This project provides a versatile code scanning tool built with TypeScript and Node.js. It leverages the Tree-sitter parsing library to analyze source code and extract structural information. It can operate both as a command-line interface (CLI) tool and as an MCP (Model Context Protocol) server. > **Note:** This tool is under active development. While core functionality is operational, some features or specific language parsers may not be fully tested and might contain bugs or limitations. ## Features * **Code Definition Extraction:** Identifies functions, classes, variables, interfaces, methods, etc. * **Multi-Language Support:** Parses JavaScript (`.js`, `.jsx`), TypeScript (`.ts`, `.tsx`), C# (`.cs`), PHP (`.php`), CSS (`.css`), and Python (`.py`) via Tree-sitter. * **.gitignore Aware:** Automatically respects rules defined in `.gitignore` files. * **Flexible Filtering:** Filter results by definition type, modifiers (`public`, `private`), name patterns (regex), and file path patterns. * **Multiple Output Formats:** Generates results in Markdown (default), XML, or JSON. * **Configurable Detail Levels:** Output verbosity: `minimal`, `standard` (default), `detailed`. * **Dual Mode Operation:** Run as a standalone CLI tool or as an integrated MCP server. ## Usage Modes ### 1. Command-Line Interface (CLI) Run the scanner directly from your terminal. This mode requires the `--directory` argument specifying the target codebase. **Basic Usage:** ```bash node build/index.js --directory /path/to/your/codebase ``` **Common Options:** * `-d, --directory <path>`: (Required) Absolute or relative path to the directory to scan. * `-p, --patterns <patterns...>`: Glob patterns for file extensions (e.g., `"**/*.ts"` ` "**/*.js"`). Defaults to JS, TSX, CS, PHP, CSS, PY files. * `-f, --format <format>`: Output format (`xml`, `markdown`, `json`). Default: `markdown`. * `-l, --detail <level>`: Level of detail (`minimal`, `standard`, `detailed`). Default: `standard`. * `--include-types <types...>`: Only include specific definition types (e.g., `class`, `method`). * `--exclude-types <types...>`: Exclude specific definition types. * `--include-modifiers <modifiers...>`: Only include definitions with specific modifiers (e.g., `public`). * `--exclude-modifiers <modifiers...>`: Exclude definitions with specific modifiers. * `--name-pattern <regex>`: Include definitions matching a JavaScript regex pattern. * `--exclude-name-pattern <regex>`: Exclude definitions matching a JavaScript regex pattern. * `--include-paths <paths...>`: Additional file path patterns (glob) to include. * `--exclude-paths <paths...>`: File path patterns (glob) to exclude. * `-h, --help`: Display detailed help information for all options. **Example (Scan TypeScript files in `src`, output detailed JSON):** ```bash node build/index.js -d ./src -p "**/*.ts" -f json -l detailed ``` ### 2. MCP Server Mode (`scan_code` tool) If run without the `--directory` argument, the tool starts as an MCP server, listening for requests via standard input/output. This allows integration with MCP clients like AI assistants. * **Tool Name:** `scan_code` * **Description:** Scans a specified directory for code files and returns a list of definitions according to the provided filters. * **Input Schema:** Accepts arguments corresponding to the CLI options. The `directory` property is required. ```json { "type": "object", "properties": { "directory": { "type": "string", "description": "Absolute path to the directory to scan." }, "filePatterns": { "type": "array", "items": { "type": "string" }, "description": "Glob patterns for files.", "default": ["**/*.js", ..., "**/*.py"] }, "outputFormat": { "type": "string", "enum": ["xml", "markdown", "json"], "default": "markdown" }, "detailLevel": { "type": "string", "enum": ["minimal", "standard", "detailed"], "default": "standard" }, "includeTypes": { "type": "array", "items": { "type": "string" } }, "excludeTypes": { "type": "array", "items": { "type": "string" } }, "includeModifiers": { "type": "array", "items": { "type": "string" } }, "excludeModifiers": { "type": "array", "items": { "type": "string" } }, "namePattern": { "type": "string", "description": "Regex pattern for names." }, "excludeNamePattern": { "type": "string", "description": "Regex pattern to exclude names." }, "includePaths": { "type": "array", "items": { "type": "string" } }, "excludePaths": { "type": "array", "items": { "type": "string" } } }, "required": ["directory"] } ``` * **Example Usage with AI Assistant:** "Use code-scanner-server scan_code on directory /path/to/project outputting xml format." ## Installation 1. **Prerequisites:** Ensure you have Node.js and npm installed. 2. **Clone (Optional):** If you don't have the code, clone the repository. ```bash # git clone <repository_url> # cd code-scanner-server ``` 3. **Install Dependencies:** ```bash npm install ``` 4. **Build:** Compile the TypeScript code. ```bash npm run build ``` This creates the executable JavaScript file at `build/index.js`. ## Configuration (MCP Server) To use the MCP server mode, add it to your MCP client's configuration file (e.g., `claude_desktop_config.json` for the desktop app or `cline_mcp_settings.json` for the VS Code extension). **Important:** Replace `/path/to/code-scanner-server` in the example below with the **absolute path** to this project's directory on your system. **Example (`claude_desktop_config.json` / `cline_mcp_settings.json`):** ```json { "mcpServers": { "code-scanner-server": { "command": "node", "args": [ "/absolute/path/to/your/code-scanner-server/build/index.js" // <-- Replace this path! (e.g., "C:\\Users\\YourUser\\Projects\\code-scanner-server\\build\\index.js" on Windows) ], "env": {}, "disabled": false, "autoApprove": [] // Add tool names here for auto-approval if desired } } } ``` *Remember to restart your MCP client application (IDE, Desktop App) after modifying the configuration for changes to take effect.* ## Development * **Watch Mode:** Automatically rebuild the project when source files change: ```bash npm run watch ``` * **Debugging (MCP Mode):** Debugging MCP servers over stdio can be complex. Use the MCP Inspector tool for easier debugging: ```bash npm run inspector ``` This starts the server with the Node.js inspector attached and provides a URL to connect debugging tools (like Chrome DevTools). ## Acknowledgments This project was significantly developed with the assistance of AI, primarily using Google's Gemini 2.5 Pro model accessed via the Roo Code extension for Visual Studio Code. ## License This project is licensed under the GNU General Public License v3.0 - see the [LICENSE](LICENSE) file for details.
