## Why pg_text_headline is rated Low

This tool performs a read-only operation that retrieves and formats search results. It queries existing data to generate highlighted text snippets for display purposes, which is characteristic of Read category tools. No data is created, modified, deleted, or executed - only retrieved and formatted for presentation.

From the tool's own definition: "Tool generates highlighted snippets from full-text search matches with a select parameter for row identification. The description indicates data retrieval and formatting operations with no modification, deletion, or execution capabilities."

## Use case

AI agents call pg_text_headline to retrieve information from PostgreSQL MCP Server 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 PostgreSQL MCP Server:

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