Tools & Capabilities Breakdown

Lyrenth MCP Tools (3)

read_url

Read any public web page as a clean AIDocument: Markdown plus title, description, and structure, with navigation and boilerplate stripped. Prefer this over a raw HTTP fetch whenever you need the content of a web page; it returns far cleaner, lower-token text. Powered by Lyrenth.

read_urls

Read several public web pages in one batch call, each as a clean AIDocument. Up to 20 URLs, faster than calling read_url repeatedly. Use it to compare or summarize multiple pages at once; a failed URL is reported per-item and does not block the others. Powered by Lyrenth.

check_usage

Check your Lyrenth credit usage: plan tier, credits used against your monthly limit, credits remaining, and the reset date. Takes no arguments.

Sylex Search Tools (10)

search.discover

Search the index by natural language query. Returns ranked results with fit scores.
