What is the Klardaten MCP server for DATEV?
The Klardaten MCP server for DATEV 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.
