Gmail MCP Server

This is Google's official Gmail MCP server. Claude can search your mail, read threads, write drafts and organise everything with labels, all through Google's own API.

It's still in Developer Preview, and right now it drafts rather than sends: there are no tools for sending, attachments or deleting yet. If you want Claude to handle Calendar and Drive too, the Google Workspace MCP covers more ground.

Setup takes a few minutes in Google Cloud: enable the Gmail MCP API, create an OAuth client, then connect it to Claude.

• Search your inbox and read whole threads
• Write reply drafts for you to check and send
• Create labels and sort messages into them
• Pull the details out of a message, like dates or order numbers

Open your terminal in the project folder and run:

claude mcp add --transport http gmail https://gmailmcp.googleapis.com/mcp/v1 --client-id YOUR_CLIENT_ID --client-secret

Or add this to your project's .mcp.json:

# First enable the API in your Google Cloud project:
gcloud services enable gmailmcp.googleapis.com --project=PROJECT_ID
# Then create an OAuth client (Google Auth Platform > Clients) and use its ID above.

You'll be asked to sign in or paste an API key the first time you use it.
