Set up Hoaster in Claude Desktop

Add Hoaster as an MCP server and Claude can publish pages, images, and other artifacts to the web for you — and hand you back a public URL — without ever leaving the conversation. Setup takes about a minute and there's no API key or token to copy.

Before you start

• Claude Desktop installed (macOS or Windows).

• A Hoaster account — you sign in through your browser during setup, so make sure you can. Create one if you haven't yet.

Your MCP server URL

This is the endpoint Claude connects to. You'll paste it once below.

    Connect and sign in

    Hoaster now appears under your connectors. Open it and click Connect. A browser window opens for you to sign in to Hoaster — approve it and you'll be sent back to Claude. No token to copy: Hoaster uses OAuth 2.1, so the sign-in stays in your browser.

    You're connected

    Claude confirms Connected to Hoaster and lists the tools it can now use — including publish. That's it, Hoaster is ready.

Check that it works

Start a new conversation and ask Claude to publish something. You never have to mention Hoaster by name — it has the tool now.

“Create a simple HTML page and publish it!”

Claude hands back a live hoaster.page URL once the page is online.
