```markdown
  1 | # Linux Compatibility Audit Report
  2 | **Date:** 2025-10-25
  3 | **Target Platform:** Ubuntu 24.04 LTS (primary), Fedora, Arch (secondary)
  4 | **Current Status:** Windows-optimized, partial Linux support
  5 | 
  6 | ---
  7 | 
  8 | ## Executive Summary
  9 | 
 10 | The KiCAD MCP Server was originally developed for Windows and has several compatibility issues preventing smooth operation on Linux. This audit identifies all platform-specific issues and provides remediation priorities.
 11 | 
 12 | **Overall Status:** 🟡 **PARTIAL COMPATIBILITY**
 13 | - ✅ TypeScript server: Good cross-platform support
 14 | - 🟡 Python interface: Mixed (some hardcoded paths)
 15 | - ❌ Configuration: Windows-specific examples
 16 | - ❌ Documentation: Windows-only instructions
 17 | 
 18 | ---
 19 | 
 20 | ## Critical Issues (P0 - Must Fix)
 21 | 
 22 | ### 1. Hardcoded Windows Paths in Config Examples
 23 | **File:** `config/claude-desktop-config.json`
 24 | ```json
 25 | "cwd": "c:/repo/KiCAD-MCP",
 26 | "PYTHONPATH": "C:/Program Files/KiCad/9.0/lib/python3/dist-packages"
 27 | ```
 28 | 
 29 | **Impact:** Config file won't work on Linux without manual editing
 30 | **Fix:** Create platform-specific config templates
 31 | **Priority:** P0
 32 | 
 33 | ---
 34 | 
 35 | ### 2. Library Search Paths (Mixed Approach)
 36 | **File:** `python/commands/library_schematic.py:16`
 37 | ```python
 38 | search_paths = [
 39 |     "C:/Program Files/KiCad/*/share/kicad/symbols/*.kicad_sym",  # Windows
 40 |     "/usr/share/kicad/symbols/*.kicad_sym",                      # Linux
 41 |     "/Applications/KiCad/KiCad.app/Contents/SharedSupport/symbols/*.kicad_sym",  # macOS
 42 | ]
 43 | ```
 44 | 
 45 | **Impact:** Works but inefficient (checks all platforms)
 46 | **Fix:** Auto-detect platform and use appropriate paths
 47 | **Priority:** P0
 48 | 
 49 | ---
 50 | 
 51 | ### 3. Python Path Detection
 52 | **File:** `python/kicad_interface.py:38-45`
 53 | ```python
 54 | kicad_paths = [
 55 |     os.path.join(os.path.dirname(sys.executable), 'Lib', 'site-packages'),
 56 |     os.path.dirname(sys.executable)
 57 | ]
 58 | ```
 59 | 
 60 | **Impact:** Paths use Windows convention ('Lib' is 'lib' on Linux)
 61 | **Fix:** Platform-specific path detection
 62 | **Priority:** P0
 63 | 
 64 | ---
 65 | 
 66 | ## High Priority Issues (P1)
 67 | 
 68 | ### 4. Documentation is Windows-Only
 69 | **Files:** `README.md`, installation instructions
 70 | 
 71 | **Issues:**
 72 | - Installation paths reference `C:\Program Files`
 73 | - VSCode settings path is Windows format
 74 | - No Linux-specific troubleshooting
 75 | 
 76 | **Fix:** Add Linux installation section
 77 | **Priority:** P1
 78 | 
 79 | ---
 80 | 
 81 | ### 5. Missing Python Dependencies Documentation
 82 | **File:** None (no requirements.txt)
 83 | 
 84 | **Impact:** Users don't know what Python packages to install
 85 | **Fix:** Create `requirements.txt` and `requirements-dev.txt`
 86 | **Priority:** P1
 87 | 
 88 | ---
 89 | 
 90 | ### 6. Path Handling Uses os.path Instead of pathlib
 91 | **Files:** All Python files (11 files)
 92 | 
 93 | **Impact:** Code is less readable and more error-prone
 94 | **Fix:** Migrate to `pathlib.Path` throughout
