execute_raw_query · Redash MCP Server MCP: Risk & Policy

WHAT IT DOES

What execute_raw_query does on Redash MCP Server

AI agents invoke execute_raw_query to trigger actions in Redash MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why execute_raw_query needs a policy

This tool allows execution of arbitrary SQL queries with no guardrails mentioned. While SQL execution alone could be Read, Write, or Destructive depending on query content, the 'raw' and 'directly' qualifiers indicate the tool itself does not restrict query type—an AI agent could accidentally or maliciously execute DROP, DELETE, INSERT, UPDATE, or data exfiltration queries.

From the tool's definition Tool name 'execute_raw_query' combined with description 'Execute a raw SQL query directly and return results' indicates execution of arbitrary SQL code.
