## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_italian_tax`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
    
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `compare_italian_regimes`

- The name "compare_italian_regimes" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "list_tax_sources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "search_italian_tax_sources" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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).
    
```
