MCP (Model Context Protocol) promises standardized tool discovery for AI agents, but it comes with a hidden cost: every tool definition, name, description, and parameter schema gets loaded into your context window on every single turn. Connect to a bloated MCP server with 40 or 50 tools and you've burned tens of thousands of tokens before asking a single question. This video puts MCP to the test against a compelling alternative — using CLIs as the communication channel between your agent and remote servers.
Through live demos with Claude Code and a Kubernetes cluster, the video walks through both approaches side by side: querying cluster health and component relationships through an MCP server, then accomplishing the same task using the `dot-ai` CLI with a handful of lightweight skill files. The core insight is that LLMs are already trained on widely-used CLIs like `kubectl`, `gh`, and `aws`, making them zero-cost to use. For custom or internal tools, small skill files can teach the LLM what it needs to know at a fraction of the context cost of MCP schemas. The verdict isn't that one approach always wins — well-designed MCP servers with a small number of high-level tools remain a strong choice for centralized, cross-agent deployments — but when context efficiency matters or you're working with tools the LLM already knows, CLIs are often the smarter path.
