TL;DR: Magic MCP was renamed and unified into the 21st MCP. Same product, new home.
- New setup (recommended):
npx @21st-dev/cli@latest init --client <cursor|claude|vscode|windsurf|codex>, or add the HTTP server https://21st.dev/api/mcp with an x-api-key header.
- Existing configs keep working:
npx -y @21st-dev/magic@latest API_KEY="..." still runs - since v0.2.0 this package is a thin proxy to the 21st MCP.
- Old API keys were reset. Keys from the retired Magic console no longer work anywhere. Get a fresh key at https://21st.dev/mcp.
- Old tool names still work:
21st_magic_component_builder → generate, 21st_magic_component_inspiration → get_inspiration, 21st_magic_component_refiner → generate, logo_search → search_logo. The server translates them automatically; prefer the new names.
- The current server has a much larger toolset (catalog search, code retrieval, themes, templates, teams, UI generation with variants) - connect and call
tools/list.
All pre-0.2.0 issues were closed as they targeted the retired standalone server. If something misbehaves on 0.2.0+, open a new issue.
