- Add PathValidator class for preventing path traversal attacks
- Add SecureSubprocessRunner for safe command execution
- Replace unsafe XML parsing with defusedxml for security
- Add comprehensive input validation tools for circuit generation
- Include security dependencies (defusedxml, bandit) in pyproject.toml
- Add security scanning job to CI/CD pipeline
- Add comprehensive test coverage for security utilities
- Add timeout constants for safe operation limits
- Add boundary validation for component positioning
This establishes a strong security foundation for the KiCad MCP server
by implementing defense-in-depth security measures across all input
vectors and external process interactions.

This commit introduces a new circuit pattern recognition system that can
automatically identify common circuit patterns in KiCad schematics, including:
- Power supply circuits (linear regulators, switching converters)
- Amplifier circuits (op-amps, transistor amplifiers)
- Filter circuits (passive and active)
- Oscillator circuits (crystal, RC, IC-based)
- Digital interfaces (I2C, SPI, UART, USB)
- Microcontroller circuits
- Sensor interfaces
The implementation includes:
- Pattern recognition algorithms for common components
- Component value extraction and normalization utilities
- MCP tools for running pattern analysis
- MCP resources for displaying formatted results
- Comprehensive documentation
Users can easily extend the pattern recognition by adding new component
patterns or circuit recognition functions.
- Implement schematic netlist parser with S-expression parsing
- Create netlist tools for extraction and connection analysis
- Add resources for netlist and component connection reporting
- Include documentation with usage guide and troubleshooting
- Register new tools and resources in server configuration
This enables extracting component connections from KiCad schematics
and analyzing connectivity between components.
- Added environment variable support for configuring KiCad project search paths
- Implemented auto-detection of common project directories (~/pcb, ~/Electronics, etc.)
- Created .env file support for user-friendly configuration
- Added utility module for environment variable loading and management
- Updated documentation with detailed configuration options and troubleshooting steps
- Improved logging to help diagnose path-related issues
- Removed hardcoded paths to make the MCP server more generally usable
This commit implements comprehensive DRC support including:
- DRC check tool integration with both pcbnew Python module and CLI fallback
- Detailed DRC reports as resources with violation categorization
- Historical tracking of DRC results with visual trend analysis
- Comparison between current and previous DRC runs
- New prompt templates for fixing violations and custom design rules
- Full documentation in drc_guide.md
The DRC system helps users track their progress over time, focusing on the
most critical design rule violations as they improve their PCB designs.
