Common questions
Is LayerOne (DocX + Sign) safe?
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: DOCX_API_KEY, SIGN_API_KEY
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed 5 months ago, and the latest version (1.0.0) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

LayerOne MCP — DocX + Sign
Serveur MCP (Model Context Protocol) qui expose les API DocX et Sign de LayerOne directement aux agents IA (Claude Desktop, ChatGPT, Cursor, Windsurf, etc.).
Une fois branché, votre assistant IA peut, en langage naturel :
- DocX — générer des documents (PDF / DOCX), des factures électroniques Factur-X (réforme 2026), déposer / mettre à jour / télécharger des modèles Word, gérer leur historique de versions, et consulter le quota d'usage.
- Sign — envoyer un PDF à la signature électronique eIDAS / PAdES, suivre son statut, vérifier l'identité du signataire par SMS (OTP), télécharger le document signé, récupérer le certificat de preuve et valider l'intégrité cryptographique de la signature.
Installation
Le serveur se lance via npx — aucune installation manuelle requise. Ajoutez le bloc ci-dessous à la configuration MCP de votre client, en renseignant vos deux clés API.
Claude Desktop
Fichier claude_desktop_config.json :
{"mcpServers": { "layerone": { "command": "npx", "args": ["-y", "layerone-mcp"], "env": { "DOCX_API_KEY": "votre_cle_docx", "SIGN_API_KEY": "votre_cle_sign" } } } }
Cursor
Fichier ~/.cursor/mcp.json (ou réglages MCP du projet) — même format :
{"mcpServers": { "layerone": { "command": "npx", "args": ["-y", "layerone-mcp"], "env": { "DOCX_API_KEY": "votre_cle_docx", "SIGN_API_KEY": "votre_cle_sign" } } } }
ChatGPT / autres clients compatibles MCP
La plupart des clients MCP acceptent la même structure (command = npx, args = ["-y", "layerone-mcp"], env = vos deux clés). Reportez-vous à la documentation MCP de votre client pour l'emplacement exact du fichier de configuration.
Obtenir les clés API
Créez un compte gratuit sur https://dev.layerone.fr, puis générez vos clés dans l'onglet « Clés API » :
- une clé DocX → variable d'environnement
DOCX_API_KEY; - une clé Sign → variable d'environnement
SIGN_API_KEY.
Le compte gratuit offre 20 documents DocX et 10 signatures Sign par mois.
Les clés ne sont jamais écrites en dur dans le code : elles sont lues uniquement
depuis les variables d'environnement passées par votre client MCP.

Fichiers : les modèles et PDF sont fournis aux outils encodés en base64
(
template_base64,pdf_base64). Pour les téléchargements, le serveur renvoie un
résumé (taille + aperçu base64 tronqué) plutôt que le binaire complet, afin de ne
pas saturer la conversation.
Développement local
cd integrations/mcpnpm install npm run build # compile src/ → dist/ DOCX_API_KEY=... SIGN_API_KEY=... node dist/index.js
Le serveur communique sur stdio (entrée/sortie standard) selon le protocole MCP.
Publication
- npm : publication automatique avec provenance via
.github/workflows/publish.yml(déclenché par une release GitHub). - MCP Registry : le manifeste
server.json(champnameio.github.GOLayerone/layerone, identique aumcpNamedepackage.json) permet la publication au registre officiel via l'outilmcp-publisher.
