-## Implementation Details - -The KiCAD MCP implementation uses a modular, maintainable architecture: - -### TypeScript MCP Server (Node.js) -- **kicad-server.ts**: The main server that implements the MCP protocol -- Uses STDIO transport for reliable communication with Cline -- Manages the Python process for KiCAD operations -- Handles command queuing, error recovery, and response formatting - -### Python Interface -- **kicad_interface.py**: The main Python interface that: - - Parses commands received as JSON via stdin - - Routes commands to the appropriate specialized handlers - - Returns results as JSON via stdout - - Handles errors gracefully with detailed information - -- **Modular Command Structure**: - - `commands/project.py`: Project creation, opening, saving - - `commands/schematic.py`: Schematic creation and management - - `commands/component_schematic.py`: Schematic component operations - - `commands/connection_schematic.py`: Wire and connection management - - `commands/library_schematic.py`: Symbol library integration - - `commands/board/`: Modular board manipulation functions - - `size.py`: Board size operations - - `layers.py`: Layer management - - `outline.py`: Board outline creation - - `view.py`: Visualization functions - - `commands/component.py`: PCB component placement and manipulation - - `commands/routing.py`: Trace routing and net management - - `commands/design_rules.py`: DRC and rule configuration - - `commands/export.py`: Output generation in various formats - -This architecture ensures that each aspect of PCB design is handled by specialized modules while maintaining a clean, consistent interface layer. +# Format code +npm run format +``` ## Troubleshooting -### Common Issues and Solutions +### Server Not Appearing in Client -**Problem: KiCAD MCP isn't showing up in Claude's tools** -- Make sure VSCode is completely restarted after updating the Cline MCP settings -- Verify the paths in the config are correct for your system -- Check that the `npm run build` completed successfully +**Symptoms:** MCP server doesn't show up in Claude Desktop or Cline -**Problem: Node.js errors when launching the server** -- Ensure you're using Node.js v18 or higher -- Try running `npm install` again to ensure all dependencies are properly installed -- Check the console output for specific error messages +**Solutions:** +1.

Check client logs for error messages -**Problem: Python errors or KiCAD commands failing** -- Verify that KiCAD 9.0 is properly installed -- Check that the PYTHONPATH in the configuration points to the correct location -- Try running a simple KiCAD Python script directly to ensure the pcbnew module is accessible +### Python Module Import Errors -**Problem: Claude can't find or load your KiCAD project** -- Use absolute paths when referring to project locations -- Ensure the user running VSCode has access permissions to the directories +**Symptoms:** `ModuleNotFoundError: No module named 'pcbnew'` + +**Solutions:** +1. Verify KiCAD installation: `python3 -c "import pcbnew"` +2. Check PYTHONPATH in configuration matches your KiCAD installation +3. Ensure KiCAD was installed with Python support + +### Tool Execution Failures + +**Symptoms:** Tools fail with unclear errors + +**Solutions:** +1. Check server logs: `~/.kicad-mcp/logs/kicad_interface.log` +2. Verify a project is loaded before running board operations +3. Ensure file paths are absolute, not relative +4. Check tool parameter types match schema requirements + +### Windows-Specific Issues + +**Symptoms:** Server fails to start on Windows + +**Solutions:** +1. Run automated diagnostics: `.\setup-windows.ps1` +2. Verify Python path uses double backslashes: `C:\\Program Files\\KiCad\\9.0` +3. Check Windows Event Viewer for Node.js errors +4.
