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

```json

## Why get_global_var is rated Low

This tool retrieves configuration data (global variables) from an application delivery system. It performs a query/read operation that does not create, modify, delete, execute code, or trigger external actions. The blast radius of misuse is minimal—an AI agent could at most read variable values that may already be accessible to authorized users.

From the tool's own definition: "Tool name is 'get_global_var' and description states 'Get a global variable group' — the verb 'Get' and lack of modification language indicate a retrieval operation with no side effects."

## Use case

AI agents call get_global_var to retrieve information from Alibabacloud Devops 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 Alibabacloud Devops:

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