How to control analyze_screenshot ↓

AI agents call analyze_screenshot to retrieve information from ZMCPTools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Low Risk

This tool performs passive analysis of visual input (screenshots). While it accepts custom prompts, the core function is extracting information from already-captured images, comparable to analyzing a document or image file. There is no indication it executes code, modifies state, deletes data, or moves money.

From the tool's definition Tool description states it 'analyzes page screenshots with custom prompts' and 'provide[s] contextual insights' — these are read operations that retrieve and interpret visual information without modifying data, triggering external actions, or causing side…

Documented attack patterns abuse exactly the kind of access analyze_screenshot gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and ZMCPTools, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_screenshot:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyze_screenshot": {}
  }
}

analyze_screenshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register ZMCPTools — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
