AI agents use mysql_create_database to create or update resources in Mcp Windows — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Windows environment.
This tool creates a new database, which is a reversible write operation. While databases are important infrastructure, creating one does not permanently destroy data or execute arbitrary code; it can be reversed by dropping the database.
From the tool's definition Tool name is 'mysql_create_database' and description states 'Create a new MySQL database.' The verb 'create' indicates data creation/modification.
Documented attack patterns abuse exactly the kind of access mysql_create_database gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_create_database:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_create_database": {
"limits": [
{
"counter": "mysql_create_database_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}mysql_create_database 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.
Free to start. No card required.
Create a new MySQL database. It is categorised as a Write tool in the Mcp Windows MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for mysql_create_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 Mcp Windows. Nothing to install.
mysql_create_database is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the mysql_create_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_create_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_create_database is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
