Onto MCP

Onto MCP provides tools for AI agents to retrieve clean Markdown from websites and evaluate their AI-readability. It exposes functions to read URLs, score content quality, batch process sites, map sitemaps, and extract structured data, reducing token usage and hallucinations by serving pre-cleaned content.
