WHAT IT DOES

What show_query_log does on Teradata Workload Management (WLM) MCP Server

AI agents call show_query_log to retrieve information from Teradata Workload Management (WLM) MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why show_query_log needs a policy

This is a read-only operation that queries and displays historical data from Teradata's query logs. However, it retrieves sensitive performance and execution details including actual SQL queries and resource consumption metrics that could be used to identify business logic, data patterns, or operational vulnerabilities.

From the tool's definition The tool 'show_query_log' displays historical query log data (DBQL) including 'SQL text, execution times, resource consumption, and performance metrics' for a specific user. It 'Returns query history with timestamps, SQL, runtime, CPU time, and I/O statistics.

POLICY

How to control show_query_log

PolicyLayer is an MCP gateway — it sits between your AI agents and Teradata Workload Management (WLM) MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for show_query_log:

policy.json

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

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