Why getTableSchema needs a policy

This tool retrieves schema information from a table, which is a read-only query operation. The empty description reduces confidence slightly, but the name strongly suggests data retrieval without side effects. Even if it reads sensitive schema details, the blast radius for an AI misusing this tool is limited to information disclosure rather than data modification, deletion, or execution of arbitrary operations.

From the tool's definition Tool name 'getTableSchema' indicates retrieval of database/table schema information. No description provided, but schema inspection is a read-only operation that retrieves structural metadata without modification.

Documented attack patterns abuse exactly the kind of access getTableSchema gives an agent:

How to control getTableSchema

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Server Generator, and nothing reaches the server without passing your rules. This is the rule we recommend for getTableSchema:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "getTableSchema": {}
  }
}

getTableSchema is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register MCP Server Generator — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
