Query metric data points via Grail DQL
AI agents call query_metric to retrieve information from Dynatrace SaaS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries existing metric data from Dynatrace's Grail DQL engine. It retrieves information for analysis without creating, modifying, deleting, or executing operations. The action is read-only with minimal blast radius—worst case is exposure of metrics the user is already authorized to view.
From the tool's definition Tool name 'query_metric' and description 'Query metric data points via Grail DQL' indicate retrieval of observability data with no modification, deletion, or side effects.

Register the Dynatrace SaaS MCP Server MCP server in PolicyLayer and add a rule for query_metric: 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 Dynatrace SaaS MCP Server. Nothing to install.
query_metric 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 query_metric 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 query_metric. 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.
