Ato MCP server

What it does

This server connects AI agents to a knowledge base of 34,500+ Australian Taxation Office (ATO) documents, including guidance, legislation, and public rulings. It enables agents to retrieve cited answers to Australian tax questions by searching and referencing official ATO materials.

• Ask tax questions about Australian income tax, GST, or capital gains and receive answers with citations to relevant ATO guidance or legislation.
• Look up current tax thresholds, deductions limits, or compliance requirements that change annually.
• Research specific tax rulings or legislative sections to understand how a tax rule applies to a particular situation.

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.
