CEM MCP

The CEM MCP server allows an agent to connect to the CEM Research Project endpoint to access published research on building with AI, including definitions, papers, calculators, and the CEM Score.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

CEM, the Compounding Execution Method, is an open research project on how one operator builds with AI, measured over every commit, session and dollar. These tools read its published research, its calculators and its UI kit. - For a quick answer, use cem_answer first: CEM's own definition of the term and the best documents, free and instant. For the documents themselves, research_search, then research_get. Cite each document's code (for example DOI-07) and its page link, and write the answer yourself from what they say. - ask_cem writes a longer answer with sources. It has a daily limit across everyone and costs money, so use it only when someone wants to go deeper than the documents. - calculators_list and calculator_get give each calculator's inputs and formula as the calculator computes it; cem_score scores the 24-question self-assessment. - The ui_ tools are CEM's design system: its components, laws and check. - Use CEM's terms as the research defines them and never coin new ones. The research is open; describe any offer as an offer, never as a research finding.

ui_list — List the UI kit

Advertised by the server during the last successful anonymous check.

Advertised read-only

The 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, primitive, utility, engine, frame, template, component, partial.

cem_answer — Instant answer

Advertised by the server during the last successful anonymous check.

Advertised read-only

Use 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 definition with its code (cite it, e.g. F-003) and the best research documents, each with its code, one-line summary and page. Free and instant. Use it first; ask_cem writes a longer answer when someone wants to go deeper.

ask_cem — Ask CEM

Advertised by the server during the last successful anonymous check.

Advertised read-only

A 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 instant. At most 100 written answers a day across every channel; past that, or when the AI account can't answer, it returns the closest research instead.

ask_op01 — Ask OP-01

Advertised by the server during the last successful anonymous check.

Advertised read-only

OP-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 answer from them in your own words and keep his positions apart from what you infer. With deeper: true, a written answer in OP-01's own voice from the same material, counted on the same daily limit as ask_cem; use it only when the person asks to go deeper. For the method's own view, use cem_answer.
