tax-tools is a read-only reference for United States tax information. Once added, your AI can look up tax notices, deadlines, filing screens, and estimates that are clearly labeled as estimates. It only provides information and does not file or change anything.

Details

Available today. Use it from your connected AI after setup.

After adding tax-tools, ask your AI about a US tax notice, deadline, or filing screen you want explained. Because it is read-only, it can look things up for you but cannot file or submit anything.

Install tax-tools

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

  • Claude Code

    claude mcp add --transport http --scope user tax-tools 'https://mcp.arcandledger.com/directory/mcp'

    Run it once in your project, then open /mcp to approve any sign-in the server asks for.

  • Claude Desktop

    https://mcp.arcandledger.com/directory/mcp

    Add a custom connector in Settings, paste this address, and approve the sign-in.

  • Cursor

    Open the link and Cursor adds the server at that address.

  • ChatGPT

    https://mcp.arcandledger.com/directory/mcp

    In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
