Lyrenth MCP server

Lyrenth MCP server

Read the web through Lyrenth's index from any MCP client.

Exposes three tools:

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.

• readurl turns a public web page into a clean AIDocument**: stable

• readurls** does the same for up to 20 URLs in one batch call.
• checkusage** 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.

Every tool declares all four MCP tool annotations (read-only, non-destructive, idempotent, and open or closed world) as explicit booleans, and the HTTP transport ships with a 14-test suite covering its security posture.

Hosted, no install

If your MCP client supports remote HTTP servers with a custom header (Claude and Cursor remote connectors do), there is nothing to run:

• URL: https://api.lyrenth.com/mcp
• Header: Authorization: Bearer aiwkyourkey_here

Same three tools, same key. The npx path below is for clients that speak MCP over stdio, and for anyone who prefers a local process.

Setup

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

Claude Desktop (one click)

Download lyrenth-mcp.mcpb from the latest release and open it. Claude Desktop installs the server and asks for your API key; there is no config file to edit. The bundle carries the same code as the npm package.

To build it yourself: ./scripts/build-mcpb.sh.

Claude Desktop / Cursor (manual config)

Add to your MCP config (Claude Desktop: claudedesktopconfig.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.
