## 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 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1015 tokens (~253/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `calculate_estate_tax` (~337 tokens)

Federal estate tax calculator (Form 706 method)

Years 2013-2026. Uses $15,000,000 for 2026 deaths (P.L. 119-21), $13,990,000 for 2025. Federal only.

- `dsue` (number): Deceased spousal unused exclusion (portability) from the last deceased spouse's timely Form 706. Default 0.
- `gift_tax_payable` (number): Gift tax payable on those gifts, figured at date-of-death rates (Form 706 line 7). Usually 0 if lifetime gifts stayed under the exemption. Default 0.
- `gross_estate` (number, required): Gross estate at fair market value on the date of death, in dollars.
- `lifetime_taxable_gifts` (number): Adjusted taxable gifts made after 1976 (gifts above the annual exclusion, as reported on Form 709). Default 0.
- `year` (integer): Year of death, 2013-2026. Default 2026.

### `check_gift` (~309 tokens)

Gift tax check: annual exclusion, gift splitting, spouse rules

Checks a gift against the federal gift tax rules for a year (2013-2026): annual exclusion per recipient ($19,000 in 2025 and 2026), gift splitting with a spouse (sec. 2513, doubles it to $38,000), unlimited marital deduction for a US citizen spouse, and the separate annual exclusion for a non-citizen spouse ($190,000 in 2025, $194,000 in 2026 under Rev. Procs. 2024-40 and 2025-32). Returns taxable gifts, whether Form 709 is required, lifetime exemption used and left (2026: $15,000,000), and any gift tax due.

Input parameters:

- `amount` (number, required): Gift amount per recipient, in dollars.
- `gift_splitting` (boolean): Elect gift splitting with your spouse (both consent on Form 709). Default false.
- `prior_taxable_gifts` (number): Your taxable gifts in earlier years (lifetime exemption already used). Default 0.
- `recipient_type` (string): individual (anyone but your spouse, default) or spouse.
- `recipients` (integer): Number of recipients each getting that amount. Default 1.
- `spouse_citizen` (boolean): For recipient_type spouse: whether the spouse is a US citizen. Required for spouse gifts.
- `year` (integer): Year of the gift, 2013-2026. Default 2026.

### `compare_years` (~166 tokens)

Compare estate and gift tax exemptions between years

Compares two years (2013-2026) side by side: basic exclusion amount, applicable credit, annual gift exclusion and non-citizen spouse exclusion, and, with a taxable estate, the federal estate tax in each year. Default 2025 vs 2026, the year P.L. 119-21 raised the exemption to $15,000,000 instead of letting it fall to about half.

Input parameters:

- `taxable_estate` (number): Optional taxable estate (after deductions, no lifetime gifts or DSUE) to price in both years.
- `year_a` (integer): First year, 2013-2026. Default 2025.
- `year_b` (integer): Second year, 2013-2026. Default 2026.
