- Four content types: HTML, JSX/TSX, Markdown, and zip static sites.
- MCP server at /mcp for AI agents (publish, update, disable, list, delete).
- Web UI with drag-and-drop upload and lifecycle management.
- Lifecycle controls: rename slugs, disable/enable, auto-expiry (410).
- Non-crawlable: noindex headers and deny-all robots.txt.
- Zip upload validation: requires index.html, static extensions only, rejects traversal/symlinks.
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Artifacts — self-hosted artifact publishing (HTML/JSX/Markdown/zip → unguessable URL)Command (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Deploy with Docker Compose, Docker, or bare Node (requires Node ≥22 and setting ARTIFACTS_API_KEY and BASE_URL environment variables). Then publish artifacts via curl, the included CLI (node cli.js), or MCP tools (e.g., publish_artifact). The web UI at / allows drag-and-drop management after authenticating with the API key.

Self-hosted, Claude-style artifact publishing. POST an HTML page, a React component, a Markdown doc, or a whole zipped static site — get back a public, unguessable, non-crawlable URL on your own domain. Built for coding agents (MCP server included) and humans (drag-and-drop web UI included).
Why
AI assistants generate a lot of shareable output — dashboards, prototypes, reports, little apps. Claude's hosted artifacts are great, but the URLs live on someone else's infrastructure. This is the ~600-line self-hosted version:
- One tiny Node service. Express + a handful of deps. No database, no accounts, no build step — artifacts are plain files under /data.
- Agent-native. Built-in MCP server (streamable HTTP), so Claude Code, Codex, or any MCP client can publish with one tool call. Everything is also a single curl.
- Private by default. Random unguessable slugs, noindex everywhere, bearer-token writes, optional expiry.
Features
- Four content types: HTML, JSX/TSX (single React component, rendered client-side via esm.sh — arbitrary npm imports, no build), Markdown (rendered server-side), and zip sites (multi-file static projects with images/CSS/JS).
- MCP server at /mcp — publish, update, rename, disable/enable, set expiry, list, delete.
- Web UI at / — drag-and-drop or paste to publish, manage everything, locked behind your API key.
- Lifecycle controls: rename slugs, disable without deleting (404), auto-expire (expiresAt → 410), delete.
- Non-crawlable: X-Robots-Tag: noindex, nofollow on every response, deny-all robots.txt.
- Zip uploads are validated before anything is stored: index.html required, static-only extension whitelist, traversal/symlink rejection, size and file-count limits.
Quickstart
docker compose (recommended)
git clone https://github.com/kuyazee/artifacts && cd artifacts
ARTIFACTS_API_KEY=$(openssl rand -hex 32) BASE_URL=https://artifacts.example.com docker compose up -d
docker
docker run -d -p 3000:3000 -v artifacts-data:/data \
-e ARTIFACTS_API_KEY=$(openssl rand -hex 32) \
-e BASE_URL=https://artifacts.example.com \
ghcr.io/kuyazee/artifacts:latest
bare node
npm ci
ARTIFACTS_API_KEY=$(openssl rand -hex 32) BASE_URL=https://artifacts.example.com node server.js
Then publish something:
```bash
curl -s -X POST https://artifacts.example.com/api/artifacts \
-H "Authorization: Bearer $ARTIFACTS_API_KEY" \
-H "Content-Type: application/json" \
-d '{"content": "<h1>hello</h1>", "type": "html", "slug": "hello"}'
