# Magic MCP is a stdio MCP server providing UI component generation
# from 21st.dev. Toggled via lib/toggle-external.sh (same interface as
# gstack, emil-design-eng, etc.). Registered in Claude Code user scope.
#
# Default policy: DISABLED at install time. Rationale: MCP tools load
# into every Claude Code session and consume context tokens. Enable
# only when you're actively using Magic.
#
# API key: read from $REPO/.env (MAGIC_API_KEY=...) — NEVER committed.
# Template: $REPO/.env.example. Get a key at https://21st.dev/magic
