This server is designed to work alongsidepublic360-mcp-server, which provides AI access to Public 360° document and case management systems used by Nordic public sector organizations.

Company is in good standing.

This turns two separate data sources into a connected workflow where the AI can verify external data and update internal systems in one conversation.
