AI agents call mysql_drop_database to permanently remove resources in Mysql — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes an entire database and all its contents, which cannot be undone. This is the most severe category (Destructive) as it causes irreversible data loss. The critical severity reflects the maximum blast radius—an AI agent misusing this could destroy production data with a single call.
From the tool's definition Tool name explicitly states 'drop_database'; description includes 'Drop a MySQL database' with warning 'USE WITH CAUTION!'. Drop operations irreversibly delete data.
Documented attack patterns abuse exactly the kind of access mysql_drop_database gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mysql, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_drop_database:
{
"version": "1",
"default": "deny",
"hide": [
"mysql_drop_database"
]
}mysql_drop_database disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
Free to start. No card required.
Drop a MySQL database (USE WITH CAUTION!). It is categorised as a Destructive tool in the Mysql MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_drop_database: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mysql. Nothing to install.
mysql_drop_database is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the mysql_drop_database rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mysql_drop_database. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mysql_drop_database is provided by the Mysql MCP server (mukul975/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mysql, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
