Australian tax knowledge base: cited retrieval over ATO guidance, the ITAA & GST Acts, and rulings.
Most developer tooling work still happens through a UI a human drives. Ato MCP server moves it into the conversation instead. Australian tax knowledge base: cited retrieval over ATO guidance, the ITAA & GST Acts, and rulings.
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.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
The server publishes 4 tools. What each one is for:
deduction_discovery — Surfaces every deduction category that plausibly applies to your profile: a curated, cited taxonomy branched across sole traders, companiesdepreciation_helper — Deterministic prime-cost / diminishing-value / instant-write-off / small-business-pool / Div 43 schedules for any asset, with the live IAWO thresholdbas_prep_checklist — A tiered, cited BAS checklist for your reporting period: which labels apply, what evidence to gather, the gotchasaudit_risk_check — Flags the patterns the ATO scrutinises in a draft return (WRE vs income, rental anomalies, unreported crypto, …) with risk bands and the guidanceAmong the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Ato's toolset — deduction_discovery, depreciation_helper, bas_prep_checklist and 1 more — is a fair guide to whether it matches your workflow. It is maintained by au.com.ato-mcp; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Ato's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
