Key Capabilities
Automate tax math in Windsurf
Cascade pulls your service data and runs `calculate_tax_liability` to determine exactly what you owe. You avoid manual math errors by letting the agent handle the heavy lifting. Windsurf chains these operations to ensure your financial records stay accurate. It processes the numbers while you focus on higher-level tasks.
Check withholding requirements
The agent uses `check_withholding_status` to verify if your current project triggers tax obligations. You get an immediate answer without digging through regulatory documents. This MCP keeps your workflow moving by providing clear status reports. It prevents unexpected tax hits before you finalize your invoices.
Sync local rates instantly
You can call `get_applicable_rate` to pull the precise tax percentage for any specific municipality. Windsurf identifies the right rate for your service type automatically. This data integration keeps your billing logic current. You stop guessing rates and start shipping accurate invoices every time.
