Model Context Protocol (MCP) server for freee API integration
Nothing to run from here
CPI Inflation Calculator is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

claude mcp add --scope user --transport http cpi-inflation-calculator-mcp https://cpi-inflation-calculator-mcp.lipmichal.workers.dev/mcp
# 2 — ask your agent for something these tools do
# calculate_inflation, get_latest_cpi, get_inflation_rate and 2 more
CPI Inflation Calculator costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.

One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

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
| Parameter | Type | Required | Notes |
|---|---|---|---|
| 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". |
| to | string | no | Ending period, default "latest": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest". |
| series | string | no | cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy). |
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
No parameter schema on file.
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| year | integer | yes | Calendar year, e.g. 2025. |
| series | string | no | cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy). |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| old_pay | number | yes | Pay before the change (annual salary or hourly rate). |
| new_pay | number | yes | Pay after the change, same unit. |
| from | string | yes | When the old pay started, e.g. "2024-01": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest". |
| to | string | no | When to measure, default "latest": "YYYY" for the annual average, "YYYY-MM" for one month, or "latest". |
| series | string | no | cpi_u (default, the headline CPI), cpi_w (wage earners, used for Social Security COLAs) or core (CPI-U less food and energy). |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| cola_year | integer | yes | Year the COLA is paid, e.g. 2027 (measured on Q3 2026 CPI-W). |

Release 1.0.0 · scanned 4 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
