RISK

Why updatePermission is rated Medium

This tool modifies access permissions on Google Drive files/resources, which is a reversible write operation. However, it carries high severity because permission changes can broadly alter who can access, modify, or delete shared documents, affecting confidentiality and integrity.

From the tool's definition Tool name 'updatePermission' and description 'Update an existing permission role' indicate modification of access control settings on Google Drive resources.

RECOMMENDED RULE

The rule that runs updatePermission 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 updatePermission, this is the rule to start with:

updatePermission Rate-limited

updatePermission stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. 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 updatePermission call is checked against it from then on.
