• Export schematics to PDF for documentation.

This addition completes the PCB design workflow, allowing AI assistants to help with both schematic capture and PCB layout in a single integrated environment.

Project Management:

• Create new KiCAD projects with customizable settings, specifying project names and directories using natural language commands.
• Open existing KiCAD projects directly by providing the file path.
• Save projects, optionally specifying new locations for organization and version control.
• Retrieve project metadata and properties, providing valuable context to the AI assistant.

Board Design:

• Set precise board dimensions using metric or imperial units, tailoring the board size to your specific requirements.
• Add custom board outlines, including rectangles, rounded rectangles, circles, and polygons, allowing for flexible board shapes.
• Create and manage board layers with various configurations, optimizing the board for signal routing and power distribution.
• Add mounting holes, text annotations, and other board features to enhance functionality and documentation.
• Visualize the current board state to ensure accurate design and placement.

Component Placement:

• Place components with specified footprints at precise locations on the board, ensuring accurate placement and alignment.

• Add vias, including blind and buried vias, to connect traces on different layers of the board.
• Create differential pair routes for high-speed signals, minimizing signal degradation and ensuring signal integrity.
• Generate copper pours (ground planes, power planes) to provide shielding, improve heat dissipation, and reduce impedance.
• Define net classes with specific design rules, ensuring that critical signals meet performance requirements.

Design Rules:

• Set global design rules for clearance, track width, and other parameters, ensuring that the design meets manufacturing constraints.
• Define specific rules for different net classes, tailoring the design rules to the requirements of critical signals.
• Run Design Rule Check (DRC) to validate the design and identify potential violations.
• View and manage DRC violations, allowing for quick identification and correction of design errors.

Export:

• Generate industry-standard Gerber files for fabrication, enabling seamless transfer of the design to manufacturing facilities.
• Export PDF documentation of the PCB, providing detailed information for assembly and testing.
• Create SVG vector graphics of the board, allowing for easy integration into documentation and presentations.
• Generate 3D models in STEP or VRML format, facilitating visualization and mechanical integration.
• Produce bill of materials (BOM) in various formats, streamlining the procurement and assembly process.

Core Architecture: A Modular and Maintainable Design

KiCAD MCP is built on a modular architecture that ensures maintainability and extensibility:

• TypeScript MCP Server (Node.js):
  • Implements the Anthropic Model Context Protocol specification for seamless communication with Claude and other compatible AI assistants.
  • Uses STDIO transport for reliable data exchange.
  • Manages the Python process for executing KiCAD operations.
  • Handles command queuing, error recovery, and response formatting to ensure reliable operation.
• Python Interface:
  • Parses commands received as JSON via stdin.
  • Routes commands to specialized handlers for efficient processing.
  • Returns results as JSON via stdout.
  • Handles errors gracefully with detailed information for debugging.
• Modular Command Structure: Functionality is organized by domains:
  • commands/project.py: Project creation, opening, and 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, layers, outline, view).
  • 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 modular design ensures that each aspect of PCB design is handled by specialized modules while maintaining a clean and consistent interface layer.
