Source Tree Generator MCP server

This MCP Source Tree Server generates a file tree for a specified directory, following .gitignore patterns and excluding hidden directories. When integrated with Claude, it helps quickly visualize project structures and identify files that need editing.

Installation

Prerequisites

• Python 3.10 or higher
• uv package manager

Setup Instructions

First, install the uv package manager:

curl -LsSf https://astral.sh/uv/install.sh | sh

Next, navigate to the project directory and install dependencies:

cd /path/to/mcp-src-tree
uv sync

Configuration

Setting up in Claude for Desktop

Add the following configuration to your claude_desktop_config.json file:

{
    "mcpServers": {
        "src-tree": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/mcp-src-tree",  # Replace with the absolute path to the project directory
                "run",
                "tree.py"
            ]
        }
    }
}

Usage

Basic Usage

When using Claude, specify the root directory (one level above the src directory). For example:

/Users/username/GitHub/project/ のソースツリーを確認してください

Claude will respond with a visualization of your project structure:

はい、ソースツリーを確認させていただきます。
プロジェクトの構造を確認しました。以下のような構成になっています：
src/
└── xxxx/
    ├── __init__.py
    ├── converter.py
    ├── html_converter.py
    ├── image_processor.py
    ├── toc_analyzer.py
    └── utils.py

File Exclusion

The server automatically excludes certain files and directories:

• Directories starting with . (hidden directories)
• Files and directories matching patterns in the .gitignore file

For example, with the following .gitignore file:

__pycache__/
node_modules/
*.log

All __pycache__ directories, node_modules directories, and files with the .log extension will be excluded from the generated tree.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "src-tree" '{"command":"uv","args":["--directory","/path/to/mcp-src-tree","run","tree.py"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "src-tree": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/mcp-src-tree",
                "run",
                "tree.py"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "src-tree": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/mcp-src-tree",
                "run",
                "tree.py"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
