What it does

An MCP server that exposes a deterministic calculator engine for 530A custodial retirement account (Trump Account) projections. It lets developers run financial scenarios, retrieve calculation rules, and search account-related information without authentication or setup.

  • Run 530A account balance projections with custom contribution amounts, growth rates, and time horizons.
  • Retrieve the current legal rules and verified figures that govern 530A account limits and tax treatment.
  • Search guides and explanations about 530A account mechanics to answer user questions in real-time.

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.
