Whose server it is
  • Registry nameapp.htmldrop/mcpverified in the MCP registry

The registry name sits under htmldrop.app. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Once connected

  • For "publish a single HTML file to a shareable link", the likely first call is htmldrop_publish.
  • For "host a portfolio made with ChatGPT or Claude", the likely first call is htmldrop_publish.
  • htmldrop_publish, htmldrop_delete change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

  • Tools that change data, on a server that answers without a sign-in: htmldrop_publish, htmldrop_delete

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • htmldrop_publish

    Publish an HTML or Markdown document as a hosted page on htmldrop. Returns the public share URL. Use this whenever a user asks to publish, share, or 'put on the web' some HTML / Markdown content. Pass exactly one of `html` or `markdown`.

  • htmldrop_list

    List every site the authenticated tenant has published. Returns each site's slug, id, and public URL.

  • htmldrop_delete

    Delete a site by its id. The id is the opaque string returned from htmldrop_list (NOT the slug). Once deleted the public URL returns 404 immediately.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "htmldrop": {
      "type": "http",
      "url": "https://htmldrop.app/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http htmldrop https://htmldrop.app/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://htmldrop.app/mcp as a custom connector in the settings.

Also shipped through: npm

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
