com.kernelcad/kernelcad
com.kernelcad/kernelcad in the official MCP registry.
Endpoint https://mcp.kernelcad.com/mcp. Source: github.com/w1ne/kernelCAD-web.
The registry describes it as: Agent-first CAD: editable .kcad.ts source, deterministic review, OpenCASCADE kernel.
We read its 71 tools on 2026-10-27. Nothing in them matched our tool-poisoning rules.
A clean read means these rules found nothing, not that the server is harmless. A server can change its tools at any time, which is why the index reads it again every week.

[](https://lazaretto.dev/mcp-registry/com-kernelcad-kernelcad)How this was checked
Lazaretto connects to the endpoint the way any MCP client does, asks the server to introduce itself and list its tools, and reads every name, description, parameter schema and server instruction for tool poisoning: hidden directive blocks, orders to read local secrets, parameters built to carry secrets or the conversation out, orders that redirect another server's tools, and invisible characters. It never calls a tool. What we found across the registry.