 95 | **Priority:** P1
 96 | 
 97 | ---
 98 | 
 99 | ## Medium Priority Issues (P2)
100 | 
101 | ### 7. No Linux-Specific Testing
102 | **Impact:** Can't verify Linux compatibility
103 | **Fix:** Add GitHub Actions with Ubuntu runner
104 | **Priority:** P2
105 | 
106 | ---
107 | 
108 | ### 8. Log File Paths May Differ
109 | **File:** `src/logger.ts:13`
110 | ```typescript
111 | const DEFAULT_LOG_DIR = join(os.homedir(), '.kicad-mcp', 'logs');
112 | ```
113 | 
114 | **Impact:** `.kicad-mcp` is okay for Linux, but best practice is `~/.config/kicad-mcp`
115 | **Fix:** Use XDG Base Directory spec on Linux
116 | **Priority:** P2
117 | 
118 | ---
119 | 
120 | ### 9. No Bash/Shell Scripts for Linux
121 | **Impact:** Manual setup is harder on Linux
122 | **Fix:** Create `install.sh` and `run.sh` scripts
123 | **Priority:** P2
124 | 
125 | ---
126 | 
127 | ## Low Priority Issues (P3)
128 | 
129 | ### 10. TypeScript Build Uses Windows Conventions
130 | **File:** `package.json`
131 | 
132 | **Impact:** Works but could be more Linux-friendly
133 | **Fix:** Add platform-specific build scripts
134 | **Priority:** P3
135 | 
136 | ---
137 | 
138 | ## Positive Findings ✅
139 | 
140 | ### What's Already Good:
141 | 
142 | 1. **TypeScript Path Handling** - Uses `path.join()` and `os.homedir()` correctly
143 | 2. **Node.js Dependencies** - All cross-platform
144 | 3. **JSON Communication** - Platform-agnostic
145 | 4. **Python Base** - Python 3 works identically on all platforms
146 | 
147 | ---
148 | 
149 | ## Recommended Fixes - Priority Order
150 | 
151 | ### **Week 1 - Critical Fixes (P0)**
152 | 
153 | 1. **Create Platform-Specific Config Templates**
154 |    ```bash
155 |    config/
156 |    ├── linux-config.example.json
157 |    ├── windows-config.example.json
158 |    └── macos-config.example.json
159 |    ```
160 | 
161 | 2. **Fix Python Path Detection**
162 |    ```python
163 |    # Detect platform and set appropriate paths
164 |    import platform
165 |    import sys
166 |    from pathlib import Path
167 | 
168 |    if platform.system() == "Windows":
169 |        kicad_paths = [Path(sys.executable).parent / "Lib" / "site-packages"]
170 |    else:  # Linux/Mac
171 |        kicad_paths = [Path(sys.executable).parent / "lib" / "python3.X" / "site-packages"]
172 |    ```
173 | 
174 | 3. **Update Library Search Path Logic**
175 |    ```python
176 |    def get_kicad_library_paths():
177 |        """Auto-detect KiCAD library paths based on platform"""
178 |        system = platform.system()
179 |        if system == "Windows":
180 |            return ["C:/Program Files/KiCad/*/share/kicad/symbols/*.kicad_sym"]
181 |        elif system == "Linux":
182 |            return ["/usr/share/kicad/symbols/*.kicad_sym"]
183 |        elif system == "Darwin":  # macOS
184 |            return ["/Applications/KiCad/KiCad.app/Contents/SharedSupport/symbols/*.kicad_sym"]
185 |    ```
186 | 
187 | ### **Week 1 - High Priority (P1)**
188 | 
189 | 4. **Create requirements.txt**
190 |    ```txt
191 |    # requirements.txt
192 |    kicad-skip>=0.1.0
193 |    Pillow>=9.0.0
194 |    cairosvg>=2.7.0
195 |    colorlog>=6.7.0
196 |    ```
197 | 
198 | 5. **Add Linux Installation Documentation**
199 |    - Ubuntu/Debian instructions
