# corebapp > corebapp - the Enterprise Application Building System to build internal business applications with no code. corebapp works according to the “Lego principle.” Predefined building blocks (data models, views, integrations, RBAC, etc.) are used to create complex business apps without writing source code. This eliminates the security risks of AI-generated code and the high costs of traditional custom development. Since no code is generated, there is no need for traditional lifecycle management for outdated libraries or complex deployments. The corebapp platform is designed for enterprise scalability (SSO, for example, via ADFS, RBAC, API coupling via Points of Data (PODs)). As a European company, corebapp can also ensure full GDPR compliance, which is a decisive factor for European public sector and enterprise customers. ## MCP integration In addition to building internal applications using our UI, one can connect Anthropic Claude, OpenAI ChatGPT or other LLMs to our MCP server. This allows describing the problem or desired outcome, the LLM will transform this to a blueprint that can automatically be built on the corebapp platform. - [corebapp MCP](https://mcp.corebapp.com): More information on corebapp MCP integration
