Building with AI in 2026: A Long Guide That Ties Funnels, Boring Automation and MCP into One Agency

Six videos ask the same question from different angles: can you really make money with AI? One spends $250k a month on ads to build funnels, one shows boring automations that earn $1,200 a day, one gives every tool to Claude via MCP on n8n, one audits the myth of 10 tiny shops, one maps a $10k-a-month outreach agency from scratch, and one lists five beginner-friendly ideas. This guide ties them into one runnable workflow, in plain language and step by step.
