WHAT IT DOES

What describe_ao_table does on Mcpg

AI agents call describe_ao_table to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why describe_ao_table is rated Low

The verb 'describe' combined with 'table' strongly indicates a READ operation that retrieves schema or structure information about a PostgreSQL table (likely an Append-Only table variant). No side effects, modification, deletion, or execution semantics are evident. Low severity due to information-only scope.

From the tool's definition Tool name 'describe_ao_table' suggests metadata inspection of an Append-Only table; typical of descriptor/inspection operations that retrieve but do not modify data. No description provided to contradict this inference.

RECOMMENDED RULE

The rule that runs describe_ao_table safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For describe_ao_table, this is the rule to start with:

describe_ao_table Allowed

describe_ao_table is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "describe_ao_table": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcpg, apply this rule, and every describe_ao_table call is checked against it from then on.
