Turn Gmail into an AI inbox assistant for your team. This setup lets an AI agent search, label, draft, and reply to emails from one place. It fits support and sales teams that need faster responses and a tidy inbox every day.

At the core is a Gmail MCP Server that exposes many Gmail actions as tools your agent can call. Linked nodes cover messages, labels, drafts, and full threads. The agent can search mail by query or sender, open a message, mark it read or unread, add or remove labels, and send a reply with CC, BCC, and attachments. It can also create and manage labels, save drafts before sending, list and fetch drafts, and reply inside a thread to keep context and history.

Setup is simple. Connect a Gmail account in n8n Cloud, then copy the SSE server URL from the Gmail MCP Server node into your AI agent or MCP client and activate the workflow. Teams usually cut manual sorting from hours to minutes and raise first reply speed, which helps with inbox triage, lead follow up, and routine operations updates. Results are easy to track through clear labels and sent items in Gmail.

• Connect Gmail to AI agents through one secure server endpoint

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with Gmail. See the Tools Required section above for links to create accounts with these services.
3. In the n8n credentials manager, create a Gmail OAuth2 credential. Double click any Gmail node, open the Credential to connect with dropdown, click Create new credential, then follow the on screen steps to grant access.
4. Name the credential clearly, for example Gmail Primary, and save it. Assign this credential to all Gmail tool nodes using the credential dropdown.
5. Open the Gmail MCP Server node and copy the SSE server URL shown in the node.
6. In your AI agent flow in n8n or in another MCP client, add a new tool server and paste the SSE server URL. Enable the tool server so the agent can call Gmail tools.
7. Activate the workflow in n8n so the server is available to your agent.
8. Validate access by asking your agent to call getLabels. Confirm that a list of Gmail labels is returned.
9. Run a safe search test with a simple query like from:youremail to confirm message IDs and details are returned.
10. Send a test message to yourself and use the reply or replyThread tool to respond. Check Gmail Sent and the thread history to confirm success.
11. Troubleshooting: If you see permission errors, reconnect the Gmail credential and ensure it has email, labels, and drafts scopes. If a label is missing, run createLabel first. If a message or thread ID fails, fetch it with search or getManyThreads before calling other tools.
