DATEVconnect Gateway

What is the DATEVconnect Gateway?
DATEVconnect is the official interface for securely connecting to DATEV desktop applications. With our DATEVconnect Gateway, you bring this technology to the cloud – without additional infrastructure.
DATEV Documentation for Desktop APIsFull Support
Direct connection to DATEV, compatible with PARTNERasp, DATEVasp & DATEVnet.
Minimal Installation
Easy setup by IT partners or DATEV, no maintenance required.
100% Data Protection
No data storage – all transmissions are GDPR-compliant.
MCP Server add-on
Connect DATEV data to any MCP client
The Klardaten MCP Server add-on lets you connect the Gateway with any MCP-compatible client, for example Langdock, Claude, or ChatGPT. Use it from AI assistants and automation tools without building a custom Gateway integration first.
The MCP Server is currently read-only. The DATEVconnect Gateway underneath supports both read and write access for direct API integrations.

What Customers Say
We’ve been using Klardaten's DATEVconnect Gateway for 16 months and couldn’t be happier with the impact on our business. The interface is incredibly stable, downtime is non-existent, and the admin effort for managing DATEV connections has dropped sharply. On top of that, their support is outstanding. The Klardaten team is professional and always willing to step in, even helping our customers directly with complex setups when our internal team needed backup.
With Klardaten, we found a powerful and straightforward way to connect customer systems to our time tracking application. The continuous development and lightning-fast support make the Klardaten team the only option for us.
I really appreciate the communication with your team. It feels like we are all pulling in the same direction, and we can rely on proactive responses whenever errors occur within the interface.
