Meet Konnect — the next generation

Konnect is this project rebuilt from scratch in Rust as a native KiCAD 10 plugin: a single binary with no runtime dependencies, built on KiCAD's official IPC API instead of SWIG, with 171 tools, bundled Claude skills and agents, design-review audits, and a manufacturing pipeline. It's where new development happens — licensed AGPL-3.0 (free for individuals and open source; commercial licenses available for businesses).

This Python/TypeScript server remains fully open (MIT) and maintained.

KiCAD MCP and Konnect works well with Nimrod

Nimrod is our web-research MCP server: quality-scored Google search, clean webpage extraction, and deep multi-source research. Design the board with Konnect while Nimrod pulls live parts availability, datasheets, and errata — no more guessing from year-old training data

Works with claude.ai, Claude Desktop, Claude Code, VS Code, and any MCP client
