Built on the MCP 2025-06-18 specification, this server provides comprehensive tool schemas and real-time project state access for intelligent PCB design workflows. ## Overview The [Model Context Protocol](https://modelcontextprotocol.io/) is an open standard from Anthropic that allows AI assistants to securely connect to external tools and data sources. This implementation provides a standardized bridge between AI assistants and KiCAD, enabling natural language control of PCB design operations. **Key Capabilities:** - 146 tools across 13 categories with JSON Schema validation - Keyword tool discovery via `search_tools` / `get_category_tools` - 8 dynamic resources exposing project state - Complete schematic workflow with 27 tools and dynamic symbol loading (~10,000 symbols) - Freerouting autorouter integration (Java, Docker, or Podman) - Custom footprint and symbol creation tools - JLCPCB parts integration with 2.5M+ component catalog and local library search - Datasheet enrichment via LCSC - Full MCP 2025-06-18 protocol compliance - Cross-platform support (Linux, Windows, macOS) - Real-time KiCAD UI integration via IPC API (experimental) - Comprehensive error handling and logging ## Try out Arduino MCP - now you can get Claude to help in the IDE, real time!: https://github.com/mixelpixx/arduino-ide ## What's New in v2.6.0 ### A session-killing bug is fixed Deleting anything from a board — a component, a trace, a board outline — worked exactly once. The next operation, even a pure read, failed with a `SwigPyObject` error, and only `close_project` then `open_project` recovered. `BOARD.Remove()` hands C++ ownership to Python, so dropping the reference ran a destructor on an object KiCad still pointed at, corrupting SWIG state process-wide. Six call sites were affected; all now use `BOARD.Delete()`. ### 10 new tools - **Vendor PCB import**: `import_pcb` converts PADS, Altium, Eagle, CADSTAR, Fabmaster, P-CAD, SolidWorks PCB and binary Cadence Allegro `.brd` files via KiCad 10's native importer. - **Hierarchical schematics**: `remove_hierarchical_sheet`, `set_sheet_property`, `get_sheet_properties`, and `hierarchical_place` for arranging footprints by schematic hierarchy. - **Schematic lint and repair**: `lint_offgrid` finds and safely snaps off-grid geometry that silently breaks junction placement; `repair_flat_symbols` fixes SnapEDA/SamacSys symbols that crash kicad-skip; `lint_schematic_cosmetic` tidies pin names and label orientation. - **Board origins**: `set_board_origin` / `get_board_origin`. ### Your `.kicad_pro` net classes stop disappearing Board saves no longer let pcbnew serialize a stale in-memory project model over your hand-edited net classes and `netclass_patterns`. Opening a project no longer rewrites the file at all. ### Breaking: schematic tools fail loudly on an unparseable sheet Tools that used to return partial or empty results now return a structured `schematic_load_failed` error naming the offending symbols. Silently skipping a broken sheet produced an incomplete pad-to-net map reported as success, which is worse. `repair_flat_symbols` fixes the usual cause.
