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
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability73
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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

calculate_inflation Inflation calculator (CPI, 1913 to latest month) ~279
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.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | number | yes | Dollar amount in the 'from' period. |
| from | string | yes | 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". |

calculate_social_security_cola Social Security COLA from CPI-W ~137
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.
| Name | Type | Req | Description |
|---|---|---|---|
| cola_year | integer | yes | Year the COLA is paid, e.g. 2027 (measured on Q3 2026 CPI-W). |
No output schema declared.
No examples provided.
compare_raise_to_inflation Did a pay raise beat inflation? ~233
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.
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | yes | When the old pay started, e.g. "2024-01": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest". |
| new_pay | number | yes | Pay after the change, same unit. |
| old_pay | number | yes | 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". |
No output schema declared.
No examples provided.
get_inflation_rate Annual inflation rate for a year ~153
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Calendar year, e.g. 2025. |
No output schema declared.
No examples provided.
get_latest_cpi Latest CPI release (live from BLS) ~112
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).
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
How do I install the CPI Inflation Calculator MCP server?
CPI Inflation Calculator is a hosted endpoint at https://cpi-inflation-calculator-mcp.lipmichal.workers.dev/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.
