Publish pages from Claude, ChatGPT, or any AI tool
Sign up free to get your MCP connector URL and start publishing in seconds.
MCP Connector
To connect the HTML Pub MCP connector, add the remote MCP server at https://mcp.htmlpub.com/mcp to Claude, ChatGPT, Claude Code, or Claude Desktop, then sign in with your HTML Pub account when prompted — it is OAuth-based, so no API key is needed. Once connected, your AI assistant can create, edit, and manage pages through 37 tools (create_page, edit_page, list_pages, and more).
The MCP connector is included on every plan, including Free. Free lets you build and preview pages; publishing a live, shareable URL requires a paid plan starting at $10/mo.
What is MCP?
The Model Context Protocol lets AI assistants use tools
The htmlpub MCP connector gives AI assistants like Claude the ability to publish, update, and manage HTML pages on your behalf. Instead of copying and pasting HTML, your AI assistant can publish directly to htmlpub.com with a single tool call.
One MCP connector works everywhere — Claude.ai, ChatGPT, Claude Code, and Claude Desktop. No API keys needed. Just sign in with your htmlpub account.

Frequently Asked Questions
How do I connect the HTML Pub MCP connector to Claude?
Add the remote MCP server at https://mcp.htmlpub.com/mcp, then sign in with your HTML Pub account when prompted. It uses OAuth, so no API key is required. Use the exact connect steps documented on this page for each client (Claude.ai, ChatGPT, Claude Code, Claude Desktop).
Do I need an API key to use the MCP connector?
No. The MCP connector is OAuth-based — you sign in with your HTML Pub account the first time you connect and authorize access, and no API key is needed. (A separate Bearer-key REST API is available, but only on the Pro and Business plans.)
How do I publish an HTML page from Claude?
Once the MCP connector is added, ask your AI assistant to publish a page in plain language (for example, create a landing page and publish it to HTML Pub). It generates the HTML and calls the create_page tool, then returns the live URL. Publishing a live page requires a paid plan; on the Free plan you can build and preview but not publish live.
Is the MCP connector free?
The MCP connector is included on every plan, including the free $0 plan (no credit card required), where you can build and preview up to 5 pages with the AI editor and MCP. Publishing a live, shareable URL requires a paid plan starting at $10/mo. There is no time-limited trial, and paid plans include a 14-day money-back guarantee.
How fast is publishing with the MCP connector?
Publishing returns a live, shareable URL in seconds — HTML Pub cites a roughly 60-second median to your first published page. There are no build tools or deploy pipeline; the assistant calls create_page and hands back the URL.
Can I use a custom domain with pages published via MCP?
Yes, on paid plans. Point a CNAME record to HTML Pub and SSL is handled automatically. Starter and Pro include 1 custom domain and Business includes 2; the Free plan does not include custom domains.
