ShareCube

ShareCube is an AI agent artifact review tool that publishes HTML and Markdown over MCP for team collaboration.

ShareCube is a review layer between AI agents and teams that turns agent output into team input. Agents publish HTML and Markdown artifacts to ShareCube over MCP using clients like Claude Code and Cursor. Teams can then comment on exact sentences with selection-anchored threads, edit artifacts in place, and share links that anyone can open in a browser. It is built for agent handoffs rather than chat logs, supporting projects with viewer, commenter, and editor roles. Features include full-text search across projects, scoped API keys, and share links with configurable visibility policies. It offers a free tier alongside Pro, Team, and Enterprise plans with flat monthly pricing.
