Publish HTML Directly from Claude Desktop with MCP

The RunThis.page MCP server lets Claude Desktop publish HTML pages for you in a single step. Ask Claude to build a page, and it goes live instantly — no copy-pasting, no file downloads, no manual uploads.

MCP (Model Context Protocol) is an open standard that gives AI tools like Claude the ability to call external services. The RunThis.page MCP server exposes five tools that let Claude create, update, list, delete, and get analytics for your hosted HTML pages.

Step-by-step: Set up MCP for Claude Desktop

1. 1

   Get a Pro or Business plan

   The MCP server uses API keys, which require a Pro ($30/mo) or Business ($50/mo) plan. Sign up if you haven't already.

2. 2

   Generate an API key

   Go to Settings in your dashboard and create an API key. Copy it immediately — it's only shown once. It starts with rtp_.

3. 3

   Add the MCP server to Claude Desktop

   Open your Claude Desktop config file and add the RunThis.page server:

   macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   Windows: %APPDATA%\Claude\claude_desktop_config.json

   {
     "mcpServers": {
       "runthispage": {
         "command": "npx",
         "args": ["@runthispage/mcp-server"],
         "env": {
           "RUNTHISPAGE_API_KEY": "rtp_your_key_here"
         }
       }
     }
   }

4. 4

   Restart Claude Desktop

   Quit and reopen Claude Desktop. You should see the RunThis.page tools available in your conversation. The first run downloads the package automatically via npx.

What you can ask Claude to do

Once the MCP server is connected, Claude can use five tools to manage your pages:

• publish_page — "Build a landing page for my project and publish it" (pass a file path, inline HTML, or base64)
• update_page — "Update page a1b2c3d4e5 with a new hero section" (pass a file path, inline HTML, or base64)
• list_pages — "Show me all my published pages"
• delete_page — "Delete page a1b2c3d4e5"
• get_page_analytics — "How many views has my dashboard page gotten?"

Example prompts to try

Why MCP instead of manual upload?

• ✓ Zero friction — Claude builds and publishes in a single conversation. No file downloads, no browser tabs.
• ✓ Iterate fast — ask Claude to tweak the page and republish. The URL stays the same.
• ✓ Structured errors — if something goes wrong (plan limits, auth issues), Claude gets a machine-readable error with recovery instructions.
• ✓ No extra tools — npx downloads and runs the server automatically. Nothing to install globally.

The MCP server also works with ChatGPT, Claude.ai, Claude Code, Cursor, Windsurf, and VS Code with GitHub Copilot. If you prefer to publish programmatically from scripts or CI/CD, see the REST API guide.
