TL;DR

Connect DATEV to Claude AI using MCP. Access accounting clients, documents, and payroll data with natural language. Step-by-step guide.

Connect DATEV to Claude

DATEV is the backbone of German accounting — used by nearly every tax consultant. With AnythingMCP, you can connect DATEV's Online APIs to Claude and manage accounting data with natural language.

What You Can Do

  • "List all my DATEV clients"
  • "Show documents uploaded this month for client Müller"
  • "Upload this receipt to DATEV Belege online"
  • "Which clients have pending documents?"

Setup

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
  1. Register at the DATEV Developer Portal and create an application
  2. Import the DATEV adapter in the store
  3. Enter your OAuth 2.0 credentials (Client ID, Client Secret, Auth URL, Token URL)
  4. Assign to an MCP server

Connect Claude

{
  "mcpServers": {
    "datev": { "url": "http://localhost:4000/mcp" }
  }
}

Why This Matters

DATEV has 15+ REST APIs but no MCP server. AnythingMCP bridges this gap, giving tax consultants and businesses AI-powered access to their DATEV data for the first time.