200 |    - Fedora/RHEL instructions
201 |    - Arch Linux instructions
202 | 
203 | 6. **Migrate to pathlib**
204 |    - Convert all `os.path` calls to `Path`
205 |    - More Pythonic and readable
206 |

  1 | # KiCAD Footprint Library Integration
  2 | 
  3 | **Status:** ✅ COMPLETE (Week 2 - Component Library Integration)
  4 | **Date:** 2025-11-01
  5 | **Version:** 2.1.0-alpha
  6 | 
  7 | ## Overview
  8 | 
  9 | The KiCAD MCP Server now includes full footprint library integration, enabling:
 10 | - ✅ Automatic discovery of all installed KiCAD footprint libraries
 11 | - ✅ Search and browse footprints across all libraries
 12 | - ✅ Component placement using library footprints
 13 | - ✅ Support for both `Library:Footprint` and `Footprint` formats
 14 | 
 15 | ## How It Works
 16 | 
 17 | ### Library Discovery
 18 | 
 19 | The `LibraryManager` class automatically discovers footprint libraries by:
 20 | 
 21 | 1. **Parsing fp-lib-table files:**
 22 |    - Global: `~/.config/kicad/9.0/fp-lib-table`
 23 |    - Project-specific: `project-dir/fp-lib-table`
 24 | 
 25 | 2. **Resolving environment variables:**
 26 |    - `${KICAD9_FOOTPRINT_DIR}` → `/usr/share/kicad/footprints`
 27 |    - `${K IPRJMOD}` → project directory
 28 |    - Supports custom paths
 29 | 
 30 | 3. **Indexing footprints:**
 31 |    - Scans `.kicad_mod` files in each library
 32 |    - Caches results for performance
 33 |    - Provides fast search capabilities
 34 | 
 35 | ### Supported Formats
 36 | 
 37 | **Library:Footprint format (recommended):**
 38 | ```json
 39 | {
 40 |   "componentId": "Resistor_SMD:R_0603_1608Metric"
 41 | }
 42 | ```
 43 | 
 44 | **Footprint-only format (searches all libraries):**
 45 | ```json
 46 | {
 47 |   "componentId": "R_0603_1608Metric"
 48 | }
 49 | ```
 50 | 
 51 | ## New MCP Tools
 52 | 
 53 | ### 1. `list_libraries`
 54 | 
 55 | List all available footprint libraries.
 56 | 
 57 | **Parameters:** None
 58 | 
 59 | **Returns:**
 60 | ```json
 61 | {
 62 |   "success": true,
 63 |   "libraries": ["Resistor_SMD", "Capacitor_SMD", "LED_SMD", ...],
 64 |   "count": 153
 65 | }
 66 | ```
 67 | 
 68 | ### 2. `search_footprints`
 69 | 
 70 | Search for footprints matching a pattern.
 71 | 
 72 | **Parameters:**
 73 | ```json
 74 | {
 75 |   "pattern": "*0603*",  // Supports wildcards
 76 |   "limit": 20           // Optional, default: 20
 77 | }
 78 | ```
 79 | 
 80 | **Returns:**
 81 | ```json
 82 | {
 83 |   "success": true,
 84 |   "footprints": [
 85 |     {
 86 |       "library": "Resistor_SMD",
 87 |       "footprint": "R_0603_1608Metric",
 88 |       "full_name": "Resistor_SMD:R_0603_1608Metric"
 89 |     },
 90 |     ...
 91 |   ]
 92 | }
 93 | ```
 94 | 
 95 | ### 3. `list_library_footprints`
 96 | 
 97 | List all footprints in a specific library.
 98 | 
 99 | **Parameters:**
100 | ```json
101 | {
102 |   "library": "Resistor_SMD"
103 | }
104 | ```
105 | 
106 | **Returns:**
107 | ```json
108 | {
109 |   "success": true,
110 |   "library": "Resistor_SMD",
111 |   "footprints": ["R_0402_1005Metric", "R_0603_1608Metric", ...],
112 |   "count": 120
113 | }
114 | ```
115 | 
116 | ### 4. `get_footprint_info`
117 | 
118 | Get detailed information about a specific footprint.
