WHAT IT DOES

What mysql_spatial_create_column does on Mysql Mcp

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

RISK

Why mysql_spatial_create_column is rated Medium

Adding a column to a table modifies the database schema but is reversible (the column can be dropped). This fits the Write category—it creates/modifies data structures. Severity is high because schema changes can affect application functionality, dependent views, triggers, and performance, and errors may cascade. However, it does not fall under Destructive (the change is not irreversible) or Financial.

From the tool's definition Tool name and description indicate it 'Add[s] a geometry/spatial column to an existing table.' This is a schema modification operation that creates a new column, which is a reversible write operation.

RECOMMENDED RULE

The rule that runs mysql_spatial_create_column safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_spatial_create_column, this is the rule to start with:

mysql_spatial_create_column Rate-limited

mysql_spatial_create_column 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.
