Category Maps and Location
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability61
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 6570 tokens (~182/item across 36 items; 36 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage85
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 56% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 36 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 37 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
ask_astranl ~83
Turn 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.
| Name | Type | Req | Description |
|---|---|---|---|
| question | string | yes | your task or question in plain words, any language |
No output schema declared.
No examples provided.
check_counterparty_nl ~325
Check 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: whether the KvK number has an active registration, whether the name matches a registered name, whether the VAT number is valid in VIES and whether its VIES name matches the register, EU sanctions list candidates, whether an insolvency case is published under the KvK number in the Dutch insolvency register, open questions and a check_id. Read-only, no key, no cost. AstraNL does not search the Dutch register by name; look a number up at kvk.nl. When a colleague or auditor must verify it later, call record_counterparty_check with the check_id. It does not prove who may sign for the company, who owns a bank account, solvency or reliability.
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | – | not used; kept for compatibility, AstraNL does not search the register by name |
| company_name | string | – | the company name exactly as your document or contact states it |

check_estimate_materials ~123
Check 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 source and read time, plus the open findings of the daily monitor for that case. Read-only; an estimate is re-read live at most once in 6 hours.

estimate_cost ~286
Instant 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 labour cost canon; hours from CBS-derived norms where AstraNL has one, otherwise a planning factor labelled ASSUMPTION; location_mult is 1.0 with its basis (no sourced regional factor for renovation labour). Each material line says price_source live_read (store, read_at, product link) or indicative (basis and date). No robot price or savings is given without evidence. Sources are in estimate.labour and estimate.materials. For a reviewed estimate of a real job use estimate_case_create, then estimate_case_status and estimate_case_answer; estimate_case_files for photos or plans and estimate_case_video for video intake. Read-only, free.
| Name | Type | Req | Description |
|---|---|---|---|
| area_m2 | number | – | Surface area or working volume in square meters. Optional but improves accuracy. For non-area tasks (e.g. plumbing repair) pass 0 or omit. |
| category | string | yes | Service category. Same enum as create_task. |
| location | string | – | City in the Netherlands. Pricing varies by region (Amsterdam tends to be highest). Optional — omitting uses national median. |
No output schema declared.
No examples provided.
fetch ~100
Fetch 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 before execution, and how to post.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Result id from search (e.g. robot:DJI-Matrice, sku:16759:Green-flor). |

| Name | Type | Req | Description |
|---|---|---|---|
| task_id | string | yes | task id, action id or receipt id |
No output schema declared.
No examples provided.
ground_astranl ~335
Get 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, fresh/stale/unknown labels, record disagreements, coverage gaps and ready-to-use context_text. Never books, contacts or pays anyone. Not a general web search: no match is not proof of absence; a cached price is not a quote. Optional astranl.reality-link.v2 profile checks exact source-record claims. It does not promote registry records to independently verified real-world facts. official.deadline on tender:TED-* records is checked live at the EU publisher (TED), budgeted and cached; unavailable means UNKNOWN.
| Name | Type | Req | Description |
|---|---|---|---|
| budget_ms | integer | – | – |
| claims | array | – | v2 only. Each claim names a record id from a previous result, a predicate and the expected value. |
| max_age_seconds | integer | – | – |
| max_items | integer | – | v1 only; v2 looks up at most 12 records and refuses max_items. |
| protocol | string | – | Omit for the v1 context call. Set to astranl.reality-link.v2 together with claims to check typed claims against source records. |
| query | string | yes | Short subject, product keywords or identifier; all product keyword groups must match. |
| source | string | – | v1: auto, materials, public_tenders, protocol_identity or all. v2 requires an explicit materials, public_tenders or protocol_identity. |
No output schema declared.
No examples provided.
ground_citation ~442
Check 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, and returns a status: RETRACTION_NOTICE_FOUND, EXPRESSION_OF_CONCERN_FOUND, CORRECTION_NOTICE_FOUND, NO_NOTICE_IN_CHECKED_SOURCES or NOT_FOUND_IN_CHECKED_SOURCES, with each notice DOI, type and date, the source URLs and the observation time. Every fresh answer carries a SHA-256 digest sealed with the AstraNL moment seal and an AstraLock event id you can check later with verify_astranl. Limits: registry data at the observed time, never a judgement of the science; NO_NOTICE_IN_CHECKED_SOURCES means only these three registries; answers are cached for 24 hours. Never contacts authors or publishers. Writes (why the tool is not read-only): each fresh answer, not one served from the 24 hour cache, appends one event to the public AstraLock log with the DOI, the digest and the status, so the answer can be verified later, and stores the answer in an AstraNL database table (citation_groundings) that serves the cache and counts the budget; the row names only the door (mcp), nothing about the caller. Live budget: 300 fresh reads a day across all MCP callers; after that only cached answers, status DAILY_LIVE_BUDGET_SPENT. Logging: every MCP call is journaled with the tool name, outcome, argument length, caller class (external, probe, crawler, self), a SHA-256 hash of the caller network /24 and the client family; for demand statistics also the first 160 characters of a query, question, title or id argument and the user-agent; never the address itself, other arguments or an account.

