[CI] [npm] [License: AGPL-3.0] [Node 22+]

Quick start

Add the MCP Server to the client you already use.

Standard config works with most tools that run stdio servers:

json
{  "mcpServers": {    "ato": {      "command": "npx",      "args": ["-y", "ato-mcp"]    }  }}
bash
npm install -g ato-mcp   # optional, npx works without installing

For hosts that natively support remote MCP servers, connect your client directly:

Claude Code
bash
claude mcp add --scope user --transport http ato https://api.ato-mcp.com.au/mcp

Then run /mcp inside Claude Code, select ato, and choose Authenticate. Your browser opens to sign in.

Codex CLI
bash
codex mcp add ato --url https://api.ato-mcp.com.au/mcpcodex mcp login ato

codex mcp login opens your browser to sign in.

Gemini CLI
bash
gemini mcp add --scope user --transport http ato https://api.ato-mcp.com.au/mcp

Gemini CLI detects the auth challenge on first use and opens your browser automatically.

VS Code (Copilot)

[Install in VS Code] [Install in VS Code Insiders]

Or from the command line:

bash
code --add-mcp '{"name":"ato","type":"http","url":"https://api.ato-mcp.com.au/mcp"}'

VS Code prompts to authenticate in your browser when the server first connects.

Cursor

[Install in Cursor]

Or add to ~/.cursor/mcp.json:

json
{  "mcpServers": {    "ato": {      "url": "https://api.ato-mcp.com.au/mcp"    }  }}

Cursor shows a "Needs login" prompt on the server. Click it to sign in via your browser.

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

json
{  "mcpServers": {    "ato": {      "type": "streamable-http",      "serverUrl": "https://api.ato-mcp.com.au/mcp"    }  }}

If Windsurf doesn't open a sign-in window, use the standard npm config at the top of this section instead; it handles the browser sign-in itself.

Claude.ai / Claude Desktop
  1. Open Settings → Connectors
  2. Add custom connector
  3. Paste https://api.ato-mcp.com.au/mcp
  4. Click Connect and sign in when the browser window appears

Available on paid Claude plans. Claude Desktop can alternatively use the standard npm config at the top of this section in claude_desktop_config.json.

ChatGPT
  1. Settings → Apps & Connectors → enable Developer Mode
  2. New connector → paste https://api.ato-mcp.com.au/mcp
  3. Choose OAuth and sign in when prompted

Requires a plan with connector support.

Other (OpenCode, Zed, etc)

Use the standard npm config at the top of this section. This package bridges any stdio host to the hosted server with the same browser sign-in.

What's in the corpus

Everything the ATO publishes, in one searchable place, refreshed monthly:

SourceContents
ato.gov.au23,000+ guidance pages, forms & instructions, occupation guides, myTax help
LegislationITAA 1997, ITAA 1936 and the GST Act: 6,468 sections + 2,310 statutory definitions (point-in-time aware)
ATO public rulings4,900+ rulings across 10 types (TR, TD, GSTR, GSTD, PR, CR, LCR, PCG, MT, FTR), withdrawn rulings flagged
Cross-references64,217 links between rulings and legislation
ThresholdsTime-keyed values (instant asset write-off, GST registration, CGT discount, super caps, …)

34,500+ documents (286,000+ searchable passages), refreshed monthly and served from the hosted platform.

The 13 tools

Workflows are the reason this exists:

"Here's my bank transactions, what can I claim this year? How do I write off my new laptop? Is anything in my return risky?"

ToolWhat it does
deduction_discoverySurfaces every deduction category that plausibly applies to your profile: a curated, cited taxonomy branched across sole traders, companies, trusts, partnerships, investors and SMSF members
depreciation_helperDeterministic prime-cost / diminishing-value / instant-write-off / small-business-pool / Div 43 schedules for any asset, with the live IAWO threshold
bas_prep_checklistA tiered, cited BAS checklist for your reporting period: which labels apply, what evidence to gather, the gotchas
audit_risk_checkFlags the patterns the ATO scrutinises in a draft return (WRE vs income, rental anomalies, unreported crypto, …) with risk bands and the guidance behind each flag

Every workflow tool returns structured data and resolvable ATO citations, never advice in its own voice.

Personal context: get_user_facts, 25 facts captured once at onboarding (business structure, GST registration, investments, super type, residency, …) so the agent never re-asks.

Retrieval: search (keyword and semantic retrieval), get_chunks, get_doc, get_doc_anchors (cross-references), get_definition (statutory, point-in-time), get_threshold (time-keyed values), fetch (live page fetch), stats.
