Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
list_decision_briefsList the CULT+MATH Decision Briefs: who each is written for, its headline finding, price, page and payment link. Also lists bundles and the custom brief.
get_decision_briefEverything public about one brief: the six decisions it covers with the evidence line for each, pages, edition, price, sample pages, free answers, guarantee, license and payment link. The PDF itself is delivered only after payment.
search_cultmathSearch the free CULT+MATH studies and answers (and the briefs) by keywords. Returns titles, URLs, dates, the lead finding and the brief that goes deeper.
list_decisionsThe 54 decisions inside the briefs (six per brief), each with who owns it, who contests it, and the public evidence line. Use an id with buy_decision_evidence to buy the full evidence for just that decision.
buy_decision_evidenceStarts a Stripe checkout for the full evidence behind one decision: sourced and dated figures, what would flip the answer, and the brief's stated limits. Returns a checkout URL for the user to approve and pay, and a session_id. After the user pays, call get_decision_evidence with
get_decision_evidenceReturns the full evidence for one decision once it is paid for. Pass the session_id from buy_decision_evidence, or the Checkout Session id of a full brief, team license, pack or all-access purchase that includes this decision.
get_documentEvery published finding (question and answer) of one CULT+MATH study or answer page, with its date, license, citation line and related brief.
run_filing_trendA fresh, citable measurement: what share of U.S. 10-K filers mention a phrase, year by year, from SEC EDGAR full-text search. Every run carries two controls ("competition" as the filer denominator; "shrinkflation", which must be 0) and its stated limits, plus a run id and a dated

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 (1.1.0) reached the registry today.
