What is the MCP tool index?
The MCP tool index is the continuously maintained German-language overview of all content on MCP servers and the MCP specification. The aim: anyone who wants to know how a specific tool — DATEV, Lexoffice, SAP, Personio, HubSpot, awork, sevdesk, weclapp, bexio, Microsoft 365, Notion, Slack, monday, Salesforce, Dynamics 365, SAP SuccessFactors, Shopware or an ERP system — can be connected to AI agents via MCP finds the matching in-depth advice here on one page.
Background: MCP is becoming the new connection standard between AI models and company systems. Anthropic introduced it in 2024, and Google, OpenAI and Microsoft have adopted it. Anyone who wants to use AI agents seriously in mid-sized companies today cannot avoid MCP.
The index covers 37 systems in the categories accounting, ERP, CRM, HR, project management, e-commerce, office and development, plus foundational guides and the central service page of our MCP integration agency.
Methodology: The index is based on our ongoing integration work and is maintained when systems change their APIs or new MCP implementations become relevant. Each entry links to its own practical guide with use cases, architecture and GDPR assessment.
