From f23b554a5b3e6bf90b2eb4a50d6e4ebe2f83ba63 Mon Sep 17 00:00:00 2001 From: Michal Date: Sat, 21 Feb 2026 04:00:35 +0000 Subject: [PATCH] feat: implement mcpctl install command with LLM-assisted auto-config Add install command for setting up MCP servers with: - Server lookup by name/package from registry search results - LLM-assisted README analysis for missing envTemplate (Ollama) - Interactive credential prompting with password masking - Non-interactive mode using env vars for CI/CD - Dry-run mode, custom profile names, project association - Zod validation of LLM responses, README sanitization - DI for full testability, 38 tests 128 tests passing total.
