They give access to more than 920 tools from every module. One account covers both routes.</div> </details> <details> <summary>Is there an OpenAPI document?</summary> <div>Yes. Every instance serves it at <code>/rest/v1/openapi.json</code> ein OpenAPI-3.1-Dokument, zugeschnitten auf den abfragenden Zugang: Es enthält nur die Operationen, die dieser tatsächlich ausführen darf. Es lässt sich direkt in n8n, Make, Postman oder einen Codegenerator importieren und für Werkzeuge mit Operationslimit nach Gruppen filtern. Dazu gibt es unter <code>/rest/v1/docs</code> eine lesbare Referenz im Browser — ohne Fremdskripte, direkt aus Ihrer Instanz.</div> </details> <details> <summary>REST or MCP — which should I take?</summary> <div>REST when a program, a script or an automation service is talking: plain HTTPS with JSON and an OpenAPI document to import or generate from. MCP when an AI system is talking: Claude, ChatGPT and the like understand by themselves what each tool does, because it carries its own description. Both lead to the same tools with the same permissions — you can switch at any time or use both in parallel.</div> </details> <details> <summary>Can I connect nordOFFICE to n8n, Make or Zapier?</summary> <div>Yes. The simplest way is the REST API: import the OpenAPI document or use an “HTTP Request” node with the header <code>Authorization: Bearer …</code> anlegen. Neuere n8n-Fassungen bringen zusätzlich einen eigenen MCP-Client-Knoten mit, dem Adresse und Token reichen. Für Export, Abgleich oder Benachrichtigungen ist damit kein Programmierauftrag nötig.</div> </details> <details> <summary>Does an account see more than the user does?</summary> <div>No. Every account runs with the permissions of exactly the user who created it and can be narrowed further — to “read only”, for instance. Whatever the user is not allowed to do, the interface cannot do either.</div> </details> <details> <summary>What does the interface cost?</summary> <div>Nothing — the module <strong>AI access (MCP)</strong> is free of charge. It is a core module of every nordOFFICE order; a superuser of your instance can switch it off at any time. There are no per-call fees either.</div> </details> <details> <summary>Does that apply to on-premise operation as well?</summary> <div>Yes.
