Sign in to your Tiiny Host account


There are two ways. Pick one.


  • Email code (any plan): The first time you publish, Claude asks for your Tiiny Host email address. We email you a one-time code, and you give it to Claude.
  • API key (Solo and above): Before clicking Add in step 7, go to Request Headers, click Add Header, choose x-api-key and paste your key. See How to generate your API key.

Your site is live. Ask Claude for changes and it'll update the same project rather than creating a new one.

Projects you publish this way count towards your plan's limits like any other upload.


If it doesn't connect


  • Check the URL: https://mcp.tiiny.host with nothing after it. A trailing slash is the usual cause.
  • No code arrived? Check your spam folder, and that you gave Claude the email on your Tiiny Host account.
  • Using an API key? Make sure it's your current one. Generating a new key replaces the old one.
  • Remove and re-add the connector. This clears most connection problems.
  • Still stuck? Email support@tiiny.host with the AI tool you're using and the exact error.


Other AI tools


Our MCP server works with any tool that supports custom MCP connectors. Add a custom connector pointing at https://mcp.tiiny.host; the menus differ by tool. For Grok, see How to connect Tiiny Host to Grok.
