# autario-mcp
**Verified data for AI agents.** 2,700+ public datasets (World Bank, FRED, Eurostat, OECD, WHO, ECB, US Census, IMF) joined under one ontology, with built-in statistical analysis and chart publishing. Plug it into Claude Desktop, ChatGPT, Cursor, or any MCP-compatible client | your model gets numbers it cannot hallucinate.

## Why autario-mcp
- **No hallucinated numbers.** Every value is sourced from a known publisher and cited back to a primary URL. Use `verify_value` to double-check any claim.
- **Cross-dataset joins, no setup.** Indicators across different datasets share `autario_time` + `autario_entity` shadow columns, so `get_entity_data(USA, [gdp, unemployment, life_expectancy])` returns one wide table, joined automatically.
- **Statistical primitives built-in.** `correlate`, `regression`, `find_drivers`, `lag_analysis`, `seasonality_decomposition` and more, with effect sizes, p-values, and plain-language interpretations.
- **Charts that persist.** `publish_chart` writes a Plotly spec to autario.com. The result is a permanent, embeddable URL like `autario.com/chart/{slug}` | the LLM builds the spec, autario pulls real rows for it, no hallucinated data path.
- **LLM-agnostic.** Works with Claude, GPT, Gemini, local models | anything that speaks MCP.
## Quick Demo
Install the server, then ask your assistant questions like these. The model picks the right tools and answers with cited data.
```text
Ask: "What drives US inflation? Look at money supply, oil prices, and unemployment."
Tools: list_indicators -> find_drivers
Output: Ranked drivers with r, p-value, R squared per candidate.
```
```text
Ask: "Compare life expectancy in Germany, USA and Japan from 2000 to 2023, then publish a chart."
Tools: compare_entities -> publish_chart
Output: Wide-format table joined on year, plus a permanent autario.com/chart/{slug} URL.
```
```text
Ask: "Is consumer confidence a leading indicator of US retail sales?"
Tools: lag_analysis
Output: Cross-correlation peak at lag k, with interpretation in months.
```
## Install
### Claude Desktop, Cursor, Cline (stdio)
`~/.config/claude/claude_desktop_config.json` on Mac/Linux, `%APPDATA%\Claude\claude_desktop_config.json` on Windows.
```json
{
"mcpServers": {

"command": "npx",
"args": ["autario-mcp"]
}
}
}
```
Restart your client. The server reports tool count to stderr on launch.
### Claude Web, OpenAI Custom GPTs, any HTTP MCP client
Point your client at the hosted endpoint. No install needed.

URL: https://autario.com/mcp
Transport: Streamable HTTP (POST /mcp)
```
The hosted endpoint also supports MCP prompts: `analyze-dataset`, `create-chart`, `compare-countries`.
### Enable write tools (publish charts, create datasets)
Add API credentials to the stdio config or send them as `x-api-key` / `x-api-secret` headers to the HTTP endpoint.
```json
{
"mcpServers": {
"autario": {
"command": "npx",
"args": ["autario-mcp"],

## Development
This package is part of the [autario monorepo](https://github.com/autario/autario). Tool definitions live in `tools.js` (single source of truth, shared with the HTTP transport in `remote.js`). The Tool Reference section above is auto-generated.
```bash
# regenerate the README Tool Reference from tools.js
npm run build-readme
