This page lists every package in the MDK monorepo. Core is the Kernel, the Gateway, and the runtimes around them. Extensions are the Workers and
Gateway plugins that connect MDK to hardware, pools, and agents. UI is the browser toolkit, and Tools are what you develop with.
Availability says how you get a package:
workspace: private to the monorepo, used from a clone
publishable: not marked private, so it can be published to a registry
Injectable operator Co-pilot chat UI for the MDK agent gateway plugin. Streams the six-event agent contract over SSE and renders it as a docked panel or a full-page route
MDK Developer Skill Suite — Agent Skills (SKILL.md) bundle assembled from the MDK monorepo's real artifacts and versioned to track the MDK release line. Copy-only assembler: each library owns its artifacts, this package curates them into dist/skills/ and installs them flat into .cursor/skills/ or .claude/skills/
