## 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 2026-08-03.

- **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 4 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**: 79/100
  - 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 1113 tokens (~185/item across 6 items; 4 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `search_italian_tax_sources` (~264 tokens)

Search TaxCompass's primary-source corpus and return passages to cite.

    Hybrid semantic + keyword retrieval over Italian tax & company-law primary
    sources: Normattiva (statute), Agenzia delle Entrate (circolari & guidance),
    INPS (social security), pinned tax-year tables (IRPEF brackets, INPS rates,
    forfettario thresholds & coefficienti di redditività), the ATECO 2025 code
    catalogue, and EU/treaty sources.

    Each result carries a `chunk_id`, `source`, and (usually) a `url`. Cite the
    `url` and quote the `text`; do not assert Italian tax facts the passages
    don't support. Queries work in any language, but Italian keywords improve
    recall against the (Italian) legal corpus.

    Args:
        query: What to search for. Keyword-dense Italian phrasing works best.
        sources: Optional subset to restrict to (see `list_tax_sources` for keys).
            Omit to search everything. Unknown keys are ignored.
        k: Max passages to return (1–12).

Input parameters:

- `k` (integer)
- `query` (string, required)
- `sources`

Output parameters:

- `count` (integer): Number of passages returned.
- `disclaimer` (string): Usage + citation guidance.
- `passages` (array): Retrieved passages, most relevant first.
- `query` (string): The query that was run.
- `sources_searched` (array): Source keys actually searched (after filtering).

### `list_tax_sources` (~55 tokens)

List the primary sources the corpus can search, and what each covers.

    Use this to discover the valid `sources` filter values for
    `search_italian_tax_sources` and to understand the corpus's coverage.

Output parameters:

- `disclaimer` (string)
- `sources` (array)

### `calculate_italian_tax` (~274 tokens)

Compute exact Italian tax for one regime at a given annual revenue.

    Deterministic calculation (not an estimate): substitute/income tax, INPS
    social contributions, net income, and effective rate. `breakdown.eligible`
    is False when the regime doesn't apply to the inputs (e.g. forfettario above
    the €85k cap) — present that as "not eligible", not as a real option.

    Args:
        revenue_eur: Gross annual revenue in EUR.
        regime: One of `forfettario_5`, `forfettario_15`, `ordinario`,
            `ordinario_impatriati`.
        coefficient: Forfettario coefficiente di redditività (0.40–0.86, set by
            the activity's ATECO group). Omit for the professional-services
            default (0.78). Ignored by non-forfettario regimes.
        cost_ratio: Deductible costs as a fraction of revenue (0–1), used by
            ordinario/impatriati. Ignored by forfettario.

Input parameters:

- `coefficient`
- `cost_ratio` (number)
- `regime` (string)
- `revenue_eur` (number, required)

Output parameters:

- `breakdown`: Full numeric breakdown (taxes, contributions, net, effective rate).
- `disclaimer` (string)

### `compare_italian_regimes` (~171 tokens)

Compare all Italian regimes side by side at one revenue level.

    Runs forfettario (5% & 15%), ordinario, and ordinario + impatriati through
    the deterministic engine and returns them sorted by net income (best first),
    each with its full breakdown and eligibility.

    Args:
        revenue_eur: Gross annual revenue in EUR.
        coefficient: Forfettario coefficiente di redditività (0.40–0.86); omit
            for the professional-services default (0.78).
        cost_ratio: Deductible costs as a fraction of revenue (0–1) for the
            ordinario regimes.

Input parameters:

- `coefficient`
- `cost_ratio` (number)
- `revenue_eur` (number, required)

Output parameters:

- `disclaimer` (string)
- `results` (array): One breakdown per regime, best net income first.
- `revenue_eur` (number): Gross annual revenue (EUR) the regimes were evaluated at.
