taxcode.au Connect MCP

ChatGPT setup

Create a taxcode.au app in ChatGPT.

Use ChatGPT Developer mode to create an app from the hosted taxcode.au remote MCP server. Then select it in a conversation when Australian tax research needs source-backed retrieval.

MCP server URL https://mcp.taxcode.au/

Before you start

  • Use ChatGPT on the web with an account that has Developer mode available.
  • Workspace admins may need to allow custom apps or Developer mode.
  • taxcode.au uses remote Streamable HTTP MCP with OAuth.

Create the app

  1. Open Settings > Apps > Advanced settings.
  2. Enable Developer mode.
  3. Return to Apps and choose Create app.
  4. Enter https://mcp.taxcode.au/ as the remote MCP server URL.
  5. Choose OAuth authentication when prompted.
  6. Scan tools, authorize the connection, and create the app.

Use it in a conversation

  1. Open a new chat.
  2. Choose Developer Mode from the composer tools.
  3. Select the taxcode.au app for the conversation.
  4. Ask explicitly for taxcode.au when you need source-grounded Australian tax research.
Prompt

Use taxcode.au only. Find source-backed guidance on Division 7A loan repayment timing and list the compliance risks I should review.

Review tool output

  • Expand tool calls when needed to inspect returned source metadata.
  • Refresh the app from ChatGPT app settings if the MCP server adds or changes tools.
  • Ask for jurisdiction, date, source-gap, and anti-avoidance checks before relying on a strategy answer.
  • Treat the result as research support, not legal or tax advice.
