# The Agentic Company > Guides, tools, and reviews for companies becoming AI-first: agentic workflows, automation, product comparisons, and the explainers that make them work. ## Key Technical Documents ### Security & Governance - [Permission-Aware RAG for Enterprise Knowledge Systems](https://agntc.work/blog/permission-aware-rag.md): Permission-aware RAG applies role-based access control filters during retrieval, so sensitive chunks never reach an unprivileged context window. The control belongs at the vector store, not in the prompt. ### Agent Protocols & Interoperability - [MCP Server Architecture for Enterprise Tool Integration](https://agntc.work/blog/mcp-server-architecture.md): An enterprise MCP server is a typed, permissioned boundary between agents and internal systems. Design it around explicit tools, scoped credentials, and deterministic error contracts. ## Optional Resources - [JSON Article Index](https://agntc.work/api/index.json): Machine-readable index of all published articles. - [Full Text Archive](https://agntc.work/llms-full.txt): Aggregated raw text bundle of all documentation. - [RSS Feed](https://agntc.work/rss.xml): Full-text feed of all articles.
