Code Tree

code-tree

[](https://www.npmjs.com/package/@febalist/code-tree) [](https://github.com/febalist/code-tree/actions/workflows/ci.yml)

A CLI tool and MCP server for quickly exploring project structure and codebase.

Requirements: Bun

Features

• 🌳 Directory structure scanning (like tree)
• 🔍 Code symbol extraction: classes, functions, interfaces, types
• 📝 Doc comment support
• 🚀 Accurate AST parsing via Tree-sitter (WASM)
• 🎯 10+ programming languages + Markdown
• ⚡ Automatic output optimization

Installation

# Global installation
bun add -g @febalist/code-tree

# Or use with bunx (no installation needed)
bunx @febalist/code-tree .

Usage

# Scan current directory
code-tree .

# Scan specific directory
code-tree src/

# Parse specific file
code-tree src/index.ts

# Multiple paths
code-tree src/ lib/

# With options
code-tree --depth 2 --no-symbols .
code-tree --ignore "*.test.ts" --ignore "*.spec.ts" src/

# Help
code-tree --help

Parameters

• Positional arguments: Paths to directories or files (default: .)
• --depth : Maximum traversal depth (default: 10)
• --symbols / --no-symbols: Include/exclude code symbols (default: auto)
• --comments / --no-comments: Include/exclude doc comments (default: auto)
• --ignore : Additional ignore patterns (repeatable)

Output Examples

Directory with symbols:

src/
├── index.ts
│     async run(args)
├── parser/
│   ├── index.ts
│   │     class ParserManager
│   │       async init()
│   │       private async loadLanguage(config: LanguageConfig): Promise
│   │       async parseFile(filePath: string): Promise
│   └── types.ts
│         type SymbolKind
│         interface CodeSymbol
│         interface FileSymbols

File with detailed breakdown:

src/parser/index.ts

  class ParserManager
    async init()
      locateFile()
    private async loadLanguage(config: LanguageConfig): Promise
    async parseFile(filePath: string): Promise

Supported Languages

• TypeScript (.ts, .tsx)
• JavaScript (.js, .jsx, .mjs, .cjs)
• Python (.py, .pyw)
• Go (.go)
• PHP (.php)
• Rust (.rs)
• Java (.java)
• C# (.cs)

• Markdown (.md, .mdx)

File Ignoring

Automatically ignored:

• .git, .svn, .hg, .DS_Store (always)
• node_modules, vendor, dist, build, __pycache__, venv, target, bin, obj, coverage
• Patterns from .gitignore
• Custom patterns via --ignore parameter

MCP Server

code-tree also provides an MCP (Model Context Protocol) server for integration with LLM clients like Claude Code.

The MCP server exposes the same capabilities and parameters as the CLI.

Integration Example

Add to Claude Code MCP configuration:

{
  "mcpServers": {
    "code-tree": {
      "command": "bunx",
      "args": ["@febalist/code-tree", "mcp"]
    }
  }
}
