Available components
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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the TaxCompass — Italian tax tools MCP server?
TaxCompass — Italian tax tools is a hosted endpoint at https://api.taxcompass.it/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_italian_tax ~274
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.
| Name | Type | Req | Description |
|---|---|---|---|
| coefficient | – | – | – |
| cost_ratio | number | – | – |
| regime | string | – | – |
| revenue_eur | number | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| breakdown | – | yes | Full numeric breakdown (taxes, contributions, net, effective rate). |
| disclaimer | string | yes | – |
No examples provided.
compare_italian_regimes ~171
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.

| results | array | yes | One breakdown per regime, best net income first. |
| revenue_eur | number | yes | Gross annual revenue (EUR) the regimes were evaluated at. |
No examples provided.
list_tax_sources ~55
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.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| disclaimer | string | yes | – |
| sources | array | yes | – |
No examples provided.
search_italian_tax_sources ~264
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).
| Name | Type | Req | Description |
