ato-mcp

MCP server for the Australian Taxation Office corpus — cited retrieval over 29k+ ATO documents, ITAA 1997, and public rulings, plus personal-context and tax workflow tools (deduction_discovery, depreciation_helper, bas_prep_checklist, audit_risk_check).

Get your token at https://ato-mcp.com.au/onboard, then add to your MCP client config:

{
  "mcpServers": {
    "ato-mcp": {
      "command": "npx",
      "args": ["-y", "ato-mcp"],
      "env": { "ATO_MCP_TOKEN": "<your-token>" }
    }
  }
}

The client forwards every tool call to api.ato-mcp.com.au over TLS. There is no local corpus to download.

The 13 tools

Retrieval — search, get_chunks, get_doc, get_doc_anchors, get_definition, get_threshold, fetch, stats.

Personal context — get_user_facts: 25 facts captured once at onboarding so the agent never re-asks.

Workflows — deduction_discovery, depreciation_helper, bas_prep_checklist, audit_risk_check.
