click">I read it</button>
<video data-jalon="demo" data-trigger="ended">…</video>
Recommended: 4–8 milestones per micro-module. Resume is automatic (cmi.suspend_data + cmi.location); progress never regresses.
Programmatic milestones — window.SCORM2004.reach("quiz-passed") works even if the id has no data-jalon element: unknown ids are declared on the fly and count in the total. To register one before it's reached (accurate denominator), use window.SCORM2004.declare("quiz-passed") early. Both survive resume.
Success status (opt-in) — add data-scorm-success="on-completion" on any element (e.g. <body>) and the runtime also sets cmi.success_status="passed" when the module completes. Without it, success_status is never written.
Language — the tool's language (BCP-47, default fr-FR) is applied as <html lang="…"> when the source HTML doesn't declare one.
Security — asset references are confined to the module folder: ../ or absolute paths outside it are never inlined (a warning is emitted instead).
Test it without an LMS account
Open scorm-test-harness.html via a tiny local server and drop a generated .zip into it:
python3 -m http.server 8000
You'll see live progress %, completion, and the full log of LMS API calls (0 errors expected).

npm install
npm run build