119 | 
120 | **Parameters:**
121 | ```json
122 | {
123 |   "footprint": "Resistor_SMD:R_0603_1608Metric"
124 | }
125 | ```
126 | 
127 | **Returns:**
128 | ```json
129 | {
130 |   "success": true,
131 |   "footprint_info": {
132 |     "library": "Resistor_SMD",
133 |     "footprint": "R_0603_1608Metric",
134 |     "full_name": "Resistor_SMD:R_0603_1608Metric",
135 |     "library_path": "/usr/share/kicad/footprints/Resistor_SMD.pretty"
136 |   }
137 | }
138 | ```
139 | 
140 | ## Updated Component Placement
141 | 
142 | The `place_component` tool now uses the library system:
143 | 
144 | ```json
145 | {
146 |   "componentId": "Resistor_SMD:R_0603_1608Metric",  // Library:Footprint format
147 |   "position": {"x": 50, "y": 40, "unit": "mm"},
148 |   "reference": "R1",
149 |   "value": "10k",
150 |   "rotation": 0,
151 |   "layer": "F.Cu"
152 | }
153 | ```
154 | 
155 | **Features:**
156 | - ✅ Automatic footprint discovery across all libraries
157 | - ✅ Helpful error messages with suggestions
158 | - ✅ Supports KiCAD 9.0 API (EDA_ANGLE, GetFPIDAsString)
159 | 
160 | ## Example Usage (Claude Code)
161 | 
162 | **Search for a resistor footprint:**
163 | ```
164 | User: "Find me a 0603 resistor footprint"
165 | 
166 | Claude: [uses search_footprints tool with pattern "*R_0603*"]
167 |   Found: Resistor_SMD:R_0603_1608Metric
168 | ```
169 | 
170 | **Place a component:**
171 | ```
172 | User: "Place a 10k 0603 resistor at 50,40mm"
173 | 
174 | Claude: [uses place_component with "Resistor_SMD:R_0603_1608Metric"]
175 |   ✅ Placed R1: 10k at (50, 40) mm
176 | ```
177 | 
178 | **List available capacitors:**
179 | ```
180 | User: "What capacitor footprints are available?"
181 | 
182 | Claude: [uses list_library_footprints with "Capacitor_SMD"]
183 |   Found 103 capacitor footprints including:
184 |   - C_0402_1005Metric
185 |   - C_0603_1608Metric
186 |   - C_0805_2012Metric
187 |   ...
188 | ```
189 | 
190 | ## Configuration
191 | 
192 | ### Custom Library Paths
193 | 
194 | The system automatically detects KiCAD installations, but you can add custom libraries:
195 | 
196 | 1. **Via KiCAD Preferences:**
197 |    - Open KiCAD → Preferences → Manage Footprint Libraries
198 |    - Add your custom library paths
199 |    - The MCP server will automatically discover them
200 | 
201 | 2. **Via Project fp-lib-table:**
202 |    - Create `fp-lib-table` in your project directory
203 |    - Follow the KiCAD S-expression format
204 | 
205 | ### Supported Platforms
206 | 
207 | - ✅ **Linux:** `/usr/share/kicad/footprints`, `~/.config/kicad/9.0/`
208 | - ✅ **Windows:** `C:/Program Files/KiCAD/*/share/kicad/footprints`
209 | - ✅ **macOS:** `/Applications/KiCad/KiCad.app/Contents/SharedSupport/footprints`
210 | 
211 | ## KiCAD 9.0 API Compatibility
212 | 
213 | The library integration includes full KiCAD 9.0 API support:
214 | 
215 | ### Fixed API Changes:
216 | 1. ✅ `SetOrientation()` → now uses `EDA_ANGLE(degrees, DEGREES_T)`
217 | 2. ✅ `GetOrientation()` → returns `EDA_ANGLE`, call `.AsDegrees()`
218 | 3. ✅ `GetFootprintName()` → now `GetFPIDAsString()`
219 | 
220 | ### Example Fixes:
221 | **Old (KiCAD 8.0):**
222 | ```python
223 | module.SetOrientation(90 * 10)  # Decidegrees
224 | rotation = module.GetOrientation() / 10
225 | ```
226 | 
227 | **New (KiCAD 9.0):**
228 | ```python
229 | angle = pcbnew.EDA_ANGLE(90, pcbnew.DEGREES_T)
230 | module.SetOrientation(angle)
231 | rotation = module.GetOrientation().AsDegrees()
232 | ```
233 | 
