An MCP server that gives an AI assistant (Claude and other MCP clients) a publish tool. The assistant can publish text or HTML to Snapy.host and get back a shareable link.

Breaking change in 1.1.0: an API key is required

Versions before 1.1.0 no longer work. They publish without a credential, and the Snapy.host publish API no longer accepts that — for any file type.

Publishing anonymously was a contradiction in the product: the website has always made you verify an email address before your link goes live, while the API did not. It has been closed.

The key is free. Create one at snapy.host under API keys with a verified email address. There is no paid plan behind it — what a free account can publish is bounded by the one-live-link allowance, exactly as it is on the website.

Use it

Add this to your MCP client config (for example Claude Desktop), with your key:

{
  "mcpServers": {
    "snapy": {
      "command": "npx",
      "args": ["-y", "snapy-mcp"],
      "env": { "SNAPY_API_KEY": "your key here" }
    }
  }
}

Or run it directly from this folder:

npm install
node index.js

The tool calls the Snapy.host publish API at https://api.snapy.host. Set SNAPY_API to override the host, and SNAPY_API_KEY to supply your key (required).

Without a key the publish tool returns an error telling you to create one, rather than passing a bare 401 back to the assistant.

Tool

publish — args: content (required text/HTML), name (optional link name), filename (optional, default index.html). Returns the live link and a private analytics link.
