execute_dbsql · Databricks MCP Server MCP: Risk & Policy

WHAT IT DOES

What execute_dbsql does on Databricks MCP Server

AI agents invoke execute_dbsql to trigger actions in Databricks 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_dbsql needs a policy

Executing SQL queries is a code execution action with effects dependent on the query content—an AI agent could run queries that modify, delete, or corrupt data. It is not Read-only because SQL execution can include DML/DDL operations (INSERT, UPDATE, DELETE, CREATE, ALTER, DROP).

From the tool's definition Tool name 'execute_dbsql' indicates execution of SQL queries against Databricks SQL warehouses. Server description confirms 'running SQL queries' as a core capability.
