From 995dfd57c1ca11b14009b2bc7520756a392160e0 Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Mon, 11 Aug 2025 15:57:46 -0600 Subject: [PATCH] Add comprehensive advanced KiCad features and fix MCP compatibility issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Implement 3D model analysis and mechanical constraints checking - Add advanced DRC rule customization for HDI, RF, and automotive applications - Create symbol library management with analysis and validation tools - Implement PCB layer stack-up analysis with impedance calculations - Fix Context parameter validation errors causing client failures - Add enhanced tool annotations with examples for better LLM compatibility - Include comprehensive test coverage improvements (22.21% coverage) - Add CLAUDE.md documentation for development guidance New Advanced Tools: • 3D model analysis: analyze_3d_models, check_mechanical_constraints • Advanced DRC: create_drc_rule_set, analyze_pcb_drc_violations • Symbol management: analyze_symbol_library, validate_symbol_library • Layer analysis: analyze_pcb_stackup, calculate_trace_impedance 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 124 +++ kicad_mcp/__init__.py | 3 +- kicad_mcp/context.py | 47 +- kicad_mcp/prompts/bom_prompts.py | 15 +- kicad_mcp/prompts/drc_prompt.py | 5 +- kicad_mcp/prompts/pattern_prompts.py | 19 +- kicad_mcp/prompts/templates.py | 9 +- kicad_mcp/resources/bom_resources.py | 120 ++- kicad_mcp/resources/drc_resources.py | 120 +-- kicad_mcp/resources/files.py | 25 +- kicad_mcp/resources/netlist_resources.py | 164 +-- kicad_mcp/resources/pattern_resources.py | 137 +-- kicad_mcp/resources/projects.py | 21 +- kicad_mcp/server.py | 64 +- kicad_mcp/tools/advanced_drc_tools.py | 446 +++++++++ kicad_mcp/tools/analysis_tools.py | 21 +- kicad_mcp/tools/bom_tools.py | 518 +++++----- kicad_mcp/tools/drc_impl/cli_drc.py | 73 +- kicad_mcp/tools/drc_tools.py | 92 +- kicad_mcp/tools/export_tools.py | 51 +- kicad_mcp/tools/layer_tools.py | 650 ++++++++++++ kicad_mcp/tools/model3d_tools.py | 334 +++++++ kicad_mcp/tools/netlist_tools.py | 269 ++--- kicad_mcp/tools/pattern_tools.py | 123 ++- kicad_mcp/tools/project_tools.py | 16 +- kicad_mcp/tools/symbol_tools.py | 549 ++++++++++ kicad_mcp/utils/advanced_drc.py | 446 +++++++++ kicad_mcp/utils/component_layout.py | 36 + kicad_mcp/utils/component_utils.py | 162 +-- kicad_mcp/utils/coordinate_converter.py | 29 + kicad_mcp/utils/drc_history.py | 88 +- kicad_mcp/utils/env.py | 64 +- kicad_mcp/utils/kicad_api_detection.py | 22 +- kicad_mcp/utils/kicad_utils.py | 72 +- kicad_mcp/utils/layer_stackup.py | 559 +++++++++++ kicad_mcp/utils/model3d_analyzer.py | 404 ++++++++ kicad_mcp/utils/netlist_parser.py | 366 +++---- kicad_mcp/utils/pattern_recognition.py | 1159 +++++++++++++--------- kicad_mcp/utils/symbol_library.py | 545 ++++++++++ kicad_mcp/utils/temp_dir_manager.py | 9 +- main.py | 3 +- start.sh | 2 + tests/unit/test_config.py | 228 +++++ tests/unit/test_context.py | 229 +++++ tests/unit/test_server.py | 367 +++++++ tests/unit/utils/test_component_utils.py | 634 ++++++++++++ tests/unit/utils/test_file_utils.py | 331 ++++++ tests/unit/utils/test_kicad_cli.py | 413 ++++++++ 48 files changed, 8403 insertions(+), 1780 deletions(-) create mode 100644 CLAUDE.md create mode 100644 kicad_mcp/tools/advanced_drc_tools.py create mode 100644 kicad_mcp/tools/layer_tools.py create mode 100644 kicad_mcp/tools/model3d_tools.py create mode 100644 kicad_mcp/tools/symbol_tools.py create mode 100644 kicad_mcp/utils/advanced_drc.py create mode 100644 kicad_mcp/utils/component_layout.py create mode 100644 kicad_mcp/utils/coordinate_converter.py create mode 100644 kicad_mcp/utils/layer_stackup.py create mode 100644 kicad_mcp/utils/model3d_analyzer.py create mode 100644 kicad_mcp/utils/symbol_library.py create mode 100755 start.sh create mode 100644 tests/unit/test_config.py create mode 100644 tests/unit/test_context.py create mode 100644 tests/unit/test_server.py create mode 100644 tests/unit/utils/test_component_utils.py create mode 100644 tests/unit/utils/test_file_utils.py create mode 100644 tests/unit/utils/test_kicad_cli.py diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 0000000..e96df0f --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,124 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## Development Commands + +### Essential Commands +- `make install` -
