Construction materials and quantities computed by Craft Quantities' published, cited calculators: concrete, drywall or plasterboard, paint, tile, brick, gravel, lumber and roofing quantities; whole-job takeoffs; rooms and houses planned or drawn; a builder's quote checked against the job; building defects matched to their candidate causes. Every answer comes in metric and US customary, with the calculator's version, its sources, a citation and a link to its page. Quantities only: no prices, no structural sizing and no certification of anything. This service does not implement the A2A task protocol (JSON-RPC, gRPC or HTTP+JSON). It answers over MCP (Streamable HTTP, no sign-in) at https://api.craftquantities.com/mcp and over a REST API at https://api.craftquantities.com/v1 described by https://api.craftquantities.com/openapi.json; the interfaces below name those two as custom bindings. It is stateless: it keeps no record of a request.

Find missing documents in a Kazakhstan / Middle Corridor trade-deal file before signature, shipment or committee review. 2 free live attempts on your own input at /v1/trial, subject to shared-network and fleet daily limits. Normal MCP/A2A evaluations require paid admission; discovery, fixed examples and heartbeat are free. Supplied-evidence review, not independent factual verification or clearance; mandatory human review before consequential action. Caller must invoke and enforce the result in its integration. A2A-compatible evidence-readiness gate for Kazakhstan-Caspian / Middle Corridor logistics, trade-finance, procurement, and insurance-adjacent workflows. Bring route, cargo, counterparties, and dated sources; get structured deal-risk triage, missing source categories, evidence gaps, watch-next indicators, decision-readiness score, risk signal, human-review routing, and named sanctions-exposure flags: OFAC named-sector (EO 14024/14114) and newly-formed-counterparty red flags, EU re-export / circumvention-watch jurisdictions (incl. the 20th-package measures on Kyrgyzstan), dual-use cargo screened against the EU/US Common High Priority List, a domestic-legal vs foreign-sanctions exposure decomposition, and a vessel deceptive-shipping-practice checklist. Deterministic rule-based logic, no model in the decision path. Presence-flagging and evidence triage only, not a sanctions determination. New to these gates? Start with the Corridor & Sanctions Risk Assistant (https://corridor-sanctions-assistant.agendamcp.dpdns.org) for plain-language orientation. Describe the route or counterparty and the next decision or review; fit, scope, fee, and timing are confirmed before work starts.
