Tool Name Strategy

Use -t, --tool-name-strategy to specify the tool name strategy, it will be used as the MCP server name (default: domain). This will be used as the MCP server name.

sitemcp https://vite.dev -t domain # indexOfVite / getDocumentOfVite
sitemcp https://react-tweet.vercel.app/ -t subdomain # indexOfReactTweet / getDocumentOfReactTweet
sitemcp https://ryoppippi.github.io/vite-plugin-favicons/ -t pathname # indexOfVitePluginFavicons / getDocumentOfVitePluginFavicons

Max Length of Content

Use -l, --max-length to specify the max length of content, default is 2000 characters. This is useful for sites with long content, such as blogs or documentation. The acceptable content length depends on the MCP client you are using, so please check the documentation of your MCP client for more details. Also welcome to open an issue if you have any questions.

sitemcp https://vite.dev -l 10000

Match specific pages

Use the -m, --match flag to specify the pages you want to fetch:

sitemcp https://vite.dev -m "/blog/**" -m "/guide/**"

The match pattern is tested against the pathname of target pages, powered by micromatch, you can check out all the supported matching features.

Content selector

We use mozilla/readability to extract readable content from the web page, but on some pages it might return irrelevant contents, in this case you can specify a CSS selector so we know where to find the readable content:

sitemcp https://vite.dev --content-selector ".content"

How to configure with MCP Client

You can execute server from your MCP client (e.g. Claude Desktop).

The below example configuration for Claude Desktop

{
  "mcpServers": {
    "daisy-ui": {
      "command": "npx",
      "args": [
        "-y",
        "sitemcp",
        "https://daisyui.com",
        "-m",
        "/components/**"
      ]
    }
  }
}

Tips

• Some site has a lot of pages. It is better to run sitemcp before registering the server to the MCP client. sitemcp caches the pages in ~/.cache/sitemcp by default. You can disable by --no-cache flag.
