ORQENIO PRACTICAL GUIDE

Connecting ChatGPT and LLMs to business systems: APIs, MCP and permissions

Natural language can become a powerful interface for business software. Safe implementation requires clear separation of data access, tools and permissions.

The diagram summarizes the core of the guide. The details and decisions are explained below.
Reading is not writing

An assistant can initially search and summarize. Write access to CRM, email or tasks should be granted separately and deliberately.

APIs remain the foundation

Existing APIs and webhooks connect systems. MCP can add a standardized tool layer for AI on top.

Permissions per action

Reading a contact, creating an opportunity, sending an email or changing an invoice are very different risk classes and should have separate permissions.

Audit and approvals

Relevant actions should remain traceable. Where appropriate, AI prepares and a person confirms.
