Self-hosted artifact publishing: POST HTML/JSX/Markdown/zip, get an unguessable URL on your domain
Artifacts MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Self-hosted artifact publishing: POST HTML/JSX/Markdown/zip, get an unguessable URL on your domain.
Self-hosted, Claude-style artifact publishing
AI assistants produce a lot of shareable output: dashboards, prototypes, reports, small apps. Claude's hosted artifacts work well, but the URLs live on someone else's infrastructure. This is the self-hosted version, about 1,100 lines. You POST content, it serves the rendered result at an unguessable URL on a domain you control.
Once Artifacts is connected, these are the calls the assistant has available:
Agent — native, human-friendly.** A built-in MCP server lets Claude Code, Codex, or any MCP client publish with one tool call. Humans get a drag-and-drop webTwo — tier auth.** An admin logs into the dashboard with a password; CLI and MCP carry scoped, revocable API keys (read / publish / full)Abuse — resistant.** Login and unlock endpoints are rate-limited per client IP (failures only), and password hashing runs off the event loop, so a burst ofBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 2 environment variables: ARTIFACTS_API_KEY, BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Artifacts's toolset — Agent, Two, Abuse — is a fair guide to whether it matches your workflow. It is maintained by kuyazee; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
| Tool | What it does |
|---|---|
| Agent | native, human-friendly.** A built-in MCP server lets Claude Code, Codex, or any MCP client publish with one tool call. Humans get a drag-and-drop web UI at / (behind an admin login) and a [CLI](docs/cli.md). |
| Two | tier auth.** An admin logs into the dashboard with a password; CLI and MCP carry scoped, revocable [API keys](docs/auth.md) (read / publish / full) with optional expiry, so you never share one master secret. |
| Abuse | resistant.** Login and unlock endpoints are rate-limited per client IP (failures only), and password hashing runs off the event loop, so a burst of guesses slows those two routes instead of stalling the server. Set TRUST |
| Variable | Description | Required |
|---|---|---|
| ARTIFACTS_API_KEY | Credential the server authenticates with. | Yes |
| BASE_URL | Endpoint or connection string the server talks to. | Yes |
