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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "pg_text_to_query",
    "arguments": {}
  }
}
```

## Why pg_text_to_query is rated Low

pg_text_to_query performs query transformation for full-text search—a read-only operation that retrieves or prepares search queries without side effects. It does not modify, delete, or execute arbitrary operations. The tool accepts user input but constrains it to converting text into a standardized query format (tsquery), which is a safe, bounded operation.

From the tool's own definition: "Tool converts text to tsquery for full-text search with modes like 'plain', 'phrase', and 'websearch'. This is a data retrieval operation (search) with no mention of modification, deletion, or execution of arbitrary code."

## Use case

AI agents call pg_text_to_query 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_to_query": {}
  }
}
```
