WHAT IT DOES

What mysql_add_primary_key does on Mysql

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

RISK

Why mysql_add_primary_key is rated Medium

Adding a primary key modifies table schema structure reversibly (can be removed with DROP CONSTRAINT or ALTER TABLE), placing it in the Write category rather than Destructive. However, this is a high-severity Write because it affects database structure and can have cascading effects on dependent queries and applications.

From the tool's definition Tool name 'mysql_add_primary_key' and description 'Add a primary key to a table' indicate a schema modification operation. Primary key constraints are structural database modifications that alter table definition.

mysql_add_primary_key Rate-limited

mysql_add_primary_key stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
