Overview

MCP server for DATEV access from AI assistants and automation tools.

What is the Klardaten DATEV MCP server?

The Klardaten DATEV MCP server exposes DATEV data as MCP tools, so AI assistants and automation platforms can access it through a single, standardized interface. It uses the DATEVconnect Gateway and is currently read-only.

Capabilities

  • Query clients, postings, documents, invoices, and payroll data from the DATEV modules supported by the Gateway.
  • Use built-in prompts for common tasks.
  • Combine DATEV access with other tools your assistant already supports.
