21st.dev Rebuilds Unified CLI (@21st-dev/cli) and Transitions Magic MCP to Official 21st MCP

21st.dev deprecated legacy fragmented packages and consolidated all component discovery, generation, and publishing workflows into the new @21st-dev/cli and 21st MCP.

Verified State Diff

Comparison Mode:

- Previous State

Fragmented CLI tooling with separate @21st-dev/registry and @21st-dev/magic packages, requiring legacy Magic API keys.

+ Verified New State

Unified @21st-dev/cli with native 21st MCP server integration for Cursor, Claude Code, and Windsurf, and updated authentication tokens.

Impact & Verification Analysis

WHO IS AFFECTED

Frontend engineers, React developers, and users of AI coding IDEs (Cursor, Claude Code, Windsurf).

WHY IT MATTERS

Consolidates all AI agent tooling and component installation workflows into a single standardized CLI and protocol.

Full Fact Overview

21st.dev has unified its developer tooling into a cohesive ecosystem centered around the new @21st-dev/cli and the official 21st MCP server. Previously, developers had to install separate packages (@21st-dev/registry, @21st-dev/magic) and manage disparate API configurations. The transition streamlines all AI coding integrations across Cursor, Windsurf, Claude Code, and VS Code into a single npx command, while introducing updated authentication tokens at 21st.dev/mcp.
