Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'mcp-builder' ] || [ -L ~/.agents/skills/'mcp-builder' ]; then echo 'A skill folder named mcp-builder already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/frankxai/agentic-creator-os' "$d" && git -C "$d" checkout --quiet '9dc9c9592ba6be55de0662b6c0b65ec01b08c775' -- '.claude/skills/mcp-builder' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/mcp-builder' ~/.agents/skills/'mcp-builder' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'mcp-builder' ~/.claude/skills/'mcp-builder' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
