- Look up IRS notice codes and understand typical response paths for a given notice type.
- Check filing deadlines, payment dates, and common federal tax calendar milestones.
- Estimate federal penalties, quarterly tax payments, rental income results, and other tax calculations based on provided inputs.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
