Everyone's debating MCP vs CLI.
Meanwhile MCP is already obsolete.
RAG was scaffolding to get information into the model. MCP is scaffolding to get actions out. The Bitter Lesson keeps teaching the same class: scaffolding dies.
Prompt engineering. Dead.
Retrieval pipelines. Dying.
MCP. Next.
Because AI adapts to us faster than we adapt to it.
Last month I onboarded our Head of GTM into our monorepo. Instructions: "install Claude."
Claude installed the GitHub CLI, walked her through auth, cloned the repo, opened a branch. No MCP. No custom tooling.
We keep building bridges to the model. The model is already on our side of the river.
So what actually matters? Not how agents discover tools. Who controls what they do.
A human executes dozens of actions per day. An agent executes thousands per hour. Least-privilege is now the only problem.
MCP is noise. The trust model is the signal.
