Query Application Insights metrics
AI agents call azure_metrics to retrieve information from MCP Container Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries (reads) Azure Application Insights metrics, which is a data retrieval operation with no side effects. It does not create, modify, delete, execute commands, or commit financial transactions. The query operation on metrics is a standard monitoring/observability function that returns telemetry data for analysis.

Register the MCP Container Tools MCP server in PolicyLayer and add a rule for azure_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 MCP Container Tools. Nothing to install.
azure_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 azure_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 azure_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.
azure_metrics is provided by the MCP Container Tools MCP server (simseksem/mcp-container-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
