ctx7 CLI

The Context7 CLI does three things: fetches up-to-date library documentation, manages AI coding skills, and sets up Context7 MCP for your editor.

Make sure the CLI is up to date before running commands:

bash

npm install -g ctx7@latest

Or run directly without installing:

bash

npx ctx7@latest <command>

Context7 CLI主要实现三个功能：拉取最新的库文档、管理AI编程技能，以及为你的编辑器配置Context7 MCP。

运行命令前请确保CLI已更新至最新版本：

bash

npm install -g ctx7@latest

或者无需安装直接运行：

bash

npx ctx7@latest <command>

Authentication

身份验证

bash

ctx7 login               # Opens browser for OAuth
ctx7 login --no-browser  # Prints URL instead of opening browser
ctx7 logout              # Clear stored tokens
ctx7 whoami              # Show current login status (name + email)

Most commands work without login. Exceptions:

skills generate

always requires it;

ctx7 setup

requires it unless

--api-key

or

--oauth

is passed. Login also unlocks higher rate limits on docs commands.

Set an API key via environment variable to skip interactive login entirely:

bash

export CONTEXT7_API_KEY=your_key

bash

ctx7 login               # Opens browser for OAuth
ctx7 login --no-browser  # Prints URL instead of opening browser
ctx7 logout              # Clear stored tokens
ctx7 whoami              # Show current login status (name + email)

大部分命令无需登录即可使用。例外情况：

skills generate

始终需要登录；

ctx7 setup

需要登录，除非传入了

--api-key

或

--oauth

参数。登录还可以解锁文档类命令的更高请求频率限制。

你可以通过环境变量设置API密钥，完全跳过交互式登录：

bash

export CONTEXT7_API_KEY=your_key

Common Mistakes

常见错误

Library IDs require a
```
/
```
prefix —
```
/facebook/react
```
not
```
facebook/react
```
Always run
```
ctx7 library
```
first —
```
ctx7 docs react "hooks"
```
will fail without a valid ID

Repository format for skills is

/owner/repo

— e.g.,

ctx7 skills install /anthropics/skills

```
skills generate
```
requires login — run
```
ctx7 login
```
first

库ID需要带有
```
/
```
前缀 — 应为
```
/facebook/react
```
而非
```
facebook/react
```
请始终先运行
```
ctx7 library
```
命令 — 没有有效ID的情况下运行
```
ctx7 docs react "hooks"
```
会失败

技能的仓库格式为

/owner/repo

— 例如：

ctx7 skills install /anthropics/skills

```
skills generate
```
需要登录 — 请先运行
```
ctx7 login
```
