## Facts

- Tool: `ui_diff`
- Server: Iconnect (`iconnect-mcp`) — https://policylayer.com/tools/io-github-heznpc-iconnect.md
- Install: `npx -y iconnect-mcp`
- Homepage: https://github.com/heznpc/iConnect
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why ui_diff is rated Low

This is fundamentally a data retrieval and analysis tool. It queries the current UI state and compares it against a stored snapshot to identify differences. There are no side effects, no data modification, no code execution, and no irreversible actions. The tool only reads and reports on UI state information, making it a Read category risk with low severity.

From the tool's own definition: "Tool compares and detects changes between UI states; it 'Compare[s] the current UI state against a previous snapshot' with no mention of modification, deletion, or execution of external operations."

## Use case

AI agents call ui_diff to retrieve information from Iconnect 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 Iconnect:

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