I read the spec, it is fine, it is JSON-RPC with some sensible primitives, and on its own it would not have earned a post. I started caring about MCP the day it changed what an agent <em>is</em>. Before tool access, an agent generates text. You read the text, you decide, you act. After tool access, the agent acts. It opens the pull request, it queries the database, it restarts the container, it pages someone. The text was a suggestion. The tool call is an operation.</p>
