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

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

## Why take_viewport_screenshot is rated Low

This tool performs data retrieval and capture of visual output only. It does not modify, delete, execute code, move data, or trigger external operations. The screenshot is a passive observation of the viewport state. While it creates a file, this is a benign side-effect of logging/documentation, not a Write operation that modifies application state or data structures.

From the tool's own definition: "Tool description states it 'Capture[s] a screenshot of the current ParaView viewport and save[s] it as a timestamped PNG' — a read-only operation that captures and stores visual data without modifying any underlying scientific data or system state."

## Use case

AI agents call take_viewport_screenshot to retrieve information from CLIO Adios 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 CLIO Adios:

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