MCP Is Dead; Long Live MCP

a day ago

The industry discourse has shifted from MCP (Model Context Protocol) to CLIs (Command Line Interfaces) as the current trend, influenced by social media and industry hype cycles.
Token savings with CLIs exist, especially for well-known tools in the LLM's training dataset, but custom CLI tools require additional context and instructions, similar to MCP.
MCP over HTTP (as opposed to stdio) offers significant advantages for enterprise use, including centralized capabilities, better auth and security, telemetry, and dynamic content delivery.
Centralized MCP servers enable richer capabilities, easier management of stateful workloads in ephemeral environments, and improved observability and telemetry for organizational tool use.
MCP resources and prompts allow for dynamic, server-delivered content that is always up-to-date, facilitating org-wide knowledge sharing and consistent updates without manual syncs.
The article critiques the influencer-driven hype cycle in AI, comparing it to past trends like Ivermectin or anti-vax conspiracies, and emphasizes the need for engineering discipline in agentic engineering.
For organizations moving beyond individual 'vibe-coding' to structured agentic engineering, MCP provides the necessary architecture for consistency, quality, and correctness in AI-produced software.
