Instant static hosting for agent-built websites
The fair opens at dusk.
Your AI agent builds a website. Carnival puts it online in seconds, on a free link that lasts 7 days.
How it works
Three steps. No code, no servers.
ADMIT ONE · 01
Connect
Add Carnival to Muse, then sign in with an email code.
ADMIT ONE · 02
Ask
Tell your agent: "Make a one-page website for my piano tuning business and put it on Carnival."
ADMIT ONE · 03
Share
You get a link like gilded-carousel-b4x9t.carnival-staging.page. It's live right away.
Paste this into a new Muse chat:
Connect Carnival as a custom connector. It is an MCP server at https://carnival-staging.dev/mcp (Streamable HTTP: POST JSON-RPC, protocol 2025-06-18, header "Accept: application/json" is fine; every reply is one JSON object; GET returning 405 means the server is up). Auth is OAuth 2.1 with PKCE and dynamic client registration: read https://carnival-staging.dev/.well-known/oauth-protected-resource/mcp, then the authorization-server metadata it lists, and use exactly those endpoints; never guess an endpoint. Give me the Connect button so I can sign in. Allowed host: carnival-staging.dev only. Then prove the connection by calling carnival_status and showing me the result. Read https://carnival-staging.dev/SKILL.md and follow its rules; before publishing anything, show me the file list and ask me to confirm.
Muse shows a card with an Allow button. Select it, then sign in to Carnival and choose Allow there too.

The rules of the fair
What the free plan gives you.
- 3 sites at a time. End one to make room for another.
- 7 days each. A clock shows how long each site has left.
- Then the lights go out. When time's up, the site goes offline and its files are deleted.
- Static files only. HTML, CSS, JavaScript, images and fonts. No servers, databases or passwords.
Permanent sites with your own domain are coming. Tell me when
What's not allowed
Carnival is for menus, opening hours, price lists and simple pages. Not for:
- Anything unlawful or harmful
- Phishing, scams, fraud or malware
- Sexually explicit content
- Pretending to be another person, business or brand
Need help? Ask your agent.
Your agent can check your sites, see how long each has left, and read the deploy log to find out why something didn't go up. Try: "Why didn't my Carnival site deploy?"
