mysql_create_table · MySQL MCP Server MCP: Risk & Policy

WHAT IT DOES

What mysql_create_table does on MySQL MCP Server

AI agents use mysql_create_table to create or update resources in MySQL MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MySQL MCP Server environment.

WHY IT NEEDS A POLICY

Why mysql_create_table needs a policy

Creating a table is a Write operation: it modifies the database schema by adding a new persistent data structure. While reversible (a table can be dropped), it is more severe than simple record insertion because it affects database structure and can impact dependent queries, views, or applications. It is not Destructive because the action itself is reversible and doesn't inherently delete data.

From the tool's definition Tool is named 'mysql_create_table' with description 'Create a new table with specified columns and constraints' — this creates a new data structure in the database, a reversible but consequential modification.