ground_component ~529
Ground 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, keeps only offers whose part number matches exactly after normalisation, screens maker and sellers against the EU consolidated sanctions list and the US Consolidated Screening List, and returns availability, stock seen, authorized sellers, lowest unit price seen in EUR, lifecycle values and per-source status. When AstraNL holds the manufacturer own lifecycle or discontinuation page for the part, the answer also carries manufacturer_lifecycle: status, date, the successor the manufacturer names and the page SHA-256, kept separate from seller-reported values; asking for a successor also shows which discontinued part it replaces. Every fresh answer carries a SHA-256 digest sealed with the AstraNL moment seal and an AstraLock event id you can check later with verify_astranl. Limits: distributor data is seller-reported at the observed time, not a quote and not a delivery promise; NOT_FOUND_IN_CHECKED_SOURCES means only these sources; answers are cached for 24 hours. Never orders, contacts or pays anyone. Writes (why the tool is not read-only): each fresh answer, not one served from the 24 hour cache, appends one event to the public AstraLock log with the part number, the maker, the digest, the availability and the number of exact offers, so the answer can be verified later, and stores the answer in an AstraNL database table (component_groundings) that serves the cache and counts the budget; the row names only the door (mcp), nothing about the caller. Live budget: 40 fresh reads a day across all MCP callers; after that only cached answers, status DAILY_LIVE_BUDGET_SPENT. Logging: every MCP call is journaled with the tool name, outcome, argument length, caller class (external, probe, crawler, self)…
| Name | Type | Req | Description |
|---|---|---|---|
| manufacturer | string | – | optional maker name, e.g. Allen-Bradley; offers from other makers are then dropped |
| mpn | string | yes | manufacturer part number, exactly as printed by the maker, e.g. 1756-L85E |

housing_need ~135
Register 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 person to contact. Contacts are separated from free text and kept only for this case, without enrichment. Returns a durable receipt, not a promise of processing or resolution. Set real_person and consent to true only when both statements are true.
| Name | Type | Req | Description |

| consent | boolean | yes | – |
| need | string | yes | – |
| principal | string | yes | – |

market_indicators ~64
Read 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.

nl_municipal_build_rules ~214
Dutch 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, and whether a skip or container on the public road needs a permit, a notification or nothing, with the permit fee and precario where confirmed. Every answer names the regulation, article and source URL, the read date and how it was verified. Coverage: all 342 municipalities for leges, 296 for containers. Limits: the municipality decides; spatial or other permit parts are not added; a fee is withheld when the tariff is not verified. Free, no auth, no side effects.
| Name | Type | Req | Description |
|---|---|---|---|
| bouwkosten_eur | number | – | planned construction cost excluding VAT in euro; default 50000 |
| municipality | string | yes | Dutch municipality name or CBS code, e.g. Zaanstad or GM0479 |

order_materials ~469
Turn 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 connection. Read-only actions: me, case, estimate_links, list, order_status (reads an existing order record, it never places one). Actions that write: import_estimate (creates draft lists) and finish_list (sends one draft for approval). Required fields by action: me: none; case: project_id; import_estimate: project_id, estimate_case_id, estimate_token, idempotency_key; estimate_links: project_id; list: project_id, list_id; finish_list: project_id, list_id, list_revision, version, idempotency_key; order_status: project_id, order_id. Typical order: import_estimate, then list for each list_id, then finish_list with the revision and version read. The estimate must be RELEASED after review and must carry a material order plan, otherwise import_estimate answers a failure and writes nothing. If a write answers outcome_unknown, repeat the same call with the SAME idempotency_key; never use a new key. A project administrator approves the exact list. Nothing is ordered, approved or paid by this tool. A 202 means accepted for work, not completed.
| Name | Type | Req | Description |
|---|---|---|---|
| action | string | yes | what to do; see the tool description for the fields each action takes |
| estimate_case_id | string | – | the estimate case id, ESTREQ-YYYYMMDD-xxxxxxxx |
| estimate_token | string | – | the token of that estimate case, from estimate_case_create |
| idempotency_key | string | – | 8 to 80 letters, digits, - or _; the same key replays the same answer |
| list_id | string | – | a purchase list id, PL-... |
| list_revision | integer | – | the revision of the list as read |
| order_id | string | – | an order intent id, PI-... |
| project_id | string | – | the project case id, PRJ-... |
| version | integer | – | the current_version of the list as read |

record_counterparty_check ~125
Make 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 the last 48 hours. The public record holds no name, number or address of the checked party. Calling it again returns the same reference.
| Name | Type | Req | Description |
|---|---|---|---|
| check_id | string | yes | the check_id returned by check_counterparty_nl, ASTRA-K- and 16 characters |
No output schema declared.
No examples provided.
search ~75
Search 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 frameworks.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Free-text search query. |

verify_astranl ~180
Verify 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 current status VALID/EXPIRED/REVOKED/UNKNOWN). Integrity never implies the claim is true for your purpose; you apply your own acceptance rules. Tells you when to re-verify and how to consume a VALID receipt for a next action. Read-only, deterministic, no model in the path.
| Name | Type | Req | Description |
|---|---|---|---|
| ref | string | yes | Any AstraNL reference: action receipt ASTRA-A-..., policy receipt ASTRA-R-..., consumption ASTRA-C-..., log event alk_..., attestation att_/atr_..., ingress receipt RCPT-n |
