## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 20 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 835 tokens (~278/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

US Take-Home Pay Calculator

Computes net take-home pay for a US W-2 employee: federal income tax, state income tax (all 50 states + DC), FICA (Social Security + Medicare + Additional Medicare), and state-specific extras (e.g. CA SDI, OR transit tax). Supports pre-tax 401(k) and health-insurance deductions and per-paycheck breakdowns. Example input: { "gross": 75000, "state": "CA", "filingStatus": "single" }. 2026 tax year — estimates, not tax advice; brackets from Tax Foundation (Jan 1, 2026) & IRS.

- `filingStatus` (string, required): IRS filing status.
- `gross` (number, required): Annual gross income in USD, e.g. 75000.
- `payFrequency` (string): Pay frequency; the result always includes a full per-paycheck breakdown for all frequencies regardless of this value.
- `pretax401kPct` (number): Pre-tax 401(k) contribution as a percent of gross pay (0-100), capped at the 2026 employee deferral limit ($23,500).

### `self_employment_tax` (~223 tokens)

Self-Employment (1099) Tax Calculator

Computes Schedule SE self-employment tax (15.3% = 12.4% Social Security up to the wage base + 2.9% Medicare on 92.35% of net profit), the Additional Medicare surtax, federal income tax, and an optional state income tax, plus a quarterly estimated-payment figure. Example input: { "netProfit": 90000, "filingStatus": "single", "state": "TX" }. 2026 tax year — estimates, not tax advice; brackets from Tax Foundation (Jan 1, 2026) & IRS.

- `state` (string): Optional two-letter US state or DC postal code to also estimate state income tax.

### `capital_gains_tax` (~289 tokens)

Capital Gains Tax Calculator

Computes federal capital gains tax (long-term 0%/15%/20% stacked bands or short-term ordinary rates), the 3.8% Net Investment Income Tax (NIIT) above the MAGI threshold, and an optional state income tax on the gain (states generally tax capital gains as ordinary income). Example input: { "gain": 50000, "ordinaryTaxableIncome": 80000, "filingStatus": "single", "term": "long" }. 2026 tax year — estimates, not tax advice; thresholds from Rev. Proc. 2025-32, cross-checked against Tax Foundation & Schwab.

Input parameters:

- `filingStatus` (string, required): IRS filing status.
- `gain` (number, required): Gross capital gain in USD (sale price minus cost basis), e.g. 50000.
- `ordinaryTaxableIncome` (number, required): Other taxable income (excluding the gain), which sets the long-term capital gains bracket and NIIT threshold.
- `state` (string): Optional two-letter US state or DC postal code; most states tax the gain as ordinary income.
- `term` (string, required): "long" for assets held > 1 year (preferential rates), "short" for ordinary rates.
