Cline in Practice: Deploying an AI Coding Agent in Your IDE and Terminal

Cline is not just a code completion tool — it's a full AI coding Agent that runs in your IDE, terminal, or local Kanban board. It can read your entire codebase, execute shell commands, and open PRs autonomously — with your approval at every step.

Three Deployment Modes

Mode	Install	Best For
VS Code extension	VS Marketplace	Daily dev, inline diff review
JetBrains plugin	JetBrains Marketplace	IntelliJ/PyCharm users
CLI	`npm i -g cline`	CI/CD, scripted, headless
Kanban	`npm i -g kanban`	Multi-agent parallel, dependency chains

The same Cline Agent behaves consistently across all modes.

VS Code Extension

For daily development, with UI embedded in the editor.

Install:

Open VS Code → Extensions → search "Cline" → Install
Cline icon appears in the activity bar — click to open sidebar
Set API key (30+ providers supported)
Pick a model

Supported providers: OpenAI (GPT-4o / GPT-5 series), Anthropic Claude (Sonnet / Opus / Haiku), Google Gemini, DeepSeek, AWS Bedrock, OpenRouter, OpenAI-compatible (local Ollama / vLLM), MiniMax, Z.AI, Qwen, and more.

Automatic context: VS Code extension auto-collects open files, LSP diagnostics, terminal output, selected code, and git status — no manual config needed.

CLI Mode

npm i -g cline

cline                              # interactive
cline --yolo "Add JWT validation"  # one-shot
cline --yolo "Run tests"           # CI/CD

Kanban Multi-Agent

Kanban is Cline's killer feature — a local web app that runs multiple Agents in parallel, each in its own git worktree.

npx kanban

Workflow:

Create tasks — manually or ask the Agent in sidebar chat to decompose
Link tasks — ⌘+click card A to B; B auto-starts when A completes
Start — click play, Kanban creates an isolated worktree
Review — click card to see diff with checkpoint system
Commit or open PR — Agent handles merge conflicts
Clean up — move to trash (recoverable via resume ID)

MCP Integration

Mode	Config path
CLI	`~/.cline/mcp.json`
IDE extension	Cline panel → MCP Servers → Configure

{
  "mcpServers": {
    "filesystem": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path"] },
    "github": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-github"], "env": { "GITHUB_TOKEN": "<token>" } }
  }
}

Supports STDIO (local) and HTTP/SSE (remote, prefer Streamable HTTP).

Current Tool API

Cline runtime tools (SDK/CLI/Kanban, VS Code aligned):

Tool	Purpose
`bash`	Shell execution
`editor`	View/edit files
`read_files`	Batch read
`apply_patch`	Apply diffs
`search`	ripgrep search
`fetch_web`	HTTP + HTML→markdown
`ask_question`	Ask user

⚠️ Legacy XML tool names (read_file, replace_in_file, execute_command) are deprecated.

CI/CD Integration

cline --yolo "Run eslint, fix auto-fixable warnings"
cline --yolo "Analyze recent commits, update CHANGELOG.md"
cline --yolo "Review PR diff, flag potential security issues"

When to Use

Daily dev (completion, refactor, new features) ✅
Cross-file large refactoring ✅ (Kanban parallel)
CI/CD integration ✅ (CLI mode)
Pure UI/design work ❌

Summary

Cline's differentiation: multi-mode deployment (same Agent across IDE/CLI/Kanban), model-agnostic (30+ providers), human-in-the-loop (every step requires approval).
