Get current metrics.
AI agents call mysql_metrics 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.
The tool retrieves monitoring/performance metrics from MySQL without any capability to modify, delete, or execute operations. It has no side effects and poses minimal security risk. This is a straightforward Read operation.
From the tool's definition Tool name 'mysql_metrics' and description 'Get current metrics' indicate a data retrieval operation with no modification capability. The server description emphasizes 'read-only access by default', and this tool fits that pattern as a metrics query.

Register the FastMCP MySQL Server MCP server in PolicyLayer and add a rule for mysql_metrics: 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_metrics 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_metrics 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_metrics. 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_metrics 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.
