Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Dutch construction facts with measured accuracy + NL coordination. Never holds third-party funds.
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 7, 2026. The maker wrote them, not us; we show them as plain text.
ask_astranlTurn a real-world task or question into a routing decision: whether AstraNL can help, which one tool to call, what to supply, what can and cannot be verified. No commitment, nothing created, no key. Also answers whether a physical task is feasible in the Netherlands.
check_counterparty_nlCheck a Dutch or EU counterparty against official sources before your own next step, such as onboarding a supplier, paying an invoice or signing an order. Give the KvK number, the company name and the EU VAT number as your document states them. Returns verdicts, not register data
record_counterparty_checkMake a result of check_counterparty_nl verifiable by others: records its digest in the AstraNL signed public log and returns a reference that a colleague, approver or auditor can check later with verify_astranl, without trusting AstraNL. Works only for a check AstraNL produced in
create_taskAsk AstraNL to find and coordinate a verified executor for a physical task in the Netherlands. Returns an ingress receipt at once and a case once planning found a path; the client pays the executor directly; AstraNL holds no money. Fee: submitting costs nothing; AstraNL charges 1
check_taskCurrent state of a task or ingress receipt from create_task, and who must act next. Returns only what is recorded; infers nothing.
get_evidenceMachine-checkable evidence for an AstraNL task, action or receipt: the signed log events that mention it, each verified live, with a proof block stating what is verified, what is not, validity, status, limitations and next actions.
verify_astranlVerify any AstraNL reference without a key. Returns two separate layers: integrity (payload hash, Ed25519 signature, Merkle inclusion, recomputed live) and claim (what exactly is attested, by whom, from which source, when, under which method, with which validity limits and curren
ground_astranlGet compact, source-linked real-world context for an LLM in ONE read-only call. Searches AstraNL public materials or tender records, or its protocol identity. Use source=public_tenders for tenders, materials for products; auto keeps domains separate. Returns record update times,
ground_componentGround a machine, robot or industrial automation component in live market reality with ONE call. Give a manufacturer part number and optionally the maker. AstraNL queries its verified distributor connections (Nexar/Octopart, Mouser, element14/Farnell NL, OEMsecrets) in parallel,
ground_citationCheck one scientific reference before you reuse or cite it, with ONE call. Give a DOI. AstraNL reads the Crossref work record and every Crossref notice that updates it, the OpenAlex retraction flag and the Europe PMC publication types and retraction, erratum and concern links, an
construction_summaryOne-call overview of Dutch construction facts: permit publications last 90 days (national), lead-time status, number of open public works tenders, latest CBS periods, construction laws taking effect in the next 365 days. Permit kind accuracy is measured, not assumed: manual valid
construction_permitsOfficial permit publications counted per issuing body (municipality, province, water board) and kind (application, granted, refused, ...) over the last N days (default 90, max 400). Permit kind accuracy is measured, not assumed: manual validation gate B on a 200-row sample (2026-
construction_leadtimesPermit lead times (application to decision, median and quartiles) from official pairs. Currently CLOSED: the answer says CLOSED with the reason until validation gate C passes; no lead time is estimated before that. Permit aggregates only: no permit rows, publication identifiers,
construction_tendersOpen Dutch public works tenders from TenderNed (announcements with a future closing date): buyer, CPV, procedure, published and closing date, days left, European flag, TenderNed id and link. Tender names are not returned; open the link for the full notice. Read-only. Every answer
construction_lawsConstruction law calendar: dated rules in force or planned (Omgevingswet, Wkb, EPBD IV, MPG, CPR, ...), each with its own official or sector source and last-verified date; rows whose planned date passed are flagged needs_reverify. Read-only. Every answer carries source provenance
construction_economyCBS construction economy: build cost input price index, construction bankruptcies, construction vacancy rate (latest stored period, CBS status Voorlopig/Definitief per row, freshness) plus CBS indicators (dwelling permits, establishments, labour). Provisional figures are revised
construction_zonesDutch zero-emission and low-emission zones from NDW as published: municipality, zone label, status, start, vehicle categories, transition rules, bbox centre; derived_ze_logistics is derived by AstraNL. Source recount (ids and hashes) is reported. Read-only. Every answer carries s
