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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "active_instance_info_tool",
    "arguments": {}
  }
}
```

## Why active_instance_info_tool is rated Low

This tool only retrieves and returns information about the current instance configuration (its CRN identifier). It performs no side effects, data modification, code execution, or destructive actions. The severity is low because disclosure of a CRN is informational and does not grant unauthorized access by itself; it is the type of metadata typically needed for normal API operations.

From the tool's own definition: "Tool description states 'Get the Cloud Resource Name (CRN) of the currently active instance' — a retrieval operation that queries metadata about the active instance without modifying, executing, or deleting anything."

## Use case

AI agents call active_instance_info_tool to retrieve information from Qiskit IBM Transpiler 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 Qiskit IBM Transpiler MCP Server:

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