Why getGoogleDocImage is rated Low
This tool retrieves image data from Google Docs and returns it for viewing. It performs a read-only operation—fetching and displaying content that already exists. There is no creation, modification, deletion, code execution, or financial impact. The re-fetching of the document to ensure fresh URLs does not constitute a side effect that would elevate the classification beyond Read.
From the tool's definition Tool name 'getGoogleDocImage' and description 'Fetch the bytes of an inline image' indicates retrieval of existing data with no modification or side effects.
Attacks that exploit this kind of access
The rule that runs getGoogleDocImage safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Google Drive, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getGoogleDocImage, this is the rule to start with:
getGoogleDocImage is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Google Drive, apply this rule, and every getGoogleDocImage call is checked against it from then on.
