Removes the specified delegate
AI agents call remove_delegate to permanently remove resources in Gmail MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a delegate revokes another user's access to the Gmail account. This is an irreversible action (the delegation must be re-created to restore access), making it Destructive. The blast radius is high because it could disrupt legitimate access arrangements or be used to lock out authorized delegates.
From the tool's definition 'Removes the specified delegate' — permanently removes an access delegation, which is an irreversible account configuration change

Register the Gmail MCP Server MCP server in PolicyLayer and add a rule for remove_delegate: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gmail MCP Server. Nothing to install.
remove_delegate is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_delegate rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for remove_delegate. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
