Features 13 powerful tools for everything from file comparison to repository backup and workspace analysis. ## Quick Start ```powershell git clone https://github.com/sandraschi/beyondcompare-mcp cd beyondcompare-mcp just ``` This opens an interactive dashboard showing all available commands. Run `just bootstrap` to install dependencies, then `just serve` or `just dev` to start. ### Manual Setup If you don't have `just` installed: ## Features - ** File and Folder Comparison**: Compare files and directories with Beyond Compare's powerful engine - ** Directory Synchronization**: Keep folders in sync with various sync modes (mirror, update, backup) - ** Diff Report Generation**: Generate detailed comparison reports in multiple formats - ** Multimedia Management**: Complete drive scanning, duplicate detection, and USB drive monitoring - ** Developer Workspace Tools**: Smart repository backup, health scanning, and workspace analysis - ** Intelligent Cleanup**: Automated artifact cleanup with node_modules filtering and space reclamation - ** Code Analysis**: Duplicate code detection and workspace snapshot comparison - ** Security First**: Comprehensive input validation and secure subprocess execution - ** MCP Compliant**: Built on the Model Context Protocol standards with 13 powerful tools - ** MCPB Packaging**: Easy deployment with MCPB packages for Claude Desktop (60.4 KB) - ** Cross-Platform**: Works on Windows, macOS, and Linux ## Security & Quality **Production Ready** - Comprehensive security audit passed **Input Validation** - Command injection and path traversal protection **Secure Dependencies** - Official MCP SDK 2.11+ with verified packages **Test Coverage** - 85%+ test coverage with security tests **Modern Architecture** - Python 3.10+ with type hints and async support ## Installation ### Prerequisites - [uv](https://docs.astral.sh/uv/) installed (RECOMMENDED) - Python 3.12+ ### Quick Start Run immediately via `uvx`: ```bash uvx beyondcompare-mcp ``` ### Claude Desktop Integration Add to your `claude_desktop_config.json`: ```json "mcpServers": { "beyondcompare-mcp": { "command": "uv", "args": ["--directory", "D:/Dev/repos/beyondcompare-mcp", "run", "beyondcompare-mcp"] } } ``` ### Prerequisites - **Python 3.10+** (required for MCP 2.11+) - **Beyond Compare 4+** installed on your system - **Claude Desktop** or compatible MCP client ### Quick Install (Recommended) **For Claude Desktop users:** 1. Download or build the latest `.mcpb` package. 2. Drag the `.mcpb` file to Claude Desktop or use Settings > MCP > Install Extension 3. Beyond Compare will be auto-detected (or configure path when prompted) ### Install from Source ```bash git clone https://github.com/sandraschi/beyondcompare-mcp.git cd beyondcompare-mcp pip install -e ".[dev]" ``` ## Configuration The MCP server auto-detects Beyond Compare installation (including Beyond Compare 5), but you can customize via environment variables: ```ini # Optional: Path to Beyond Compare executable (auto-detected if not specified) BEYOND_COMPARE_PATH="C:\\Program Files\\Beyond Compare 4\\BCompare.exe" # Optional: Log level (DEBUG, INFO, WARNING, ERROR, CRITICAL) LOG_LEVEL=INFO # Optional: Directory to store temporary script files BC_SCRIPTS_DIR="./bc_scripts" # Optional: Command timeout in seconds COMMAND_TIMEOUT=30 ``` ## Available Tools The MCP server provides **13 powerful tools** for file comparison, multimedia management, and developer workflows: ### **Core Comparison Tools** #### 1. `compare_files` Compare two files using Beyond Compare's engine ```json { "name": "compare_files", "arguments": { "left_path": "/path/to/file1.txt", "right_path": "/path/to/file2.txt", "output_report": "/path/to/report.html" } } ``` #### 2. `compare_folders` Compare two directories with optional subfolder inclusion ```json { "name": "compare_folders", "arguments": { "left_path": "/path/to/folder1", "right_path": "/path/to/folder2", "include_subfolders": true, "output_report": "/path/to/report.html" } } ``` #### 3. `sync_folders` Synchronize directories using Beyond Compare ```json { "name": "sync_folders", "arguments": { "source_path": "/path/to/source", "target_path": "/path/to/target", "sync_mode": "mirror", "dry_run": true } } ``` **Sync Modes:** - `mirror`: Make target identical to source - `update`: Copy newer files from source to target - `backup`: Copy only missing files to target ### **Multimedia & Drive Tools** #### 4. `multimedia_drive_scanner` Scan multimedia drives (E:, F:, K:, L:) for complete inventory with filtering options #### 5. `find_multimedia_duplicates` Find duplicate multimedia files across drives using content hashing #### 6. `detect_usb_drives` Detect and list all connected USB drives with detailed information ### **Developer Workspace Tools** #### 7. `backup_dev_repositories` Smart backup of development repositories with intelligent filtering - Excludes `node_modules`, `__pycache__`, build artifacts - Preserves Git essentials and project structure - Supports compression and incremental backups - for backing up `D:/dev/repos` with space optimization #### 8. `analyze_dev_workspace` Comprehensive analysis of development workspace - Language usage statistics and repository insights - Dependency analysis (package.json, requirements.txt, etc.) - Disk usage analysis and optimization opportunities - Generates detailed HTML reports #### 9. `scan_repo_health` Scan repository health and identify potential issues - Git status checks across all repositories - Large file detection and security issue identification - Outdated dependency scanning - Automated fix options for common issues #### 10. `cleanup_dev_artifacts` Clean up build artifacts and temporary files across repositories - Safely removes `node_modules`, `__pycache__`, `.next`, `dist/` folders - Configurable size thresholds and target patterns - Dry-run mode for safe preview - Significant disk space reclamation #### 11. `find_duplicate_code` Find duplicate code across repositories for refactoring opportunities - Cross-repository duplicate detection - Configurable similarity thresholds - Supports multiple file types (*.py, *.js, *.ts, etc.) - Detailed similarity reports #### 12. `compare_workspace_snapshots` Compare workspace snapshots to identify changes over time - Track repository additions, deletions, and modifications - Detailed change analysis with size differences - for monitoring workspace evolution #### 13. `selective_restore` Selectively restore specific projects or files from backup - Flexible pattern-based restoration - Structure preservation options - Conflict resolution and overwrite controls ## Development & Testing ```bash # Install development dependencies pip install -e ".[dev]" # Run tests with coverage pytest --cov=beyondcompare_mcp --cov-report=term-missing # Code formatting black src tests isort src tests # Type checking mypy src ``` ## Packaging & Distribution This repository is SOTA 2026 compliant and uses the officially validated `@anthropic-ai/mcpb` workflow for distribution. ### Pack Extension To generate a `.mcpb` distribution bundle with complete source code and automated build exclusions: ```bash # SOTA 2026 standard pack command mcpb pack . dist/beyondcompare-mcp.mcpb ``` ## Security Features -
