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

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

## Why list_available_fake_backends_tool is rated Low

This tool retrieves or queries available fake (simulated) quantum backends. It has no side effects—it does not execute code, modify data, delete resources, or commit financial obligations. The 'list' operation is characteristic of Read category tools. Despite the empty description reducing confidence slightly, the name strongly indicates a read-only query operation.

From the tool's own definition: "Tool name 'list_available_fake_backends_tool' indicates a listing operation. The 'list' verb and 'fake_backends' context suggest retrieval of available simulated quantum backend options without modification or execution of quantum operations."

## Use case

AI agents call list_available_fake_backends_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": {
    "list_available_fake_backends_tool": {}
  }
}
```
