Lyrenth MCP server

Read the web through Lyrenth from any MCP client.

Exposes three tools:

• read_url turns a public web page into a clean AIDocument: stable Markdown plus title, description, and structure, with the navigation and boilerplate stripped. Your agent reads cleaned, low-token content instead of raw HTML, and every result shows how many tokens it saved vs the raw page.
• read_urls does the same for up to 20 URLs in one batch call.
• check_usage reports your plan tier and credit usage.

Reads resolve through Lyrenth's cross-caller cache, and for verified domains they return the publisher's canonical version.

Setup

1. Get a free API key at https://lyrenth.com/signup (2,000 reads/month, no card).
2. Add the server to your MCP client.

Claude Desktop / Cursor

Add to your MCP config (Claude Desktop: claude_desktop_config.json):

{
  "mcpServers": {
    "lyrenth": {
      "command": "npx",
      "args": ["-y", "lyrenth-mcp"],
      "env": { "LYRENTH_API_KEY": "aiwk_your_key_here" }
    }
  }
}

Claude Code

claude mcp add lyrenth -e LYRENTH_API_KEY=aiwk_your_key_here -- npx -y lyrenth-mcp

Then ask your assistant to read a page, for example: "Read https://example.com/article and summarize it." It will call read_url and get the cleaned AIDocument back.

Why read through Lyrenth

• Cleaner, cheaper. One stable AIDocument shape per URL; far fewer tokens than raw HTML to a model.
• Cached across callers. The same URL fetched by many agents collapses to a minimal number of origin fetches, so it is fast and origin-friendly.
• Canonical when verified. When a site's owner has verified with Lyrenth, you get the version they authored, kept fresh by their change signal.
