Mcp Builders. ausdata.io

If you are building Model Context Protocol servers --- for agents, IDEs, AI tools --- and you need clean Australian government data inside the tools you ship, ausdata.io is built for you.

We maintain 9 sister MCP servers covering Australia main public data sources, plus a hosted REST API behind them. All sisters are open source on PyPI. Use them directly, fork them, contribute back.

The 9 sister MCP servers

Package Source Licence

abs-mcp Australian Bureau of MIT Statistics

rba-mcp Reserve Bank of MIT Australia

ato-mcp Australian Taxation MIT Office

apra-mcp Australian Prudential MIT Regulation Authority

aihw-mcp Australian Institute of MIT Health and Welfare

asic-mcp Australian Securities MIT and Investments
Commission

aemo-mcp Australian Energy MIT Market Operator

wgea-mcp Workplace Gender MIT Equality Agency

`au-weather-mcp` Bureau of Meteorology MIT via Open-Meteo

Each sister exposes 5 core tools:

search_<source>(query, limit) --- fuzzy search across known datasets
describe_<source>(id) --- schema + filter values
get_data(id, filters, start_period, end_period) --- query
latest(id, filters) --- current snapshot
list_curated() --- enumerate supported IDs

Two ways to use

Option 1: Direct (per-sister, pip-installed)

pip install rba-mcp

Then in your MCP host config:

{
  "mcpServers": {
    "rba": {
      "command": "python",
      "args": ["-m", "rba_mcp"]
    }
  }
}

Free, MIT-licensed, no API key required. Best for personal projects, hobbyist tools, open-source contributions.

Option 2: Unified hosted (one server, all 9 sources)

npx ausdata-mcp

Then in your MCP host config:

{
  "mcpServers": {
    "ausdata": {
      "command": "npx",
      "args": ["ausdata-mcp"],
      "env": { "AUSDATA_API_KEY": "ak_YOUR_KEY" }
    }
  }
}

Plus the composer endpoints (real_rate_regime, inflation_decomposition, etc.) as additional tools. Free tier 500 calls/month. Best for production tools and AI agents.

Why choose option 1 vs option 2

Option 1 (sister MCPs directly):

Free, no key needed
Fork and modify each sister
Contribute back via PR
Best for personal projects and hobbyist tools

Option 2 (hosted unified):

One key, one envelope, one upgrade path
Composer endpoints (cross-source signals)
Webhooks on dataset releases
Caching + stale-fallback + reliability
Best for production tools

Many MCP builders start with option 1 to evaluate, then move to option 2 when they ship to production.

Contributing back

Each sister is open source on GitHub at Bigred97/<source>-mcp. We welcome:

Bug fixes
New datasets within the sister scope
Improvements to filter mapping
Test coverage
Documentation improvements

For new datasets outside the existing 9 sources, open an issue first to discuss scope.

Building your own MCP using ours

If you are building a vertical MCP (e.g. "Australian financial planner copilot") and need AU public data as a subset, you have two paths:

Import our sisters or call our hosted API directly inside your tool
Fork the relevant sister and customise the tool surface for your use case

The MIT licence permits both. Attribution is appreciated but not required.

Why this matters for MCP builders

Three reliability issues MCP-only solutions hit without ausdata:

Per-source maintenance burden. Building 9 sister servers from scratch is 6-12 months of work. We did that work.
Schema drift. ABS, RBA, AEMO change their data formats periodically. We track and adapt; you inherit the stability.
Cross-source composition. No single sister can answer "what is the current real cash rate" because that requires joining ABS + RBA. The hosted API exposes the join.

Pricing for MCP builders

Per-sister (option 1): free forever, MIT-licensed.
Hosted unified (option 2): free tier 500 calls/month covers most personal use. Paid tiers $29-99/mo for production.
