MCP tools · 22 exposed · ~2,910 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
audit_search ~175

Whether search engines can index the page and show it well (SEO), answer engines can lift a direct answer (AEO), and AI engines can reach it, read it without JavaScript, and name the entity (GEO): title, description, headings, alt, share card and its 1200×630 image, canonical, robots.txt for search and AI crawlers, sitemap, JSON-LD, question headings with short answers, server-rendered text.

Static by default; render=true adds the measured checks.

No output schema declared.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

install_skill ~106

They showed a site or a screenshot and want that feel. Measures its design language (colour roles, type, corners, shadows, density, hero shape, sections, motion) and returns the closest Lounge theme, pairing, family, and pieces per section, with what does not match.

countinteger––
namestringyes–

pick_direction ~200

Apply rules 3 to 5 of Pick a direction and the Recent picks check: calm words narrow to quiet, editorial, or sharp families; the history blocks recent directions, heroes, and effects; the group check blocks two-of-three matches; the name number breaks the tie.

Give a heading ("Look", "Write the idea", "Recent picks") to get only that section; outline=true lists the headings.
