operstack

MCP server that lets Claude, Cursor and any MCP client measure a site the way a search engine and an AI read it: AI visibility score, llms.txt health, the sixteen content gates, and a full public-signal audit. Free data only, no account, nothing stored.

Scores whether ChatGPT and other AI assistants can read, understand and quote a public website. Free tools need no account: audit_site scores a site out of 100, compare_sites puts up to four sites side by side, check_llms_txt checks the llms.txt map. OperStack Watch subscribers who add their key also get their weekly report. Setup: https://oper-stack.com/mcp/
