REAPER MCP Server

# Code Analysis Report - REAPER MCP Server ## Summary Analysis of the REAPER MCP Server codebase for: 1. Unused imports 2. Unused functions 3. Dead code paths 4. Duplicate function definitions ## Findings ### 1. Unused Imports ✅ **server/bridge.py** - All imports are used: - `os` - used in `os.environ.get()` and `os.path.expanduser()` - `json` - used for `json.dump()` and `json.load()` - `asyncio` - used for async operations and event loop - `logging` - used for logger - `Path` - used for path operations - `Optional`, `List`, `Dict`, `Any` - used in type hints ✅ **server/app.py** - All imports appear to be used: - All tool registration imports are called in `register_all_tools()` - Bridge imports are used ### 2. bridge_sync.py Usage ⚠️ **server/tools/bridge_sync.py** is actively used by several modules: - `bus_routing.py` - Heavy usage for synchronous bridge calls - `loop_management.py` - Uses ReaperBridge for sync calls - `tempo_time_management.py` - Uses ReaperBridge - `bounce_render.py` - Uses ReaperBridge - `groove_quantization.py` - Uses ReaperBridge - `advanced_midi_generation.py` - Appears in grep but needs verification This module provides a synchronous wrapper around the async bridge and IS needed for these tools. ### 3. Dead Code Paths ✅ No dead code patterns found: - No `if False:` blocks - No `if 0:` blocks - No `while False:` loops - No `while 0:` loops ### 4. Duplicate Function Definitions ✅ No duplicate function definitions found within the same scope: - `main()` appears in both `app.py` and `app_modern_simple.py` but these are different files - All other functions have unique names within their modules ### 5. Potential Issues Found #### Unused Files Based on the cleanup script and analysis: 🔍 **Potentially unused Python files:** - `server/app_modern_simple.py` - Alternative implementation, only referenced in test file - `server/app_modern_modular.py` - Another alternative implementation (mentioned in cleanup script) - `server/tools/track_basic.py` - Only imported by the unused `app_modern_modular.py` - Root level test files that should be in tests/: `test_bridge_functions.py`, `test_bridge_version.py`, `test_modern_pattern.py`, `test_quick.py`, `test_summary.py` 🔍 **Other unused files mentioned in cleanup script:** - `lua/mcp_bridge.lua` - Obsolete, replaced by `mcp_bridge_file_v2.lua` - Various backup files (`.bak`, `.old`, timestamped backups) - `generated_api/` directory - Replaced by modular tools/ structure #### Pattern Observations - The codebase follows a consistent pattern with registration functions - Each tool module exports a `register_*_tools()` function - The async/sync bridge pattern is intentional to support both paradigms - Multiple app implementations exist (`app.py`, `app_modern_simple.py`, `app_modern_modular.py`) but only `app.py` appears to be the active one ### Recommendations 1. **Keep bridge_sync.py** - It's actively used by 5+ modules for synchronous operations 2. **Remove unused app implementations**: - `server/app_modern_simple.py` - Not part of active codebase - `server/app_modern_modular.py` - Not part of active codebase - `server/tools/track_basic.py` - Only used by unused app_modern_modular.py 3. **Clean up root level test files** - Move or remove test files from root directory 4. **Run the cleanup script** - The `cleanup_unused_files.py` script already identifies most of these issues ### Clean Code Status ✅ **Core code is clean**: The main application files have: - No unused imports in active files (`bridge.py`, `app.py`, tool modules) - No dead code blocks (no `if False:` patterns) - No duplicate functions within same scope - Clear separation of concerns ⚠️ **Repository cleanup needed**: - Multiple alternative app implementations exist but aren't used - Test files scattered in root directory - Some backup/obsolete files remain ### Key Findings Summary 1. **bridge_sync.py is necessary** - Used by bus_routing, loop_management, tempo_time_management, bounce_render, and groove_quantization tools 2. **No dead code in active files** - All imports and functions in the main app flow are used 3. **Alternative implementations exist** - app_modern_simple.py and app_modern_modular.py appear to be experiments/alternatives that aren't part of the active codebase 4. **Cleanup script exists** - A `cleanup_unused_files.py` script already identifies most unused files The codebase architecture intentionally maintains both async (`bridge.py`) and sync (`bridge_sync.py`) interfaces to support different tool requirements, which is a valid design choice.
