# cftc_cot_history

Return a bounded weekly history for one CFTC contract market, report family, scope, and trader category from the self-hosted official snapshot. Includes long, short, spreading, net, changes, percentages, open interest, pagination, source ids, and provenance. Use this for 'managed money net positions in crude oil over time', 'commercial gold COT history', or a reproducible positioning chart. Report-family categories are enforced; not trading advice.

## Why cftc_cot_history is rated Low

Even though cftc_cot_history 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 cftc_cot_history 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": {
    "cftc_cot_history": {}
  }
}
```
