# pm_market_overview

Forensic overview of the most active Polymarket markets: coverage, bucket distribution (concentrated/broad/structurally-thin/moderate/unranked) and the top decomposed markets (taker concentration, effective traders, dominant flow, on-chain counterparties, resolution context). Descriptive PER-WINDOW fact, never an allegation. Apparent volume is not liquidity.

## Why pm_market_overview is rated Low

Even though pm_market_overview 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 pm_market_overview to retrieve information from Pm 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 Pm:

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