Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Check claims against current public CMBS filings and NPORT-P coupons, with citations.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
quickstartCompact capability manifest for clients: purpose, workflow, routing table, examples, vocabulary guard, scope caveats, next actions, and contact. A short, low-token summary of what this server does and what it returns.
coverageWhat this server covers: deals and loans against the universe, the field inventory with full bound definitions, counterparty roles, current-only scope, and dual-sourced agreement stats (single-source reported separately). An OUT_OF_COVERAGE answer means the deal or field is outsi
find_dealsSearch covered deals by id, trust name, CIK, alias, shelf, vintage or deal_ref. An EXACT query returns one dominant result. A fuzzy query returns a small ranked set with match reasons, periods and a suggested next call. Returns at most the requested number of matches.
covered_dealsList every deal this server can verify, with CIKs, aliases and filing periods. Returns the full covered set, which can be long.
verify_loan_fieldVerify one loan-grain field of a CMBS loan against the SEC 10-D and ABS-EE filings. Values are TRUST-LEVEL (this trust's piece, not the whole loan). Always the CURRENT period; the receipt stamps its as-of. Pass claimed_value: you get CONFIRM / DENY / CONFLICT / UNVERIFIED plus an
verify_deal_fieldVerify one pool-level field of a deal: the ABS-EE loan-tape rollup against the 10-D trustee's reported fact. These are COLLATERAL (loan-pool) balances and flows, NOT bond or certificate balances, and SCHEDULED and ACTUAL are different fields. No loan_id. Always the CURRENT period
verify_fund_holding_couponVerify the NPORT cross-filer annualized coupon rate (annualized_rate) for one security identifier. Security-grain, N-source receipt: citations are peer NPORT-P filings by registrant CIK, dissenters included. CURRENT-ONLY (latest NPORT period exported). Ticker matches are not uniq
verify_building_sizeVerify issuance building size (Annex A vs ABS-EE). Units matter: mismatched units return receipt status UNITS_INCOMMENSURATE, not CONFLICT/DENY. A deal or loan outside coverage returns OUT_OF_COVERAGE.
verify_appraised_valueVerify issuance appraised value (Annex A vs ABS-EE). Date/basis mismatches return DATE_INCOMMENSURATE or BASIS_INCOMMENSURATE, not CONFLICT/DENY. A deal or loan outside coverage returns OUT_OF_COVERAGE.
verify_counterpartyAdjudicate 'who is the on deal X' against the SEC 10-D counterparty roster (today: master and special servicer). A SINGLE-SOURCE roster fact. Master is the roster party, NOT the ABS-EE tape's primary servicer. Pass claimed_name: CONFIRM/DENY under the ledger's name normalization,
verify_loan_status_countsVerify count claims over loan status ('N in special servicing / paid off / defeased') for a deal. Counts are DERIVED from the ABS-EE tape, not reported by any filing. Three grains, never mixed: activity (active, resolved_paid_off, defeased); servicing: in_special_servicing = loan
verify_claimsBulk verifier: paste text, get per-claim statuses. ASSERTIONS ONLY: a QUESTION ('is it $9.4M?') binds nothing and returns total 0; single-value questions are not claims and are not checked here. Deterministic grammar, four families: loan fields, pool fields, servicer identity, lo

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 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 4 days ago.

Claim in, receipt out. Receipts checks claims in commentary, articles, and AI-generated passages against current public CMBS filings and NPORT-P coupons, and returns each answer with filing citations and a list of the spans it could not check.

Receipts covers public CMBS and NPORT-P coupons to start, with more coming soon. Coverage is current-only and limited to what coverage reports. Anything outside it comes back as unverified, never as a judgment about the claim. For deeper coverage or historical data, write to cairn@cmdrvl.com.
