WHAT IT DOES

What send-draft does on MCP Google Workspace

AI agents use send-draft to create or update resources in MCP Google Workspace, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Google Workspace environment.

RISK

Why send-draft is rated Medium

Sending an email is a Write/communication action that delivers a message to external parties. It cannot be undone (the sent email cannot be unsent), making misuse high severity — an agent could send confidential or malicious content to unintended recipients. The draft deletion is a minor destructive side effect, but the dominant and most impactful action is the irreversible external communication.

From the tool's definition 'Send saved draft' and 'sending previously created draft' — dispatches an email to external recipients; 'draft is deleted after sending' is a side effect but the primary action is sending

RECOMMENDED RULE

send-draft Rate-limited

send-draft 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.
