## 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 2026-10-23.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 67/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1182 tokens (~147/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 94% 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (8)

### `list_supported_formats` (~26 tokens)

Supported e-invoice formats

Which formats, profiles and rule sets this service supports, and what each tool costs.

### `detect_invoice` (~112 tokens)

Detect e-invoice format

Identify the format, syntax, profile/customization and country standard of an e-invoice file. Cheap first step before validating.

Input parameters:

- `content` (string): Invoice XML (UBL, CII, XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, KSeF FA(3)) as text
- `content_base64` (string): A ZUGFeRD / Factur-X PDF (or any invoice file) as base64, when the invoice is not plain XML

### `parse_invoice` (~119 tokens)

Parse e-invoice to JSON

Extract the invoice as normalised JSON: number, dates, seller, buyer, lines, VAT breakdown, totals, payment details. Works for every supported format.

Input parameters:

- `content` (string): Invoice XML (UBL, CII, XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, KSeF FA(3)) as text
- `content_base64` (string): A ZUGFeRD / Factur-X PDF (or any invoice file) as base64, when the invoice is not plain XML

### `fix_invoice` (~259 tokens)

Auto-fix e-invoice

Fix validation errors of an EN 16931 invoice (XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, UBL, CII) deterministically: empty elements, decimals, date and code formats, specification ids; with totals=true also recalculates totals and the VAT breakdown from the lines. Data that is not in the file (Leitweg-ID, seller contact, endpoint ids, payment terms) is taken from "values"; missing ones are listed in needs_input. Returns the change list, the remaining errors and the corrected XML. Counts as 2 requests.

Input parameters:

- `content` (string): Invoice XML (UBL, CII, XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, KSeF FA(3)) as text
- `content_base64` (string): A ZUGFeRD / Factur-X PDF (or any invoice file) as base64, when the invoice is not plain XML
- `dry_run` (boolean): Only report what would change
- `totals` (boolean): Allow recalculating document totals and VAT breakdown from the line amounts
- `values` (object): Values for data that is missing in the file

### `validate_invoice` (~226 tokens)

Validate e-invoice

Run the official rule set for the detected format (KoSIT for XRechnung/ZUGFeRD/Factur-X, OpenPeppol for Peppol BIS, FA(3) schema for KSeF, Porezna uprava HR-CIUS schematron for Croatian eRačun, Facturae XSD + calculation/NIF/DIR3 rules for Spain, LHDN SDK rules for MyInvois). Returns valid/invalid with every failed rule: id, severity, message, XPath.

Input parameters:

- `content` (string): Invoice XML (UBL, CII, XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, KSeF FA(3)) as text
- `content_base64` (string): A ZUGFeRD / Factur-X PDF (or any invoice file) as base64, when the invoice is not plain XML
- `kosit` (boolean): Run the full KoSIT schematron (default true). false = schema and core checks only, faster

### `render_invoice_html` (~121 tokens)

Human-readable invoice document (HTML, A4 print layout) from the XML, in the requested language.

Input parameters:

- `content` (string): Invoice XML (UBL, CII, XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, KSeF FA(3)) as text
