WHAT IT DOES

What capture_frame does on Video Still Capture MCP

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

RISK

Why capture_frame is rated Low

This tool reads/captures image data from a webcam or video source without modifying any stored data. It is a data retrieval operation. Severity is medium because it can capture real-world visual/private information from a camera, posing a privacy risk if misused by an AI agent.

RECOMMENDED RULE

The rule that runs capture_frame safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Video Still Capture MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capture_frame, this is the rule to start with:

capture_frame Allowed

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

  "default": "deny",
  "tools": {
    "capture_frame": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Video Still Capture MCP, apply this rule, and every capture_frame call is checked against it from then on.
