Get the content of multiple email messages by their IDs.
AI agents call get_emails to retrieve information from Mcp Gmail without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves email message content by ID, which is a read operation with no side effects or destructive capability. However, severity is medium rather than low because email content may contain sensitive personal information, credentials, or confidential data that could be exposed if an AI agent accesses emails without proper authorization or context.
From the tool's definition Tool name 'get_emails' and description 'Get the content of multiple email messages by their IDs' indicate data retrieval with no side effects. The verb 'get' and lack of any modification language confirm this is a read operation.

{
"version": "1",
"default": "deny",
"tools": {
"get_emails": {}
}
}get_emails is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
