Claude Code

Claude Code 是 Anthropic 的命令行编码工具。本页介绍它的设置文件、MCP 服务器、常用命令和 shell 函数。

配置#

Claude Code 的配置分为设置文件、MCP 服务器和可选的 shell 函数。

设置#

设置文件位置：

macOS / Linux：~/.claude/settings.json
Windows：$HOME\.claude\settings.json

在设置文件里写入：

json

{  "attribution": {    "commit": "",    "pr": ""  },  "language": "chinese",  "skipDangerousModePermissionPrompt": true}

{  "attribution": {    "commit": "",    "pr": ""  },  "language": "chinese",  "skipDangerousModePermissionPrompt": true}

MCP 服务器#

在 ~/.claude.json 里加上：

json

{  "mcpServers": {    "codex": {      "command": "codex",      "args": ["mcp-server"]    },    "context7": {      "type": "stdio",      "command": "npx",      "args": ["-y", "@upstash/context7-mcp"]    },    "shadcn": {      "type": "stdio",      "command": "npx",      "args": ["shadcn@latest", "mcp"]    }  }}

{  "mcpServers": {    "codex": {      "command": "codex",      "args": ["mcp-server"]    },    "context7": {      "type": "stdio",      "command": "npx",      "args": ["-y", "@upstash/context7-mcp"]    },    "shadcn": {      "type": "stdio",      "command": "npx",      "args": ["shadcn@latest", "mcp"]    }  }}

Shell 函数#

用同名 shell 函数包装 claude，每次启动自动带上基础参数。把函数加到 ~/.zshrc 或 PowerShell 的 $PROFILE 里。以下两种写法任选其一。

每次新建对话#

每次都新开对话，只带上基础参数。

Zsh：

zsh

claude() {  local base_args="--allow-dangerously-skip-permissions --permission-mode plan"
  command claude ${=base_args} "$@"}

claude() {  local base_args="--allow-dangerously-skip-permissions --permission-mode plan"
  command claude ${=base_args} "$@"}

PowerShell：

powershell

function claude {    $baseArgs = @("--allow-dangerously-skip-permissions", "--permission-mode", "plan")    $claudePath = (Get-Command claude -CommandType Application).Source
    & $claudePath @baseArgs @args}

function claude {    $baseArgs = @("--allow-dangerously-skip-permissions", "--permission-mode", "plan")    $claudePath = (Get-Command claude -CommandType Application).Source
    & $claudePath @baseArgs @args}

自动续接上次对话#

先尝试继续上次对话，失败则新建对话。

Zsh：

zsh

claude() {  local base_args="--allow-dangerously-skip-permissions --permission-mode plan"
  command claude ${=base_args} -c "$@" 2>/dev/null || command claude ${=base_args} "$@"}

claude() {  local base_args="--allow-dangerously-skip-permissions --permission-mode plan"
  command claude ${=base_args} -c "$@" 2>/dev/null || command claude ${=base_args} "$@"}

PowerShell：

powershell

function claude {    $baseArgs = @("--allow-dangerously-skip-permissions", "--permission-mode", "plan")    $claudePath = (Get-Command claude -CommandType Application).Source
    & $claudePath @baseArgs -c @args 2>$null
    if ($LASTEXITCODE -ne 0) {        & $claudePath @baseArgs @args    }}

function claude {    $baseArgs = @("--allow-dangerously-skip-permissions", "--permission-mode", "plan")    $claudePath = (Get-Command claude -CommandType Application).Source
    & $claudePath @baseArgs -c @args 2>$null
    if ($LASTEXITCODE -ne 0) {        & $claudePath @baseArgs @args    }}
