get_promql_labels
AI agents call get_promql_labels to retrieve information from Amazon MQ MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The naming convention 'get_' combined with 'promql_labels' strongly suggests this is a query/retrieval operation that fetches label metadata from a Prometheus-compatible monitoring system. Such operations are read-only with no side effects. The empty description reduces confidence slightly, but the semantic meaning of the name is clear enough to classify as Read with low severity.
From the tool's definition Tool name 'get_promql_labels' indicates retrieval of Prometheus Query Language labels; no modification, deletion, or execution keywords present. Tool description is empty, which limits confidence.

Register the Amazon MQ MCP Server MCP server in PolicyLayer and add a rule for get_promql_labels: 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 Amazon MQ MCP Server. Nothing to install.
get_promql_labels 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 get_promql_labels 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 get_promql_labels. 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.
get_promql_labels is provided by the Amazon MQ MCP Server MCP server (awslabs.amazon-mq-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
