MCP

prevju has an MCP server at <APP_URL>/mcp. With it, Claude Code or Codex can create sites, upload drafts and give you the client link.

Connect

Create a token in the admin under MCP. The page generates the command with your token filled in, for Claude Code or Codex, for all projects or just the current one.

Claude Code (--scope user for all projects, --scope local for the current one):

claude mcp add --transport http --scope user prevju https://preview.example.com/mcp --header "Authorization: Bearer <token>"

Codex: add this to ~/.codex/config.toml (all projects) or .codex/config.toml in a trusted project. Keep the project file out of git, it contains the token.

[mcp_servers.prevju]
url = "https://preview.example.com/mcp"
http_headers = { "Authorization" = "Bearer <token>" }

A token has the same rights as the admin login. Create one per device so you can revoke them one by one.

Tools

Tool	What it does
get-compatibility	Returns What works. Agents call it before uploading
list-sites, get-site	Sites with link, password status and files
create-site	New site, optionally with a password
update-site	Rename, set or remove the password
write-files	Write generated text files (HTML, CSS, JS) directly
get-upload-url	Signed 15-minute URL to upload a zip or binary file with curl
delete-file, clear-files, delete-site	Destructive, no undo

For a new version of a draft, agents upload with replace: the live site switches over in one step and is never empty in between. A failed upload changes nothing.

Limits

• Zips and other binary files are uploaded with curl to a signed URL, so they need a client with a shell (Claude Code, Codex).
• Connectors in claude.ai and Claude Desktop need OAuth, which prevju doesn't support yet.
