THE RISK

Low Risk

Why youtube_getInfo needs a policy

youtube_getInfo retrieves publicly available video metadata (title, description, duration, view count, etc.) with no side effects beyond caching/storing the retrieved data locally. This is a standard Read operation. While it says 'save', this refers to locally caching retrieved information, not modifying YouTube or user data. No destructive, financial, or execution risks are present.

From the tool's definition Tool description states 'Get and save YouTube video information' from a video URL. This is a retrieval operation that queries YouTube metadata.

POLICY

How to control youtube_getInfo

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

policy.json

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

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
