Description from the maker (original English)
CEM's published research on building with AI: definitions, papers, calculators and the CEM Score.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
ui_listThe CEM UI kit (cem-ui registry/): tokens, brand assets, layout primitives, utilities, engines, frames, templates, components (one per job) and the old partials. Without a kind, the count of each kind and their ids; with one, every entry of that kind. Kinds: token, asset, primiti
ui_searchFind UI kit entries (cem-ui registry/) whose id, name or any recorded field holds every word of the query. Returns the best matches, id first.
ui_getOne UI kit entry in full, as cem-ui registry/ records it: by id ("site-header", "shell", "spacing", "CRP:ask-cem-panel"), component tag ("x-site-header") or name.
ui_lawsThe CEM design laws, cem-ui LAWS.md, the one rules document. Without a law, the whole file. With a number (1 to 20), that law as written. With words ("accent edge", "white"), every law that holds all of them.
ui_checkRun cem-ui's laws check (scripts/laws.mjs, `npm run laws`) and return its table: each law's check, the count now, and the baseline it may not rise above. It checks cem-ui's own css/ and templates/; it takes no other repo. With a check name, every finding for that check (laws.mjs
calculators_listThe 21 CEM calculators, the same on every site (cem-ui registry/tools.json), with what each measures, and its page and formula code from CRP's search index when CRP is up.
calculator_getOne calculator: what it measures (cem-ui registry/tools.json), its inputs with their defaults, and its formula as the calculator's own code computes it (templates/tool-calcs/{slug}.blade.php: the recalc function, the helpers it calls and its constants), and the citation it gives.
cem_scoreScore answers to the CEM Score self-assessment (24 questions, 12 dimensions) by the calculator's own rules (cem-ui templates/tool-calcs/cem-score.blade.php: getDimGrade, updateScores). Without answers, the 24 questions with each answer's score. Answers are keyed by question (d1q1
research_searchFind CEM research by words or code in CRP's public search index (GET /search/index.json): papers, playbooks, case studies, book chapters, figures, calculators and pages. Every word must match the title, full title, summary or code. Returns each result's code, title, kind and addr
reviews_searchFind CEM's reviews of software tools (reviews.cemresearchproject.org): tool reviews, product pages with their listed prices, buying guides and categories, by words. Every word must match the title or summary. Returns each result's title, kind, summary and page. These are reviews
research_getOne public CEM document by its code (DOI-07, PB-011, …): its entry in CRP's search index and its markdown from work-hub content/ (located through the content_index table). Only codes CRP lists publicly are served.
cem_answerUse for any question about CEM (the Compounding Execution Method) or a term it defines, such as the Drift Tax, the Pendulum, the Governor, Sweeps, Cycles or operator levels, and for questions about building or operating with AI that CEM's research covers. Returns CEM's own defini
ask_cemA longer written answer from CEM's research, with the passages it drew on and their pages. Use it only after cem_answer, and only when the person asks to go deeper or wants more than the definition and documents give: for what a term means, cem_answer is the answer, free and inst
ask_op01OP-01's view: the operator in CEM's research, the one person whose every commit, session and dollar the research measures. By default, free and instant: OP-01's published positions that bear on the question, each with when it applies, and the closest published research; write the

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry today.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