234 | ## Implementation Details
235 | 
236 | ### LibraryManager Class
237 | 
238 | **Location:** `python/commands/library.py`
239 | 
240 | **Key Methods:**
241 | - `_load_libraries()` - Parse fp-lib-table files
242 | - `_parse_fp_lib_table()` - S-expression parser
243 | - `_resolve_uri()` - Handle environment variables
244 | - `find_footprint()` - Locate footprint in libraries
245 | - `search_footprints()` - Pattern-based search
246 | - `list_footprints()` - List library contents
247 | 
248 | **Performance:**
249 | - Libraries loaded once at startup
250 | - Footprint lists cached on first access
251 | - Fast search using Python regex
252 | - Minimal memory footprint
253 | 
254 | ### Integration Points
255 | 
256 | 1. **KiCADInterface (`kicad_interface.py`):**
257 |    - Creates `FootprintLibraryManager` on init
258 |    - Passes to `ComponentCommands`
259 |    - Routes library commands
260 | 
261 | 2. **ComponentCommands (`component.py`):**
262 |    - Uses `LibraryManager.find_footprint()`
263 |    - Provides suggestions on errors
264 |    - Supports both lookup formats
265 | 
266 | 3. **MCP Tools (`src/tools/index.ts`):**
267 |    - Exposes 4 new library tools
268 |    - Fully typed TypeScript interfaces
269 |    - Documented parameters
270 | 
271 | ## Testing
272 | 
273 | **Test Coverage:**
274 | - ✅ Library path discovery (Linux/Windows/macOS)
275 | - ✅ fp-lib-table parsing
276 | - ✅ Environment variable resolution
277 | - ✅ Footprint search and lookup
278 | - ✅ Component placement integration
279 | - ✅ Error handling and suggestions
280 | 
281 | **Verified With:**
282 | - KiCAD 9.0.5 on Ubuntu 24.04
283 | - 153 standard libraries (8,000+ footprints)
284 | - pcbnew Python API
285 | 
286 | ## Known Limitations
287 | 
288 | 1. **Library Updates:** Changes to fp-lib-table require server restart
289 | 2. **Custom Libraries:** Must be added via KiCAD preferences first
290 | 3. **Network Libraries:** GitHub-based libraries not yet supported
291 | 4. **Search Performance:** Linear search across all libraries (fast for <200 libs)
292 | 
293 | ## Future Enhancements
294 | 
295 | - [ ] Watch fp-lib-table for changes (auto-reload)
296 | - [ ] Support for GitHub library URLs
297 | - [ ] Fuzzy search for typo tolerance
298 | - [ ] Library metadata (descriptions, categories)
299 | - [ ] Footprint previews (SVG/PNG generation)
300 | - [ ] Most-used footprints caching
301 | 
302 | ## Troubleshooting
303 | 
304 | ### "No footprint libraries found"
305 | 
306 | **Cause:** fp-lib-table not found or empty
307 | 
308 | **Solution:**
309 | 1. Verify KiCAD is installed
310 | 2. Open KiCAD and ensure libraries are configured
311 | 3. Check `~/.config/kicad/9.0/fp-lib-table` exists
312 | 
313 | ### "Footprint not found"
314 | 
315 | **Cause:** Footprint doesn't exist or library not loaded
316 | 
317 | **Solution:**
318 | 1. Use `search_footprints` to find similar footprints
319 | 2. Check library name is correct
320 | 3. Verify library is in fp-lib-table
321 | 
322 | ### "Failed to load footprint"
323 | 
324 | **Cause:** Corrupt .kicad_mod file or permissions issue
325 | 
326 | **Solution:**
327 | 1. Check file permissions on library directories
328 | 2. Reinstall KiCAD libraries if corrupt
329 | 3. Check logs for detailed error

 90 | 
 91 | ## IPC Backend (Under Development)
 92 | 
 93 | We are currently implementing and testing the KiCAD 9.0 IPC API for real-time UI synchronization. This is experimental and may not work perfectly in all scenarios.
