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

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

## Why capture_viewport is rated Low

Capturing a viewport is a non-destructive retrieval operation with no side effects on the underlying model or data. It acquires visual information (a snapshot of the current view) without modifying, executing external operations, or creating persistent changes. Consistent with the server's read-only designation.

From the tool's own definition: "Server is explicitly described as 'Read-only Fusion 360 MCP'. Tool name 'capture_viewport' suggests acquiring/retrieving a screenshot or view state rather than modifying data."

## Use case

AI agents call capture_viewport to retrieve information from Aos 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 Aos:

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