Australian Tax MCP

The Australian tax knowledge base for AI agents. Connect your AI agent to 34,500+ ATO documents (guidance, legislation, and public rulings) and get cited answers to the tax questions you'd otherwise pay your accountant to answer.

People who work with ato, australian tax and rag and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Australian Tax MCP

Claude Code

claude mcp add william-laverty-ato-mcp --transport http https://api.ato-mcp.com.au/mcp

Claude Desktop / Cursor / VS Code - add to config

    "william-laverty-ato-mcp": {
      "url": "https://api.ato-mcp.com.au/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
