Google Workspace MCP vs MCP Gsuite

get_gmail_messages_content_batch

Retrieves the content of multiple Gmail messages in a single batch request. Supports up to 25 messages per batch to prevent SSL connection exhaustion.

get_gmail_attachment_content

Downloads an email attachment and saves it to local disk. In stdio mode, returns the local file path for direct access. In HTTP mode, returns a temporary download URL (valid for 1 hour). May re-fetch message metadata to resolve filename and MIME type.

send_gmail_message

Sends an email using the user's Gmail account. Supports new emails, replies, and forwards, with optional attachments. Supports Gmail's "Send As" feature to send from configured alias addresses. To forward an existing message, pass forward_message_id. The original subject, body (quoted with a "Forwarded message" header), and attachments are carried over. In forward mode, body (if any) is prepended as a note and subject is optional. Threading, reply, and signature options do not apply when forwarding. THIS TOOL SENDS IMMEDIATELY AND CANNOT SCHEDULE. Gmail's REST API exposes no send-time parameter; Schedule send is a web-UI feature with no API equivalent, so no argument to this tool can defer delivery. Never tell a user a message was scheduled. For "prepare now, deliver later", create a draft with draft_gmail_message. An external scheduler must retain the message data to create and send a new message via send_gmail_message at the chosen time, or call users.drafts.send with the draft ID returned by draft_gmail_message. Alternatively, let the user schedule that draft in the Gmail UI.

draft_gmail_message

Creates a draft email in the user's Gmail account. Supports both new drafts and reply drafts with optional attachments. Supports Gmail's "Send As" feature to draft from configured alias addresses. SCHEDULED SEND IS NOT AVAILABLE. Gmail's REST API exposes no send-time parameter; the Schedule send feature is web-UI only, and a message cannot be placed in the Scheduled folder through the API. Do not claim a message was scheduled. To deliver at a chosen time, create a draft with draft_gmail_message. An external scheduler must retain the message data to create and send a new message via send_gmail_message then, or call users.drafts.send with the draft ID returned by draft_gmail_message. Alternatively, let the user schedule the draft in the Gmail UI.

get_gmail_thread_content

Retrieves the complete content of a Gmail conversation thread, including all messages. Optionally also returns structured ownership analysis so a caller can determine who sent the last message and who owes whom a response without re-parsing the formatted string or making a second tool call.

get_gmail_threads_content_batch

Retrieves the content of multiple Gmail threads in a single batch request. Supports up to 25 threads per batch to prevent SSL connection exhaustion.

list_gmail_labels

Lists labels in the user's Gmail account.

manage_gmail_label

Manages Gmail labels: create, update, or delete labels.

list_gmail_filters
