- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_italian_tax_sources (destructiveHint, idempotentHint); list_tax_sources (destructiveHint, idempotentHint); compare_italian_regimes (destructiveHint); …
- pass `tools.token_cost`: about 1,061 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 1,061 tokens to load them all
- tool set hash: 65b587dabb58a4d82967239c5d01dacb
- badge: [![protogrid quality](https://protogrid.dev/badge/it.taxcompass/taxcompass.svg)](https://protogrid.dev/servers/it.taxcompass/taxcompass)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `calculate_italian_tax`: 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.
    
- `compare_italian_regimes`: 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.
    
- `list_tax_sources`: 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.
    
- `search_italian_tax_sources`: 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).
