- Version: `1.1.0`

## 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**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 77/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 5678 tokens (~246/item across 23 items; 19 tools + 4 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 80/100
  - Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 99/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 95% of tool parameters carry a description.
  - Structured output schemas are declared (95% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 19 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 21 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).
  - Supports UI / widget rendering.

Use it when the user asks for a receipt or proof of a check. Always ask the user first: 'Normal or detailed receipt?', then call it. Use the proof code from verify_company. Don't use it to run a new check: call verify_company.
Inputs: proof_code (e.g. 'FUE-FR-20261015-DZ7TP9', any case; a lookup's meta.receipt.request_id also works, same key), format 'normal' or 'detailed'.
Returns: data.markdown, the branded receipt: show it as is; data.text, plain text.
Limits: free; 30 a minute. The key that ran the check also sees its reference; anyone else, the public view. Read-only.

### `review_report` (~233 tokens)

A review-ready report on a company

Produce one review-ready report on a company: identity and links with reasons, facts with sources, last year's changes and gaps, and every check at once (insolvency, sanctions, address, VAT, and in France the public contracts won).
Use it for the registry part of a KYB or supplier review you must file (not full KYB: no UBO, PEP or adverse-media checks). Don't use it for one quick fact: call lookup_company.
Inputs: country and identifier, as lookup_company (e.g. 'FR', '441639465').
Returns: company, facts, links, decisions, changes_last_year, modules, gaps, uncertainty, sha256, markdown.
Limits: 8 units; API key required. Read-only.

Input parameters:

- `country` (string, required): ISO country code: FR or ES or GB.
- `identifier` (string, required): Official ID, as lookup_company: FR SIREN (9 digits), SIRET or VAT; ES Registro Mercantil sheet, e.g. VI-23266. GB: Companies House company number, e.g. 00445790.

Output parameters:

- `data` (object)
- `meta` (object)

### `check_supplier_list` (~238 tokens)

Check a supplier list (registry check)

Check a supplier list against the official registers: which suppliers are ok, which need a look and why (e.g. in liquidation since a date, per BODACC), with a proof code each, and a private report link to share.
Use it for 2 to 100 suppliers at once, or to read a batch you started. Don't use it for one company: call verify_company.
Inputs: rows [{reference, company_name, country, identifier}] (an official ID is best; a name alone counts only with postal_code and street matching one company), or batch_id.
Returns: counts by review_state (ok, review, could_not_confirm, not_covered, error), the review rows with reasons, share_url; 'next' when still checking.
Limits: 5 units a row (+2 for a name), checks reused 24 h free. A registry check, not KYB or sanctions clearance; no person's name.

Input parameters:

- `batch_id`: A batch this key started, e.g. sb_3Kq9…
- `rows`: Up to 100 suppliers. Leave out to read a batch_id.

### `list_coverage` (~175 tokens)

List covered countries and ID formats

List the countries, ID formats and official sources Fuentio covers. Free, no key.
Use it first when unsure whether a country or ID format is supported, or to explain coverage. Don't use it to check a company: call lookup_company or search_companies.
Inputs: none. Example: list_coverage().
Returns: per country, status (available or planned), coverage level, ID formats with real examples and whether lookup works, regional registers, and sources with licence and update frequency.
Limits: 0 units. Read-only. Covered today: France, Spain and United Kingdom.
Search words: company registry, KYB, SIREN, RCS, Annuaire des Entreprises, société; BORME, Registro Mercantil, empresa, sociedad; Companies House, company number, Ltd, plc, LLP.

Output parameters:

- `data` (array)
- `meta`
