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

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

## Why pg_dump_schema is rated Low

pg_dump is a standard PostgreSQL export utility used for backing up or inspecting schema structure. While the tool retrieves potentially sensitive schema information, it does not modify, delete, execute arbitrary code, or commit financial transactions. The operation is read-only with no destructive capability.

From the tool's own definition: "Tool name 'pg_dump_schema' and description 'Get the pg_dump command for a schema or database' indicate retrieval of schema definition."

## Use case

AI agents call pg_dump_schema 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_dump_schema": {}
  }
}
```
