What list_indexes does on Mcpg

AI agents call list_indexes 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.

Why list_indexes is rated Low

While the empty description reduces confidence slightly, the tool name itself strongly suggests a non-destructive information retrieval operation with minimal security impact.

From the tool's definition Tool name 'list_indexes' indicates a query operation that retrieves index metadata from PostgreSQL. No description provided, but the naming pattern aligns with standard database introspection operations (list, get, fetch).

The rule that runs list_indexes 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 list_indexes, this is the rule to start with:

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