Explaining AI Tools, MCP, and Skills for Developers
A DEV Community video follows a developer named Alice at Acme Corp to show how gaps across AI integration layers can cause multi-platform headaches and costly security flaws. It explains how AI tools let models produce structured intent and call functions. It describes the Model Context Protocol (MCP) as a standard that decouples tools from specific client implementations. The piece also covers how AI Skills supply business logic, judgment, and guardrails, along with risks such as prompt injection, tool poisoning, and missing human-in-the-loop controls. It further outlines implementing OAuth 2.1 authorization and scoping for secure remote MCP servers.
