WHAT IT DOES

What list_pyroscope_label_names does on Grafana MCP Server

AI agents call list_pyroscope_label_names to retrieve information from Grafana MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_pyroscope_label_names is rated Low

This tool retrieves metadata about available labels in Pyroscope profiling data. It performs no modifications, deletions, or external operations. The blast radius of misuse is minimal—an AI agent could at worst enumerate label names, which is informational data already exposed within the Grafana instance. This is a straightforward Read operation.

From the tool's definition Tool name 'list_pyroscope_label_names' and description 'Lists all available label names found in profiles' indicate a retrieval operation with no side effects. The verb 'list' and the passive scope (reading existing labels) confirm this is a query-only action.
