Run CLI-based inflation calculations with this MCP Server

This MCP brings `compute_absolute_inflationary_erosion` directly to your terminal to expose how much cash value has dissolved. Stop guessing about how inflation affects your cash reserves and let the command line do the math. Your agent calls this tool during automated cron jobs or data processing scripts. It pipes the exact cash decay figures straight into your reports without any manual steps.

Audit your true buying power from the terminal

The `calculate_purchasing_power_ratio` tool calculates the exact ratio of purchasing power your capital preserves over time. It is a brutal sanity check for any long-term financial model or backtest you run. You can have your agent fetch this ratio to verify if your historical database yields are real or fake. It helps you build terminal-based dashboards that show honest financial performance.

Script precise real returns

You get `get_real_return_percentage` to calculate the exact real return rate using the Fisher equation directly in your shell. Simple subtraction is for amateurs who do not mind being wrong about their money. Claude Code uses this tool to process large batches of nominal yields against CPI data. It outputs clean, precise math that you can pipe into other command-line tools.

Common questions about Inflation-Adjusted Return Calculator MCP in Claude Code

Run the add command in your terminal using the HTTP transport flag. Your CLI client will save the configuration and make the tools available instantly.

Yes, you can pipe your raw financial numbers directly into the tool commands. Your agent can run these calculations inside headless shell environments or CI/CD pipelines.

The local mathematical tools run entirely offline once installed. If your agent needs to fetch current inflation rates from an external API, it will handle that separately.

Your agent calls the Fisher equation tool with your nominal rate and inflation inputs. It outputs the exact real rate of return directly to your terminal.

No, it never stores or logs your interest rates or portfolio balances. The calculations are processed in memory and outputted directly to your standard terminal stream.
