# unsdg.data.query

Query UN SDG time-series indicator data by series code. Returns country-level or regional annual measurements for indicators like poverty rates, maternal mortality, CO2 emissions, literacy rates, and more. Filter by UN M49 geo area code (e.g. "356" for India, "840" for USA) and/or year range. Each record includes the geo area, year, value, source, and any disaggregation dimensions (age, sex, urbanization). Get series codes from unsdg.indicators.list; get geo area codes from unsdg.geo.countries.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `limit` | integer | no | Maximum number of records to return per page (1-200, default 50). Large series may have thousands of records across countries and years. |
| `end_year` | integer | no | Filter data records up to and including this year (e.g. 2023). Combined with start_year to define a time range. |
| `start_year` | integer | no | Filter data records starting from this year (e.g. 2010). Combined with end_year to define a time range. |
| `series_code` | string | yes | UN SDG series code to query (e.g. "SI_POV_DAY1" for poverty rate, "SH_STA_MORT" for maternal mortality, "EN_ATM_CO2" for CO2 emissions). Obtain series codes fro |
| `geo_area_code` | string | no | UN M49 numeric geo area code to filter by country or region (e.g. "356" for India, "840" for USA, "076" for Brazil). Use unsdg.geo.countries to look up codes. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "unsdg.data.query",
    "arguments": {
      "series_code": "<series_code>"
    }
  }
}
```

## Why unsdg.data.query is rated Low

Tool queries and retrieves public UN statistical data with no modification, deletion, or execution capabilities.

From the tool's own definition: "Query UN SDG time-series indicator data, Returns country-level measurements, Filter by geo area code and year range."

## Use case

AI agents call unsdg.data.query to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "unsdg.data.query": {}
  }
}
```
