## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 986 tokens (~328/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (3)

### `check_counterparty_nl` (~325 tokens)

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.

Input parameters:

- `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
- `kvk_number` (string): Dutch KvK number, 8 digits, as printed on the invoice, quote or website
- `purpose` (string): optional: the next action you are about to take, for example approve supplier or pay invoice
- `vat_number` (string): EU VAT number with country prefix, for example NL810433941B01

### `record_counterparty_check` (~125 tokens)

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.

Input parameters:

- `check_id` (string, required): the check_id returned by check_counterparty_nl, ASTRA-K- and 16 characters

### `verify_astranl` (~180 tokens)

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.

Input parameters:

- `ref` (string, required): Any AstraNL reference: action receipt ASTRA-A-..., policy receipt ASTRA-R-..., consumption ASTRA-C-..., log event alk_..., attestation att_/atr_..., ingress receipt RCPT-n

### Is the AstraNL Dutch counterparty check MCP server safe to use?

AstraNL Dutch counterparty check scores 83 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the AstraNL Dutch counterparty check MCP server expose?

AstraNL Dutch counterparty check exposes 3 tools: check_counterparty_nl, record_counterparty_check, verify_astranl. Their descriptions and schemas cost roughly 630 tokens of context every time the server is loaded.

### Does the AstraNL Dutch counterparty check MCP server require authentication?

No. We connected to AstraNL Dutch counterparty check without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the AstraNL Dutch counterparty check MCP server still maintained?

AstraNL Dutch counterparty check is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the AstraNL Dutch counterparty check MCP server?

VerifyMCP ran 13 checks on AstraNL Dutch counterparty check, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
