Understanding APIs, Skills, and MCPs for AI Agents

Confused by APIs, Skills, and MCPs? Think of them like a professional kitchen. 1. APIs are the kitchen tools. Each one does a specific job. For example, Slack has APIs for sending messages and listing channels. Without tools, there's nothing for agents to work with. 2. Skills are the recipes. Text files loaded into the AI's context that tell it exactly what to do and how. "When the user asks to post in Slack, call chat.postMessage with the channel and message text." 3. MCPs are the full kitchen. They bundle the APIs, auth, and tool definitions so that the AI knows exactly what it can call and how. I believe that AI agents will soon interact with most products before humans do, so I wrote a new deep dive on how to use APIs, skills, and MCPs to make your product agent-ready. 📌 Subscribe to get it in your inbox tmr: https://creatoreconomy.so
