## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "list_pyroscope_label_values",
    "arguments": {}

## Why list_pyroscope_label_values is rated Low

This tool retrieves metadata about available profiling label values without modifying, executing, or deleting any data. It has no side effects and represents a safe read operation on monitoring data. The blast radius of misuse is minimal—an agent could only spam requests or learn about the profiling system's structure, neither of which causes harm.

From the tool's own definition: "Tool name contains 'list' and description states 'Lists all available label values' - a retrieval operation with no side effects. Pyroscope is a profiling database where querying label values is purely informational."

## Use case

AI agents call list_pyroscope_label_values 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Grafana MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_pyroscope_label_values": {}
  }
}
```
