I built an MCP server on AWS Bedrock in 30 minutes. Here's the exact code.

MCP (Model Context Protocol) is the most important AI infrastructure pattern of 2026. Anthropic built it, the Linux Foundation now owns it, and AWS just made it a first-class citizen in Bedrock AgentCore. 97 million SDK downloads. 13,000+ servers built by the community. And as of this month, AWS is deploying them as managed services inside your existing cloud infrastructure. This is the tutorial I wish existed when I started. Not theory. Actual working code that deploys a real MCP server connected to AWS services in under 30 minutes. What MCP Actually Is (In One Paragraph) MCP is the protocol that lets AI agents use external tools reliably. Without it, your agent either hardcodes tool integrations (brittle, unmaintainable) or hallucinates function calls that don't exist. With MCP, you define tools once as a server. Any agent — Claude, Cursor, your own custom Bedrock agent — can discover and use those tools via a standardized interface. Think USB-C for AI tools. Build once, plug in anyw
