Mcp Google Gmail

English | Русский

A1 Gmail MCP lets an AI app work with your Gmail mailbox in plain language. Search and read mail, prepare replies as drafts, send them when you are ready, keep labels tidy and use the trash instead of permanent deletion.

It uses the Gmail API with your Google account. It distinguishes a draft you can still edit from a sent email that cannot be recalled, and makes the limits of the Gmail API explicit instead of implying that every mail task is reversible.

• 18 tools. Search and read messages and threads, send email directly or through drafts, manage the draft lifecycle, labels and the trash.
• Send deliberately. The draft → review → send path is first-class; sending is marked destructive, and the server never re-sends after an ambiguous failure — an email cannot be unsent.
• The trash is the safety net. Removing mail goes through the reversible trash (about 30 days); there is deliberately no permanent message delete tool.
• Bounded reading. Decoded bodies are truncated at an explicit limit and attachments come back as metadata, so a long newsletter cannot silently flood the conversation.
• Minimal Google scope. It uses gmail.modify only — no permanent deletion and no access to Gmail settings.

Start with a read-only question:

Show my unread emails from the last week and tell me which ones need a reply.

You: What is unread in my inbox from this week about the Acme contract?

Assistant: Searches with Gmail query syntax and shows senders, subjects, dates and snippets. Nothing changes.

You: Draft a reply to the latest one: we send the signed copy on Friday.

Assistant: Creates a draft in the same thread and shows it for review. Nothing is sent.

You: Send it.

Assistant: Sends the draft. Sending is a separate, explicitly destructive step, so your AI app can ask for confirmation first.
