PreviewShipCAUTION
Turn HTML, static build output, Markdown, or PDF files into shareable preview URLs. Direct upload, CLI, VS Code, and MCP workflows.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
Version delivery records: 2.0.1 — background content review and automatic remediation.
Deploy React/Vue/Vite/Next build output, HTML, Markdown, and PDF documents from your editor, terminal, AI agent, or browser and get fixed preview URLs.
PreviewShip is a frontend preview deployment platform for developers and AI-assisted workflows. Upload browser-ready build output such as dist, build, out, or public, publish a single HTML, Markdown, or PDF file, paste generated HTML, or let an AI coding agent deploy a static artifact and return a shareable PreviewShip URL in seconds.
PreviewShip is not a source-code build platform. For React, Vue, Vite, Next, Astro, Svelte, Angular, or Nuxt projects, build first and deploy the generated static output folder or zip with index.html. Single HTML, Markdown, and PDF files work directly.

Questions
What is the PreviewShip MCP server?
Turn HTML, static build output, Markdown, or PDF files into shareable preview URLs. Direct upload, CLI, VS Code, and MCP workflows.
What tools does PreviewShip expose?
12 in total: 9 read-only, 2 that write, and 1 that can delete or overwrite (delete_project). Every one is listed on this page with its risk.
Is PreviewShip safe to connect to an agent?
With care. The audit graded it C (79/100) and found 25 things worth knowing before you trust this server, listed below with the exact line each was found on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does PreviewShip need?
It reads PREVIEWSHIP_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does PreviewShip run?
It speaks stdio, so it runs as a local process your client starts.
How current is this page?
The grade is for one exact copy of the source (20ac27aa25af), read on 2026-10-12. The repository is watched and re-audited when it changes.
