Script Your Tax Calculations

Run tax calculations from your terminal, no browser needed. This is built for scripting and automation. Pipe your gross revenue to `get_taxable_base`, then chain the result into `calculate_cit_breakdown` and `calculate_scll_liability` as part of any shell script.

Automate Financial Reporting in CI

Set up a cron job or a GitHub Action to automatically generate financial reports. This MCP makes it easy to add tax calculations to any automated workflow. On a schedule, your CI runner can invoke Claude Code to call `generate_tax_summary_report` with the latest revenue data and upload the output to a storage bucket or send it via a webhook.

Headless Tax Modeling with this MCP Server

This MCP Server is perfect for running batch calculations. You can feed it a CSV of revenue figures and activity types for headless processing. Write a simple script that reads each line, calls the calculation tools via Claude Code, and outputs a new CSV with the corresponding tax liabilities.
