Common questions, answered plainly

No. ato-mcp retrieves published ATO material and runs fixed calculations, always with the source attached. Confidence ratings and risk bands are guides, not professional judgement. Your agent does the reasoning, and decisions that matter should still go past a registered tax agent.

Your onboarding facts (business structure, GST registration and so on, about 25 fields you control), your sign-in identity, and basic usage counts. Never tool names, never query content, never results: the database physically has nowhere to store them, and the privacy page is generated from that same schema so it can't drift.

Yes. ato-mcp is an MCP server for Australian tax: it gives any agent that speaks the Model Context Protocol (Claude, ChatGPT, Codex, Gemini CLI, Cursor, VS Code) cited retrieval over 34,500+ ATO documents, the income tax and GST Acts and 4,900+ public rulings.

MCP is the open standard AI agents use to call outside tools and data sources. ato-mcp uses it to hand your agent 13 Australian tax tools: search over the corpus, statutory definitions, current rates and thresholds, and four workflow tools, with every answer carrying its ATO citation.

The corpus is rebuilt from ato.gov.au, the Federal Register of Legislation and law.ato.gov.au on a monthly cycle and served fresh. The stats tool reports the live snapshot.

Most clients connect directly to the hosted endpoint with no local code at all. The optional npm client is open source (AGPL-3.0) and public, so you can verify exactly what it does. The hosted retrieval platform and the corpus are maintained privately.

Three: ato.gov.au guidance, the legislation itself (the ITAA 1997, ITAA 1936 and GST Act, section by section, with 2,310 statutory definitions) and 4,900+ ATO public rulings across ten series, with withdrawn rulings flagged. The corpus is rebuilt monthly and served fresh.

Thirteen tools. Nine retrieval tools cover search, whole documents, statutory definitions, current rates and thresholds and the citation graph. A personal-context tool carries your tax profile into every answer. Four workflow tools handle deduction discovery, depreciation schedules, BAS preparation and audit-risk checks, all cited.

One line in your client, or a short config paste, then sign in with your browser. Your account is created on first sign-in and there is no token to copy. The install page has the exact command for each client.

No. If you can paste a command and sign in with your browser, you can connect ato-mcp. The install page walks through each client step by step.

If you want it to. You can save a tax profile (about 25 fields: business structure, GST registration and so on) that your agent reads once per session, so answers fit a sole trader registered for GST rather than a generic taxpayer. It's optional, and you control every field.

Yes. Account deletion removes your profile and sign-in identity. There are no stored queries or results to delete, because the database has nowhere to put them. The privacy page lists every stored field, generated from the schema itself.
