Konnect *BETA Release

</div>

AI-assisted PCB design for KiCAD 10. Konnect is a native KiCAD plugin — a single Rust binary — that lets Claude and other AI assistants design schematics and PCBs through the Model Context Protocol (MCP).

187 tools across 18 on-demand toolsets. Schematic capture, PCB layout and routing, ERC/DRC, design-review audits, JLCPCB part search, Freerouting, reference circuits, and a full manufacturing export pipeline — with bundled skills and agents that teach Claude KiCAD conventions out of the box.

Status: beta. The core toolchain is tested and working, but this is a young release and it wants real-world mileage and review. Issues and PRs are welcome — see CONTRIBUTING.md and the naming conventions.

Why Konnect exists

Konnect is the successor to KiCAD-MCP-Server, a Python/TypeScript project that proved AI-driven PCB design works — and, in the process, showed exactly where that architecture runs out of road. Konnect was built to fix those specific problems:

The call path was too long. In the original server, a single tool call travels through TypeScript, schema validation, a spawned Python subprocess, JSON over stdin/stdout, a command router, and finally SWIG-generated C++ proxy objects before anything touches your board. That's four language and serialization boundaries, each with its own failure modes — subprocess lifecycle management, stdout parsing that filters out warnings KiCAD leaks into the stream, chunked-JSON reassembly. In Konnect, a tool call is a function call. One process, one language, no plumbing.

The dependency surface was enormous. Running the original means carrying Node.js and its npm tree, Python and its pip packa
