Gmail MCP and Claude skills
Search your Gmail inbox for unread mail, threads waiting on your reply and messages from key senders, and post a short triage list.
Connect Gmail to your agent (MCP)
- Claude's Gmail connector. In Claude, connect Gmail from the connector directory with your Google account to search and read your mail.
- Gmail MCP server, Google's own remote server at
https://gmailmcp.googleapis.com/mcp/v1, in developer preview with the other Google Workspace MCP servers. It needs an OAuth client in Google Cloud set up for an AI agent (setup). - Gmail API with OAuth. Create a desktop OAuth client, authorize once with the
gmail.readonlyscope, and storeGMAIL_CLIENT_ID,GMAIL_CLIENT_SECRETandGMAIL_REFRESH_TOKEN. Publish the OAuth app (or make it Internal in Workspace): refresh tokens from an app left in Testing expire after seven days.
gmail.readonly can search and read but not send, delete or relabel; add gmail.compose only if you want the agent to leave drafts.

Agents read Gmail with users.messages.list and users.threads.list, which accept the same operators as the Gmail search box: in:inbox is:unread newer_than:1d, -category:promotions -category:social, from:@acme.com, has:attachment filename:pdf, label:clients older_than:3d. users.threads.get returns every message in a thread with its headers (From, To, Subject, Date), labels and snippet, so an agent can tell whether the last word was yours or theirs.
Founders and sales leads schedule a morning triage of unread mail that needs an answer, threads where someone has waited three days for your reply, invoices and receipts that arrived this week, and replies from a list of leads or customers.
