WHAT IT DOES

What get_screen_code does on Stitch MCP Server

AI agents call get_screen_code to retrieve information from Stitch MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_screen_code is rated Low

This tool retrieves and fetches existing HTML code without creating, modifying, deleting, or executing anything. It has no side effects beyond returning data. The operation is purely informational—fetching a download URL and viewing code does not alter any state. Low severity reflects minimal blast radius if misused; an agent could view unintended HTML code but cannot damage systems or data through this tool alone.

From the tool's definition Tool is named 'get_screen_code' and described as 'Retrieve the HTML code download URL (and extract full HTML if possible)'. The verbs 'retrieve' and 'extract' indicate read-only operations with no data modification or deletion.

RECOMMENDED RULE

The rule that runs get_screen_code safely

get_screen_code Allowed

get_screen_code is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_screen_code": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Stitch MCP Server, apply this rule, and every get_screen_code call is checked against it from then on.