construction_naturaNatura 2000 sites in the Netherlands from RVO / PDOK: number, site label, protection type, status, site code, bounding box (lon/lat). Filter with site. Source recount is reported. Read-only. Every answer carries source provenance (source, source_url, licence, as_of, retrieved_at
construction_eventsCloudEvents 1.0 feed of construction signals, oldest first after since_id: daily permit aggregate cells (with gate B accuracy), newly published works tenders (AAO), laws coming up. Continue with next_since_id. Permit aggregates only: no permit rows, publication identifiers, title
nl_municipal_build_rulesDutch municipal rules for a renovation or building job, with ONE read-only call. Give a municipality, optionally the planned bouwkosten excluding VAT. Returns the 2026 omgevingsvergunning fee, leges, for the technical building activity as the municipality's own regulation sets it
check_materialCheck one building material in live Dutch store reality with ONE read-only call. Exact identity only: a GTIN with valid check digit, a store variant or the exact partner feed link; plain words return candidates you can check exactly next. Returns every offer of the same trade ite
check_estimate_materialsCheck every material line of an AstraNL estimate case you hold the token of (from estimate_case_create) against the current offer of the same product: PRICE_UP or PRICE_DOWN beyond 5 percent, UNAVAILABLE, NOT_FOUND_IN_CHECKED_SOURCES, CHEAPER_SAME_GTIN at another store, each with
order_materialsTurn an AstraNL estimate into draft purchase lists for a project, one list per store and wave, and hand them to the project administrator. Needs the project agent key (agk_...) as X-Agent-Key on the connection; the estimate tools use the connection key, so use a separate connecti
estimate_case_createCreate a real estimate case through the public router. Reuses the connection X-Agent-Key (get one free with POST https://astranl.com/api/agents/register; the api_key is shown once; send it as the X-Agent-Key header of the MCP connection); requester_kind is agent. Save case_id and
estimate_case_statusRead the exact public case-status JSON using case_id and its token. Human-client questions and documents retain their language. Deliver an estimate only when release_state is RELEASED; DONE alone is insufficient.
estimate_case_answerSubmit human answers as a map from question ID to text. The public router validates, merges and queues an operator rerun; submission does not itself spawn processing. Requires the case token.
estimate_case_filesUpload photos or plans as base64 contents, never local paths or URLs. Requires the case token. Public feature flag, type checks, sanitization and quotas apply: 10 files, 15 MiB each, 60 MiB per case. Upload acceptance does not prove incorporation into an existing estimate.
estimate_case_videoVideo action=create takes one base64 file up to 250 MiB and reuses the connection agent key (X-Agent-Key header of the MCP connection; get one free with POST https://astranl.com/api/agents/register). action=status takes intake_id and its token only. After case creation, use case_
market_indicatorsRead market indicators with latest values, source dates, expected_in_5_days and measured backtest error where available. Optionally select one exact indicator key. Missing snapshots return unavailable; absent values are never invented. Forecasts are not guarantees.
commitment_attestIssue a certificate recording the fact of an agreement only. AstraNL holds no money, guarantees no performance and is not a party. Submit only an agreement the parties have actually made and authorized you to record. The connector sets created_by; it is not a caller field. The JS
commitment_verifyVerify an agreement certificate by ID, up to 40 characters. Returns the verification service verdict unchanged. A genuine certificate does not guarantee performance.
housing_needRegister a real person's housing need. A real person must have asked for this submission and agreed to it and to sharing the necessary personal data with AstraNL. Never use this tool for test or synthetic data. Include only necessary information about the housing problem and the
machines_searchFind machines and robots suggested for a task. Read-only search: does not claim, reserve, acquire, buy or pay for anything. Results describe the registry suggestions, not guaranteed availability.
estimate_costInstant planning cost figure in EUR for one job category in the Netherlands (not a quote; answers in under 2 s). labor_cost = labor_hours x labor_rate x location_mult, always. The rate comes from AstraNL's S_PRICEBASE (CAO wage with employer cost, overhead and profit) or its labo
searchSearch AstraNL coordination data (robots registry, service categories, and merchant parts by keyword). Returns a list of results, each with an id and a short title/snippet, for use with the fetch tool. Read-only. This is the generic discovery entry point expected by agent framewo
fetchFetch the full record for a single result id returned by search (robot passport, category detail, or merchant SKU). Read-only. Id exchange:board returns the AstraNL exchange: verified supply and demand records with landed cost, 1 percent fee after confirmed delivery, terms sealed
