Worth adding to the list: TUIs have found an unexpected new job as the "read" layer for AI agents — they already render exactly the state the agent needs (fleet health, live metrics, log tails) without a separate REST API, and the MCP server just maps that state to tool calls. The shared human/agent view is what makes it interesting. That's the direction we took with Servonaut, a server management TUI with a built-in MCP server: https://github.com/zb-ss/servonaut.
