# bea_state_economic_trend

Calculate prior-observation and exact five-year changes for one official BEA SASUMMARY state indicator. Returns component observations, absolute and percent changes, five-year CAGR when meaningful, units, vintage evidence, and caveats. Use this for 'five-year Florida GDP trend', 'how has Ohio employment changed?', or 'California real per-capita income growth'. The optional as-of year prevents future observations from entering a historical calculation.

## Why bea_state_economic_trend is rated Low

Even though bea_state_economic_trend only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call bea_state_economic_trend to retrieve information from Livedatalink 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 Livedatalink:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bea_state_economic_trend": {}
  }
}
```
