MCP Servers

prioritization

An MCP server that provides a drag-and-drop UI for prioritizing list items, allowing users to reorder items interactively and send the prioritized list back to the chat. It supports MCP Apps UI rendering and falls back to text instructions for hosts without UI support.

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. ....

Try the deployed server

A live instance runs at https://mcp-prioritization.netlify.app/mcp — add it to Claude as a custom connector (Customize → Connectors → Add → Add custom connector → Remote MCP server URL; details in docs/claude.md).

Usage of the HTTP version of the MCP app: the human_prioritization tool renders a drag-and-drop list in the Claude chat

Example queries to force the MCP tool to be picked up:

List top 10 biggest cities in Lithuania
Let me prioritize cities to visit

Requires at least a Sonnet-tier model — Haiku did not call the tool in testing.

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

Quick test

npx @modelcontextprotocol/inspector --cli npx tsx src/stdio.ts --method tools/list | jq .
