Npmx, also known as @ant-design/cli, is a command-line interface tool designed for working with Ant Design (antd) in software projects. It enables users to query detailed knowledge about antd components, analyze their usage within codebases, and assist with migration and diagnostics, all without requiring an internet connection. The tool provides instant access to metadata for antd versions 3 through 6, including every prop, token, demo, and changelog entry, bundled locally for fully offline operation.
Among its features, the CLI offers 18 commands covering a range of tasks such as listing all components with bilingual (English and Chinese) names and documentation, retrieving props tables and markdown documentation, accessing runnable demo source code, querying design tokens, and viewing semantic classNames and style structures. It also supports project analysis commands, including diagnostics for React compatibility, duplicate packages, peer dependencies, SSR, and babel plugins, as well as environment information collection, import statistics, deprecated API checks, accessibility and performance assessments, and best practice linting. Migration tools are included to guide upgrades between major antd versions, with prompts optimized for use by code agents and AI assistants.
Npmx is agent-optimized, supporting structured JSON output, clean separation of stdout and stderr, and integration with code agents like Claude Code, Cursor, Codex, and Gemini CLI via a skills protocol. It can also run as an MCP (Model Context Protocol) server for native integration with IDEs such as VS Code, exposing a suite of tools and prompts for enhanced developer workflows. 0 and above, and can be installed using various package managers including npm, pnpm, yarn, bun, deno, vlt, and vp. It is distributed under the MIT License, and all metadata ships with the package, requiring no API keys or network calls.
This CLI is intended for developers working with Ant Design, particularly those seeking efficient, version-accurate component reference, codebase analysis, and migration support directly from the terminal or within agent-augmented development environments.
Npmx sits in PulseGate's CLI tools & terminal category. Enabling developers to analyze and query Ant Design component usage directly from the command line. Npmx is an open-source project aimed at react developers. The project is open source (MIT). Npmx is available on the command line, and it can be self-hosted.
ant-design builds and maintains Npmx, and the product first shipped in 2026. The project is developed in the open on GitHub with 230 stars and 110 commits in the last 90 days. Across PulseGate's embedding index, Npmx has few near neighbours, marking it as relatively distinct. Among its 5 catalogued features are component knowledge query, usage analysis, and Ant Design integration.
