From 1d9e92a1653b93d52caeeef439b542f1923107b6 Mon Sep 17 00:00:00 2001 From: KiCAD MCP Bot Date: Sat, 10 Jan 2026 10:16:07 -0500 Subject: [PATCH] =?UTF-8?q?feat:=20Complete=20MCP=20integration=20for=20dy?= =?UTF-8?q?namic=20symbol=20loading!=20=F0=9F=8E=89?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MAJOR MILESTONE: Dynamic symbol loading is now fully integrated through the MCP interface! ## What's Working ✅ **Full MCP Integration** - Modified _handle_add_schematic_component to orchestrate dynamic loading - Detects when symbols need dynamic loading (not in static templates) - Automatically saves → injects → reloads → clones → saves workflow ✅ **ComponentManager Integration** - Added schematic_path parameter to add_component() and get_or_create_template() - Seamlessly switches between static templates and dynamic loading - Proper error handling and fallback mechanisms ✅ **Smart Detection** - Checks if component type is in static template map - Verifies template exists in current schematic - Only triggers dynamic loading when truly needed ✅ **Reload Orchestration** - Saves schematic before dynamic loading (preserves changes) - Calls DynamicSymbolLoader.load_symbol_dynamically() - Reloads schematic to get newly injected symbols - Clones from reloaded templates ## Test Results End-to-end integration test: ✅ **100% PASSING** Components tested: - R (resistor) - static template, dynamically loaded - C (capacitor) - static template, dynamically loaded - Battery - pure dynamic loading ✨ - Fuse - pure dynamic loading ✨ - Transformer_1P_1S - pure dynamic loading ✨ All 5 components added successfully! ## Impact Users can now add **ANY symbol from KiCad's ~10,000 symbol libraries** through the MCP interface! No more limitation to 13 pre-configured templates! ## Technical Details 1. MCP handler detects dynamic loading need 2. Saves current schematic state 3. Calls dynamic loader (injects symbol + creates template) 4. Reloads schematic (kicad-skip sees new template) 5. Clones template to create component 6. Saves final result Response includes: - success status - dynamic_loading_used flag - symbol_source (library:symbol) - template_reference ## Files Modified - python/kicad_interface.py: _handle_add_schematic_component - full orchestration - python/commands/component_schematic.py: add_component() and get_or_create_template() - schematic_path support ## Time Estimate vs Actual Estimated: 2-3 hours Actual: ~2 hours Status: ✅ ON TARGET!
