Get health status of MySQL server.
AI agents call mysql_health to retrieve information from FastMCP MySQL Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic information about the MySQL server's operational status. It is a read-only operation with no side effects, data modifications, or command execution capabilities. The low severity reflects minimal blast radius—an AI agent misuse would only expose health metrics, not compromise data or operations.
From the tool's definition Tool name 'mysql_health' and description 'Get health status of MySQL server' indicate a query operation that retrieves server status information without modifying data or executing arbitrary operations.

Get health status of MySQL server. It is categorised as a Read tool in the FastMCP MySQL Server MCP Server, which means it retrieves data without modifying state.
Register the FastMCP MySQL Server MCP server in PolicyLayer and add a rule for mysql_health: 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 FastMCP MySQL Server. Nothing to install.
mysql_health is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mysql_health 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_health. 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_health is provided by the FastMCP MySQL Server MCP server (jinto/fastmcp-mysql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
