# Lyrenth MCP server
[](https://glama.ai/mcp/servers/lyrenth/lyrenth-mcp)
Read the web through [Lyrenth](https://lyrenth.com) 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`):
```json
{
"mcpServers": {
"lyrenth": {
"command": "npx",
"args": ["-y", "lyrenth-mcp"],
"env": { "LYRENTH_API_KEY": "aiwk_your_key_here" }
}
}
}
```
### Claude Code
```sh
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.
## Tools
| Tool | Arguments | Returns |
|------|-----------|---------|
| `read_url` | `url` (string, required), `fresh` (boolean, optional), `max_tokens` (integer, optional) | The page as a clean AIDocument: a short provenance header (token count + how much smaller than raw HTML) plus the Markdown body. `fresh: true` forces a fresh fetch instead of the cached copy; `max_tokens` caps the body to your context budget, trimmed at a clean paragraph or sentence boundary. |
| `read_urls` | `urls` (array of 1-20 strings, required), `fresh` (boolean, optional), `max_tokens` (integer, optional) | Up to 20 pages in one call, each as a clean AIDocument, with per-URL error isolation (a failed URL is reported and doesn't block the others). Billed one credit per successfully-read URL. |
| `check_usage` | none | Your plan tier, credits used against your monthly limit, credits remaining, and the reset date. |
## Configuration
| Env var | Required | Default | Notes |
|---------|----------|---------|-------|
| `LYRENTH_API_KEY` | yes | none | Free key at <https://lyrenth.com/signup> |
| `LYRENTH_API_URL` | no | `https://api.lyrenth.com` | Override for staging or self-host |
## 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.
## Local build
```sh
npm install
npm run build
LYRENTH_API_KEY=aiwk_... node dist/index.js # speaks MCP over stdio
```
