MCP Prioritization

A "human prioritization" MCP server built with the official MCP TypeScript SDK v2 (@modelcontextprotocol/server@^2.0.0) and the MCP Apps extension: the human_prioritization tool ships an interactive ui:// drag-and-drop list that hosts like Claude Cowork render as a sandboxed iframe. Reorder the items, press "Send priorities to chat", and the ranked list comes back into the conversation as Prioritized: 1. ... 2. ....

Setup

Requires Node.js 26 (see .nvmrc) and uses TypeScript 7 (native compiler).

nvm use          # picks up .nvmrc
npm install
npm run typecheck   # tsc --noEmit
