Terminal-Based Bond Valuation

Run `calculate_bond_valuation` via the command line to get instant YTM data for your sovereign bond positions. This is for the SRE or dev who needs immediate answers without a GUI. This MCP plugs directly into your shell workflow. You can pipe bond data through it and get clean, calculated output ready for your next report.

Currency Yield Parity

Foreign sovereign debt requires `calculate_currency_equivalent_yield` to be useful. This MCP lets you run these conversions as part of your CI/CD pipelines or cron jobs. It handles the parity math so you don't have to write custom scripts. The math doesn't lie, and this gives you a reliable way to track international yields from the terminal.

Inflation-Adjusted Returns

Use `calculate_inflation_adjusted_return` to automate the assessment of real returns on your bond portfolio. It is the only way to see if you are actually gaining ground against inflation. This MCP gives you the real yield figures needed for your macro analysis scripts. Bottom line, it keeps your data grounded in economic reality.
