Your CrewAI agent has the same problem web servers had in 2005: it accepts user input without sanitizing. Prompt Injection is the #1 vulnerability in the OWASP GenAI Top 10 of 2026, and attacks are no longer theoretical: in May 2026, a compromised agent exfiltrated a complete PostgreSQL database in under 2 minutes.
Your AI model hallucinates with your company’s data. Is the fix RAG, fine-tuning, or a better prompt? The right answer depends on a single question almost nobody asks. After implementing all four techniques in production, I’ve distilled the decision tree I wish I’d had when I started.
Today, every LLM has its own way of connecting to your databases and tools. It’s a chaos of proprietary integrations. MCP (Model Context Protocol) promises to end this by becoming the ‘universal plug’ of AI. We analyze if it’s truly the future or just another standard that will die trying.
