Magic MCP → 21st MCP
Magic MCP is now the 21st MCP. The Magic MCP server (
@21st-dev/magic) has been replaced by the unified 21st MCP, installed via the 21st CLI — setup at 21st.dev/mcp. This package remains published as a thin compatibility proxy so old configs keep working.
Install the 21st MCP (recommended)
npx @21st-dev/cli@latest init --client cursor # or: claude | vscode | windsurf | codexOr add it manually — it is a plain HTTP MCP server:
{
"mcpServers": {
"21st": {
"url": "https://21st.dev/api/mcp",
"headers": { "x-api-key": "YOUR_21ST_API_KEY" }
}
}
}Get an API key at 21st.dev/mcp.
Old Magic API keys were reset. Keys issued by the old Magic console no longer work anywhere. Generate a fresh key at 21st.dev/mcp.
What this package does now (v0.2.0+)
npx -y @21st-dev/magic@latest API_KEY="..." still works: since v0.2.0 it is a small stdio proxy that forwards every MCP message to the 21st MCP server. Existing mcp.json entries that reference @21st-dev/magic keep functioning — but they now speak to the same server as the 21st CLI, with the tools available to the authenticated account.
