- 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.

- Fix open_project tool for Linux compatibility (uses xdg-open).
- Force DRC tool to use kicad-cli due to kipy import errors, ensuring reliability.
- Correct thumbnail generation to use svg export via kicad-cli instead of unsupported png.
- Save generated thumbnails directly into the project directory.
- Remove debug logging added during troubleshooting.
- Update .gitignore to correctly ignore the .venv directory.
- Remove mcp.dev usage from documentation as a method for running the server.
- Remove obsolete python_path.py utility and deleted test file.
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
Implement proper context management in the KiCad MCP server:
Add dedicated context.py with typed KiCadAppContext class
Convert tools to access context instead of parameters
Implement caching for thumbnails
Add proper cleanup of resources on shutdown
Improve error handling with cancellation support
Implements a more reliable PCB thumbnail generation feature using two methods:
- Primary: pcbnew Python module for high-quality rendering
- Fallback: pcbnew_cli for environments without Python modules
Adds detailed progress reporting and comprehensive error handling.
Includes documentation in docs/thumbnail_guide.md.
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.
