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

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

## Why find_error_pattern_logs is rated Low

This tool performs a comparative search/query of log data (comparing error patterns to historical baseline from the last day). It has no side effects, does not modify data, execute code, delete records, or incur financial obligations.

From the tool's own definition: "Tool name and description indicate it 'Searches Loki logs for elevated error patterns' — a read-only query operation that retrieves and analyzes existing log data without modifying, deleting, or executing operations."

## Use case

AI agents call find_error_pattern_logs 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": {
    "find_error_pattern_logs": {}
  }
}
```
