## 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**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 914 tokens (~182/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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.

## MCP tools (5)

### `calculate_inflation` (~279 tokens)

Inflation calculator (CPI, 1913 to latest month)

Adjusts a dollar amount for inflation between any two periods from 1913 to the latest month the U.S. Bureau of Labor Statistics has published, using the official CPI-U (or CPI-W or core CPI). Checks the BLS Public Data API live for months newer than its bundled data (bundled through September 2026, fetched 2026-11-03), so it knows CPI figures newer than a model's training data. Handles the October 2025 gap: BLS published no October 2025 CPI because of the 2025 lapse in appropriations. Returns the adjusted amount, cumulative and average annual inflation, and the exact index values used.

Input parameters:

- `amount` (number, required): Dollar amount in the 'from' period.
- `from` (string, required): Starting period, e.g. "1995" or "2020-01": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest".
- `series` (string): cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy).
- `to` (string): Ending period, default "latest": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest".

### `get_latest_cpi` (~112 tokens)

Latest CPI release (live from BLS)

Returns the most recent CPI index values published by the Bureau of Labor Statistics, checked live against the BLS Public Data API: the latest month, the 12-month inflation rate for headline CPI-U, CPI-W and core CPI (less food and energy), the not seasonally adjusted 1-month change, and the year-to-date change. Use it to answer 'what is inflation right now'. If the live check fails it says so and falls back to bundled BLS data (through September 2026).

### `get_inflation_rate` (~153 tokens)

Annual inflation rate for a year

Returns the official U.S. inflation rate for a calendar year from BLS CPI data: annual-average change (BLS annual averages, including the 2025 average published despite the missing October 2025 index), December-to-December change, and for the current year the latest 12-month rate. Years 1914 to the present for CPI-U and CPI-W, 1958 onward for core CPI.

Input parameters:

- `series` (string): cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy).
- `year` (integer, required): Calendar year, e.g. 2025.

### `compare_raise_to_inflation` (~233 tokens)

Did a pay raise beat inflation?

Compares a pay change with CPI inflation over the same period using official BLS data through the latest published month (checked live). Returns the nominal raise, inflation, the real (inflation-adjusted) raise, the pay needed to keep pace, and the gain or shortfall. Works for salaries, hourly wages, rents or any recurring amount.

Input parameters:

- `from` (string, required): When the old pay started, e.g. "2024-01": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest".
- `new_pay` (number, required): Pay after the change, same unit.
- `old_pay` (number, required): Pay before the change (annual salary or hourly rate).
- `series` (string): cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy).
- `to` (string): When to measure, default "latest": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest".

### `calculate_social_security_cola` (~137 tokens)

Social Security COLA from CPI-W

Computes the Social Security cost-of-living adjustment for a year with the statutory formula: average CPI-W for July-September of the prior year over the same quarter a year earlier, rounded to 0.1%. Uses official BLS CPI-W values (live check). Reproduces the 3.6% COLA for 2027 that SSA announced in October 2026, and shows the Q3 index values behind it. Covers 1976 onward.

Input parameters:

- `cola_year` (integer, required): Year the COLA is paid, e.g. 2027 (measured on Q3 2026 CPI-W).