 94 | 
 95 | ### IPC-Capable Commands (21 total)
 96 | 
 97 | The following commands have IPC handlers implemented:
 98 | 
 99 | | Command | IPC Handler | Notes |
100 | |---------|-------------|-------|
101 | | `route_trace` | `_ipc_route_trace` | Implemented |
102 | | `add_via` | `_ipc_add_via` | Implemented |
103 | | `add_net` | `_ipc_add_net` | Implemented |
104 | | `delete_trace` | `_ipc_delete_trace` | Falls back to SWIG |
105 | | `get_nets_list` | `_ipc_get_nets_list` | Implemented |
106 | | `add_copper_pour` | `_ipc_add_copper_pour` | Implemented |
107 | | `refill_zones` | `_ipc_refill_zones` | Implemented |
108 | | `add_text` | `_ipc_add_text` | Implemented |
109 | | `add_board_text` | `_ipc_add_text` | Implemented |
110 | | `set_board_size` | `_ipc_set_board_size` | Implemented |
111 | | `get_board_info` | `_ipc_get_board_info` | Implemented |
112 | | `add_board_outline` | `_ipc_add_board_outline` | Implemented |
113 | | `add_mounting_hole` | `_ipc_add_mounting_hole` | Implemented |
114 | | `get_layer_list` | `_ipc_get_layer_list` | Implemented |
115 | | `place_component` | `_ipc_place_component` | Hybrid (SWIG+IPC) |
116 | | `move_component` | `_ipc_move_component` | Implemented |
117 | | `rotate_component` | `_ipc_rotate_component` | Implemented |
118 | | `delete_component` | `_ipc_delete_component` | Implemented |
119 | | `get_component_list` | `_ipc_get_component_list` | Implemented |
120 | | `get_component_properties` | `_ipc_get_component_properties` | Implemented |
121 | | `save_project` | `_ipc_save_project` | Implemented |
122 | 
123 | ### How IPC Works
124 | 
125 | When KiCAD is running with IPC enabled:
126 | 1. Commands check if IPC is connected
127 | 2. If connected, use IPC handler for real-time UI updates
128 | 3. If not connected, fall back to SWIG API
129 | 
130 | **To enable IPC:**
131 | 1. KiCAD 9.0+ must be running
132 | 2. Enable IPC API: `Preferences > Plugins > Enable IPC API Server`
133 | 3. Have a board open in the PCB editor
134 | 
135 | ### Known Limitations
136 | 
137 | - KiCAD must be running for IPC to work
138 | - Some commands may not work as expected (still testing)
139 | - Footprint loading uses hybrid approach (SWIG for library, IPC for placement)
140 | - Delete trace falls back to SWIG (IPC API limitation)
141 | 
142 | ---
143 | 
144 | ## What Needs Work
145 | 
146 | ### Minor Issues (NON-BLOCKING)
147 | 
148 | **1. get_board_info layer constants**
149 | - Error: `AttributeError: 'BOARD' object has no attribute 'LT_USER'`
150 | - Impact: Low (informational command only)
151 | - Workaround: Use `get_project_info` or read components directly
152 | 
153 | **2. Zone filling via SWIG**
154 | - Copper pours created but not filled automatically via SWIG
155 | - Cause: SWIG API segfault when calling `ZONE_FILLER`
156 | - Workaround: Use IPC backend or zones are filled when opened in KiCAD UI
157 | 
158 | **3. UI manual reload (SWIG mode)**
159 | - User must manually reload to see MCP changes when using SWIG
160 | - Impact: Workflow friction
161 | - Workaround: Use IPC backend for automatic updates
162 | 
163 | ---
164 | 
165 | ## Architecture Status
166 | 
167 | ### SWIG Backend (File-based)
168 | - **Status:** Stable and functional
169 | - **Pros:** No KiCAD process required, works offline, reliable
170 | - **Cons:** Requires manual file reload for UI updates, no zone filling
171 | - **Use Case:** Offline work, automated pipelines, batch operations
172 | 
173 | ### IPC Backend (Real-time)
174 | - **Status:** Under active development and testing
175 | - **Pros:** Real-time UI updates, no file I/O for many operations, zone filling works
176 | - **Cons:** Requires KiCAD running, experimental
177 | - **Use Case:** Interactive design sessions, paired programming with AI
178 | 
179 | ### Hybrid Approach
180 | The server automatically selects the best backend:
181 | - IPC when KiCAD is running with IPC enabled
182 | - SWIG fallback when IPC is unavailable
183 |
