Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Self-hosted artifact publishing: POST HTML/JSX/Markdown/zip, get an unguessable URL on your domain
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Dashboard: publish, group by project, and manage
A published artifact served with the viewer topbar
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.
It runs as one container with a single admin account and, by default, no database. Each artifact is a directory of plain files under /data, so backing up that directory backs up everything. On hosts that wipe local disk on restart, point it at durable external storage instead (an S3-compatible bucket, a git remote, or Postgres) by setting STORAGE_BACKEND. See deploying.
/ (behind an admin login) and a CLI.read / publish / full) with optional expiry, so you never share one master secret.private, shared through a signed capability link (?k=…) you can rotate to revoke. Switch any artifact to public (anyone with the bare link) or password-protected. Nothing is discoverable by default: unguessable slugs, noindex everywhere. See visibility.?raw=1 serves the bare content. Redirects are never framed.mermaid code block is drawn as a diagram that follows the theme. See docs/formats.md..bpmn download. The XML is checked on publish, and a file with no diagram layout gets one drawn for it, pools and lanes included, so an agent can write the process and leave the coordinates to the server. See docs/formats.md.type: "redirect" turns a slug into a short link that answers an HTTP 301 at the server, where other hosts fall back to a JavaScript bounce. The target must be an absolute http(s) URL and cannot carry credentials, and the response is uncacheable, so repointing the slug takes effect on the next visit. Repoint one from the row menu in the dashboard, or with a PUT. Read the cost of running an open redirector on your domain first: docs/formats.md. . The row menu writes the tag for you, pointing at ?raw=1 so the frame holds the artifact and not a second toolbar. Private and password-protected artifacts stay unembeddable on purpose, and the unlock prompt refuses to be framed at all. See docs/embedding.md.GET /api/artifacts/:slug/qr, or artifacts qr . SVG or PNG, generated in-process: no QR library, no third-party image service, nothing about your artifacts leaves the box. See the API reference.TRUST_PROXY for the real client IP behind Cloudflare or a reverse proxy. See deploying.Clone, configure, start:
git clone https://github.com/anvilnine/artifacts && cd artifacts
cp .env.example .env # set ARTIFACTS_API_KEY (openssl rand -hex 32) and BASE_URL docker compose up -d
Or skip the clone and run the image directly:
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/anvilnine/artifacts:latest
Publish something:
curl -s -X POST https://artifacts.example.com/api/artifacts \
-H "Authorization: Bearer $ARTIFACTS_API_KEY" \ -H "Content-Type: application/json" \ -d '{"content": " hello ", "type": "html", "slug": "hello", "tags": ["demo"]}'
Let Claude Code publish for you:
claude mcp add --transport http artifacts https://artifacts.example.com/mcp \
--header "Authorization: Bearer ${ARTIFACTS_API_KEY}" --scope user

npm install
cp .env.example .env # any ARTIFACTS_API_KEY works locally, e.g. "test" npm run dev
The end-to-end suite is one shell script:
bash .github/workflows/smoke.sh http://localhost:3000 <your-key>
A few cases cannot be reached over HTTP, such as a hand-edited auth.json. Those run as unit tests on node's built-in runner, no server needed:
npm test
That covers the dashboard too. dashboard-check.mjs fetches /, parses the inline script in public/index.html, and checks that every element the script grabs by id is still in the markup. It runs no browser, so it catches a syntax error or a deleted element but not a runtime error.
PRs welcome. See CONTRIBUTING.md.
Self-hosting is the product, and the open source version stays complete. If you would rather not run a server, Anvil Nine is building a managed version: same publishing flow, custom domains, backups handled for you. A waitlist page opens with the first cloud announcement; watch this repo's releases until then.
Uploaded HTML runs in the browser. That is the whole point, so the model is built to contain it:
noindex, but there is no listing to browse. Don't publish secrets.publish scope gets a 256 kB body parser instead of the 10 MB one, and a cap of 20 large bodies a minute per client IP, both checked before the body is parsed. Put a CDN or edge limiter in front for volumetric attacks.Full threat model in SECURITY.md.
