Seven independently released Python engines that apply Australian tax and payroll rules to figures you supply, plus Aus Accounting MCP, a local Model Context Protocol server that hands those engines to an AI assistant. It serves Australian accountants and bookkeepers, and the developers who build tooling for them.
Each tool returns a calculation, the facts it used and the matters it refuses to decide. The engines and the MCP server run locally: they read files you point them at, contact no service, write to no ledger and lodge nothing. Two boundaries sit outside that: an MCP host sends every tool argument and result to its model provider, and the optional LodgeiT adapter below makes bounded HTTP calls only when you enable it. Missing facts stay unknown: a Payday Super row with a fund-receipt date but no matchedamount or remittedamount evidences when the fund received something, not how much, so the checker leaves it UNKNOWN rather than ON_TIME and names the amount it needs (from payda
